v0.3.0

Changelog

All notable changes to Hanterill are documented here. Versioning is SemVer.

Hanterill 0.3.0

Released: 2 October 2026

Hanterill 0.3.0 is one of the largest updates so far.

This release expands what Hanterill can inspect across the battery, charging system, drive units, infotainment, connectivity, vehicle history and service systems. It also introduces much stricter handling of incomplete or uncertain diagnostic results.

A major focus of 0.3.0 has been making sure Hanterill tells you what the car actually reported, rather than filling gaps with assumptions.

Highlights

Drive-unit history

A new Drive Units view provides much deeper information about the front and rear electric motors.

Depending on available data, Hanterill can show:

• operating time
• powered time
• regeneration usage
• acceleration usage
• torque availability
• motor temperatures
• inverter temperatures
• coolant temperatures
• current history
• torque and speed distributions
• operating-condition heat maps
• voltage-spike history

The view also makes it easier to compare front and rear drive-unit usage.

Where historical band boundaries or physical scales are still being researched, they remain clearly marked as provisional.

Charge history

Hanterill can now show lifetime AC and DC charging counts when the related vehicle records agree with each other.

If the underlying records disagree, Hanterill does not invent a number. The result is left unresolved and the discrepancy is shown.

Historical charge distributions are also visualised as charts.

Where the exact boundaries of a charge band have not yet been established, Hanterill shows numbered bands rather than pretending they represent known percentages.

A better reset module

Resetting a single ECU now says exactly what happened. Hanterill asks for explicit confirmation, reports whether the controller acknowledged the request, and shows outcome unknown when it cannot tell whether the reset finished. Cached readings are cleared afterwards so stale values are not shown as fresh, and the ECU page disables the BECM reset up front instead of letting you start something that would be refused.

The recorded reset-all procedure runs as a cancellable job with VIN verification and three explicit confirmations. Hanterill separates request delivered from vehicle physically rebooted, a cancelled or interrupted run still returns its partial results, and the confirmation dialog and audit log state what was actually sent.

Generic broadcast resets and a direct BECM reset remain blocked. See ECU and service functions for the details.

A better interface

Owner-facing screens now lead with understandable names such as battery voltage or coolant temperature instead of diagnostic identifiers. Raw codes remain in the expert tools.

The Battery page has separate full-width sections, so large cell maps no longer overlap neighbouring information. The light and dark themes use cleaner neutral surfaces and one consistent blue accent. Fault-code rows show their description in the list, the Live Data catalogue has All signals, Selected and Favourites views, and a Demo Mode banner appears on every screen. Keyboard and accessibility support have also improved. See User interface for the full list.

New icons and logo

Hanterill has a new logo mark, in a colour version and a version for dark backgrounds, and a new browser icon.

The application icon has been replaced for Windows and macOS, including the sizes Windows uses for tiles and the Store listing.

Deeper battery diagnostics

The Battery pages now show per-cell State of Health, capacity and State of Charge, module temperatures from the pack's own sensors, charging history, and contactor and pre-charge history.

The Battery Health verdict now takes the reported State of Health into account, and a partial cell read is shown as an incomplete measurement instead of being graded as a full inspection.

More reliable fault codes

Active, pending and stored codes are now handled the same way on the Fault Codes page, the Overview and the Inspection Report. A module that was not read shows Not read instead of looking clean, and clearing codes no longer claims success without evidence.

New infotainment diagnostics

Hanterill now has a dedicated Infotainment page for the car's Android Automotive head unit and audio amplifier.

Depending on what the vehicle reports, it can show:

• Android version
• software build
• security patch level
• hardware information
• part and software numbers
• storage wear estimate
• infotainment restart history
• cloud-service errors
• connection history
• software-update history
• audio amplifier information

Software update records are translated into plain descriptions such as installed, failed and retried, or withdrawn before completion.

A new Since your last reading section can also highlight new restarts, connection changes, cloud errors and software-update activity since the previous read.

The infotainment page is deliberately owner-focused. Technical values that cannot yet be explained reliably are not presented as meaningful vehicle information.

TCAM connectivity diagnostics

The TCAM page now includes a new Connectivity section.

It can inspect information reported by the vehicle about:

• cloud connectivity
• service discovery
• provisioning
• cellular connectivity
• mobile network registration
• connection history
• failed network registrations
• modem software
• emergency-call system software

Hanterill does not attempt to interpret unknown network rejection codes or turn them into a good/bad verdict.

Potential identifiers found in the returned data are also redacted before being displayed.

Improved TCAM and GPS information

The TCAM page has been redesigned to better explain what the module is actually reporting.

GNSS data is now identified and presented as navigation/positioning information rather than a large block of hexadecimal data.

Where available, Hanterill can show information such as:

• fix state
• satellites
• signal-quality information
• TCAM software information
• module status
• backup-battery information

Coordinates remain on the GPS page behind the existing location consent controls.

Better TCAM backup-battery diagnostics

Backup-battery readings are now more transparent.

If the normal reading is unavailable and Hanterill has to use an alternative method, the app shows what happened instead of simply reporting that no reading was attempted.

Measured values are also no longer thrown away simply because they fall outside an expected voltage range. An unusual value is shown and flagged rather than hidden behind a decode error.

This is particularly important when investigating a genuinely failing TCAM backup battery.

---

Battery diagnostics

Much deeper battery information

Battery diagnostics have received another major expansion.

Depending on vehicle and platform support, Hanterill can now show:

• battery State of Health
• per-cell State of Health
• per-cell learned capacity
• per-cell State of Charge
• cell voltages
• cell balance
• battery-module temperatures
• hottest and coldest modules
• temperature spread
• battery awake time
• AC and DC charging history
• time spent in different charge bands
• contactor behaviour
• pre-charge history
• isolation-related information
• battery identity information
• additional lifetime statistics

The cell views have also been improved with clearer heat maps and better highlighting of the strongest, weakest, hottest and coldest areas of the pack.

Battery Health now considers actual degradation

The Battery Health verdict now considers the battery's SoH classification before declaring the pack healthy.

Previously, good cell balance could potentially result in a positive overall result even when the reported State of Health itself was below the relevant warranty threshold.

A healthy-looking cell map can no longer override a poor SoH result.

Partial cell reads are no longer treated as complete

Cell-balance classifications are now only applied when Hanterill actually obtained enough data to justify them.

A partial cell sweep is shown as an incomplete measurement, rather than being graded as though the whole battery was inspected.

The same rule is now used on the Battery page and in exported reports.

Better explanation when battery data is missing

When a per-cell SoH, capacity or State of Charge reading is unavailable, Hanterill now records why.

Instead of simply showing an empty value, the app can distinguish between situations such as:

• the module did not answer
• the read failed
• the returned data could not be decoded
• the result was outside the expected range
• the measurement was incomplete

This makes it much easier to distinguish a genuine battery issue from a failed diagnostic read.

Correct battery temperature data

The battery thermal map now uses the battery pack's actual module temperature sensors.

This replaces an earlier interpretation that could produce misleading high/low battery-temperature values.

For supported CMA vehicles, Hanterill can now display the pack's 27 modules with two temperature sensors per module and identify the warmest and coolest areas of the pack.

Corrected State of Charge readings

The primary State of Charge readings now come from the BECM's own confirmed values.

Multiple available sources are compared and the app tells you whether they agree instead of silently choosing one.

Corrected battery-capacity reference

Capacity fade calculations now use the reference derived from the vehicle's own battery data...

v0.2.2

Hanterill 0.2.2

Massive update focused on stability, vehicle support, diagnostics, localization and making the information Hanterill presents easier to understand.

Hanterill is still in beta. Vehicle support continues to expand and some features, readings and service functions are still experimental or require additional validation on real vehicles. Just because it's there doesn't mean it works, alot of the service items are placeholders and full implementation has not been released

Version 0.2.2 is one of the largest Hanterill updates so far.

This release adds significantly improved diagnostic support for Volvo SPA1 vehicles such as the XC60, XC90, V60 and S60, together with new connection methods for Polestar 4 and other SEA-platform vehicles.

A lot of work has also gone into reliability. Hanterill is now much better at distinguishing between a vehicle that did not respond, a communication problem, unsupported data and a value that could not be decoded. Incomplete scans can be resumed, failed ECUs can be retried individually, and existing captures can be re-analysed as Hanterill's diagnostic database improves.

The interface has also received a major redesign based more closely on Microsoft's Fluent 2 design language. Pages now focus on understandable findings and vehicle information first, while raw diagnostic identifiers remain available in the advanced tools.

Localization has received a substantial update as well. Dutch and Chinese have been added as new languages, while the existing translations have been reviewed and improved across the application.

Highlights

• Improved Volvo SPA1 support
• New Polestar 4 / SEA connection fallback
• More reliable DID scanning and scan recovery
• Better battery diagnostics and history
• Clearer explanations when vehicle data cannot be read
• Improved DTC scanning and comparison
• New vehicle configuration reports
• Improved service-routine safety information
• Major Fluent 2 interface refresh
• Dutch language support
• Chinese language support
• Improved translations across existing languages

Added

• Dutch language support.
  Hanterill is now available in Dutch across the desktop application, including the main navigation, vehicle pages, diagnostics, settings and newer features.

• Chinese language support.
  Chinese has been added as a new application language, covering the main interface, diagnostic pages, settings, reports and other user-facing areas.

• Clearer battery diagnostics.
  When a battery value such as State of Health, State of Charge or learned capacity cannot be read, Hanterill now explains what happened instead of simply showing an empty value. It can distinguish between a module that did not answer, an invalid response, a decoding problem and a reading that is not supported.

• State of Charge cross-checking.
  Hanterill can compare State of Charge readings reported by different vehicle systems and show whether they agree. If one of the expected sources is unavailable, the missing source is identified.

• Battery history and CSV export.
  Saved sessions can now be used to follow State of Health, State of Charge and battery-cell variation over time. History can also be exported to CSV for use in Excel or other analysis tools.

• Per-vehicle battery history.
  Battery trends are now kept separate for each vehicle, preventing readings from different cars from accidentally being compared.

• More reliable DID scans.
  The DID Scanner now shows how much of the planned scan was actually completed. If communication is lost halfway through a scan, it will no longer appear as though the entire scan completed successfully.

• Resume incomplete scans.
  Interrupted DID scans can now be continued without starting again. Previously verified results are preserved and Hanterill shows what remains to be checked.

• Retry failed ECUs only.
  Communication failures with individual modules can now be retried without repeating the entire discovery process.

• Re-analyse existing captures.
  Previously recorded scans can be analysed again using the latest Hanterill diagnostic database. This means improvements in newer versions may reveal additional information from captures you already have.

• Improved Volvo SPA1 support.
  Diagnostic coverage has been expanded for SPA1 vehicles including the Volvo XC60, XC90, V60, S60 and related models.

• Additional SPA battery information.
  Early support now includes State of Charge, State of Health, pack voltage and battery-cell information. Data that still requires additional real-vehicle validation is clearly marked.

• Polestar 4 / Geely SEA connection fallback.
  Some SEA vehicles do not respond to the normal discovery process. Hanterill can now attempt a direct connection using known SEA gateway addresses when standard discovery does not receive a response.

• SEA discovery diagnostics.
  Hanterill can identify cases where a vehicle is visible on the diagnostic network but is not accepting a diagnostic connection.

• DHCP-based diagnostic Ethernet support.
  Hanterill can now recognise situations where the vehicle expects the computer to obtain an Ethernet address through DHCP and explain this instead of simply reporting a failed connection.

• ECU reset controls.
  Supported ECUs can now be reset from their ECU page. Vehicle-wide reset options are also available from Service Routines where supported.

• Immobilizer and transponder information.
  Available key and transponder information can now be displayed on supported vehicles.

• Registered key count.
  Hanterill can now read the number of registered keys where the vehicle exposes this information.

• Offline DTC decoding.
  Captured fault-code data can be pasted into Hanterill and decoded without connecting to a vehicle.

• Fault-scan comparison.
  A new fault-code scan can be compared with the previous saved scan for the same vehicle, making it easier to identify new, cleared or recurring faults.

• Session evidence export.
  Diagnostic evidence collected during a session can now be exported as JSON.

• Connection wire log.
  The Connection page can display the diagnostic requests and responses exchanged with the vehicle, including response times and negative responses.

• Vehicle configuration reports.
  Hanterill can generate printable configuration reports containing information such as VIN, mileage and decoded vehicle options.

• Configurable report privacy.
  Report contents, units and privacy options can be configured from Settings. Location information remains disabled by default and is only included when explicitly enabled.

Improved

• Improved translations across the application.
  Existing languages have been reviewed and updated, particularly on newer pages and features. Missing strings, inconsistent terminology and untranslated interface elements have been corrected across diagnostics, reports, settings and vehicle information.

• Better localization of dates, times and reports.
  Dates and timestamps now follow the selected language and locale more consistently, including normal local date formats and 24-hour time where appropriate.

• A much cleaner interface.
  The desktop application has been redesigned around Microsoft's Fluent 2 design language, with better spacing, typography, navigation and responsive behaviour.

• More understandable vehicle information.
  Normal pages now prioritise names such as "Battery State of Health", "Backup-battery voltage" and "Software version" instead of leading with diagnostic identifiers.

• Technical information is still available.
  DID codes, ECU addresses and raw diagnostic information remain available in the DID Explorer, Scanner, ECU pages and other advanced diagnostic tools.

• Overview now focuses on findings instead of raw numbers.
  Battery condition, odometer consistency, State of Charge agreement, diagnostic coverage and other checks are presented as understandable findings.

• Better handling of missing information.
  Instead of simply displaying "Unavailable", Hanterill increasingly explains which module or reading could not be obtained and why.

• Improved connection diagnostics.
  Connection errors now distinguish between situations such as no vehicle being detected, a request not being sent, an ECU not answering, an unsupported response, a closed diagnostic port and a timeout.

• Safer Service Routines.
  Procedures now show their verification level, prerequisites and risk more clearly before they are executed.

• More reliable communication with slower ECUs.
  Diagnostic timing has been improved and Hanterill now respects ECU-provided timing information where available.

• Better session switching.
  If an ECU requires another diagnostic session, Hanterill can switch session and retry rather than immediately treating the request as unsupported.

• Improved software and part-number decoding.
  More formats used by Volvo, Polestar and related vehicle platforms can now be recognised.

• More consistent desktop and CLI results.
  Major diagnostic results now use the same underlying information across the desktop application and command-line interface.

Localization

Hanterill continues to become more accessible to users outside the original English interface.

New in 0.2.2:

• Dutch has been added as a supported language.
• Chinese has been added as a supported language.
• Existing language translations have been reviewed and expanded.
• Newer diagnostic pages now have significantly better translation coverage.
• Terminology has been made more consistent between pages.
• Reports, dates, timestamps and settings better respect the selected locale.
• Previously ...

v0.2.1

[0.2.1] - 2026-09-19

This release adds more than 20,000 manufacturer-reference entries covering over
100 vehicle modules, expands diagnostics for combustion and plug-in hybrid
vehicles, and improves scan recovery and reporting. Hanterill now distinguishes
more clearly between values reported by the vehicle, manufacturer-reference
data, unverified information, and unavailable data.

Added

• Added more than 20,000 documented manufacturer-reference entries across over
  100 vehicle modules. Selected entries can be checked against a connected
  vehicle.
• Added a Capabilities view for supported systems, modules, service information,
  and vehicle capabilities.
• Added an Engine view for supported combustion and plug-in hybrid vehicles,
  backed by hundreds of additional engine-related reference definitions.
  Unverified values remain marked until they are confirmed against a matching
  vehicle.
• Added live readings for engine coolant temperature, engine oil level and
  temperature, fuel level, fuel-pump status, diesel particulate filter data,
  gearbox oil temperature, gearbox adaptation mileage, and 48V battery charge.
• Added scan previews that show the expected support and approximate scope of an
  advanced scan before it begins.
• Added collection of fault-related operating conditions and counters when the
  module provides them.
• Added raw diagnostic responses to session history so module replies remain
  available after the vehicle disconnects.
• Added vehicle-wide ECU reset with state checks. Functions that have not been
  verified on vehicles remain unavailable.
• Added an optional update check in Settings. It is disabled by default, never
  downloads or installs an update, and sends no vehicle information.

Changed

• Fault clearing now targets modules with detected faults by default, with a
  separate option for clearing the whole vehicle. Progress identifies the
  module currently being cleared, verified, or reset, and preserves the before
  and after results for comparison.
• Compatible reads from the same module now share a diagnostic session, reducing
  repeated vehicle communication during larger scans.
• A non-responsive module no longer blocks the rest of a scan. Hanterill reports
  the missing response and continues with the remaining modules.
• Fault-code scans can recover from temporary connection loss. Before combining
  results, Hanterill checks that the same vehicle has reconnected.
• Platform-specific scans now account for module addressing and omit
  combustion-only modules when scanning an electric vehicle.
• Battery diagnostics show more health information, record connection and
  disconnection activity, and sort module readings more clearly.
• Temperature channels that remain static or otherwise look unreliable are
  identified instead of being presented as confirmed measurements.
• Modules for equipment that was never fitted can be marked as expected absent,
  with the related option or system shown when known.
• Reports and snapshots show the full VIN by default. VIN masking remains
  available when preparing data for sharing.
• Measurements use appropriate precision, conflicting service values are easier
  to identify, and each service value names its source module.
• Compatible diagnostic requests can be grouped, and long recordings are
  written progressively to reduce memory use.
• Large visual components load only when needed.
• Keyboard navigation now covers battery cells, module views, and ECU lists more
  consistently. Buttons and overlays respond sooner, and live charts retain
  their zoom level.
• Revised all eight translations, including broader rewrites of the Danish and
  Norwegian text and shorter interface labels where needed.

Fixed

• Corrected TCAM backup-battery response handling on CMA vehicles. The change was
  verified on a connected Polestar 2.
• Battery certificates no longer pass when required measurements are missing.
  Cell comparisons appear only when the required cell data was collected, and
  missing measurements use consistent labels.
• Reaching a configured scan limit no longer appears as a cable or vehicle
  communication failure.
• Fixed vehicle-wide requests occasionally missing very fast module responses.
• A failed first recovery step no longer closes a diagnostic session that can
  still recover.
• Restored missing battery, fault-code, ECU inventory, and parasitic-drain data
  in exports, and fixed imports of affected saved sessions.
• Fixed modules that could not be selected in scan-scope controls.
• Fixed software-capability checks that could stop before contacting the
  vehicle.
• Empty module responses are now reported as unavailable instead of being
  decoded as current measurements.
• Corrected radar and module mappings, incomplete-reply handling, stored scan
  results, cancellation during long operations, connection recovery, and
  service-status reporting.

Reliability and safety

• Operations that can change vehicle state remain protected by safety checks.
• Functions without enough verification on real vehicles remain disabled or
  carry an explicit unverified status.
• Missing and unsupported values remain unavailable instead of being replaced
  with assumed results.

Release v0.2.0

Changelog

This is a beta. Handle it with care. Fault code clearing and service modes are active. That doesn't mean the app will work on your vehicle or model, or that you should run these functions. Handle with care, There will be bugs.

Vehicle diagnostics

New vehicle capabilities view

Hanterill can now show more information about what a connected vehicle supports.

The new Capabilities view combines live vehicle information with Hanterill's diagnostic knowledge to show:

• supported vehicle features
• available diagnostic areas
• service-related capabilities
• known vehicle configuration information
• software compatibility information
• diagnostic reference information

Where Hanterill cannot determine something reliably, it now shows the result as unknown instead of guessing.

---

Vehicle profile

The Vehicle screen now includes a more detailed vehicle profile.

Depending on what the vehicle exposes, this can include information such as:

• vehicle configuration
• equipment information
• platform details
• software-related information
• factory configuration data

Missing information is shown as unavailable instead of being filled with assumptions.

---

Service status

A new Service Status area has been added.

It provides read-only diagnostic information for systems including:

• driver assistance
• cameras and radar
• steering
• braking
• climate control
• safety systems
• body systems
• service-related functions

Some reference values are shown as raw diagnostic data when their meaning cannot yet be decoded safely. Hanterill prefers a raw value over a guessed interpretation.

---

Engine live data

A new Engine screen provides live information for combustion and plug-in hybrid vehicles.

Available information can include:

• coolant temperature
• oil temperature
• oil level
• fuel level
• fuel-pump status
• fuel-pump activity
• particulate-filter information
• regeneration status
• transmission temperature
• transmission adaptation information
• 48V battery state of charge

Values with a known and trusted interpretation are decoded automatically. Values that are not yet understood remain visible as raw data instead of being guessed.

This is based on data from the V90 T6 and XC40 T5. It might not fit your car.

---

ICE and plug-in hybrid support

Hanterill now includes a dedicated reference layer for combustion and plug-in hybrid vehicles.

This brings more diagnostic knowledge into the application without mixing unverified information into the trusted diagnostic catalogue.

The new reference information covers areas such as:

• engine
• transmission
• emissions systems
• fuel system
• hybrid systems
• temperature monitoring
• vehicle status information

This reference data comes from the V90 T6 and XC40 T5 and stays separated from verified vehicle data until it's confirmed on a matching vehicle.

This means Hanterill can expand support while still clearly distinguishing between:

• verified diagnostics
• experimental diagnostics
• reference-only information
• unsupported information

---

Vendor diagnostic reference catalogue

Hanterill now includes a much larger DTC reference catalogue.
It contains information for more than:

• 100 vehicle modules
• 120 diagnostic address groups
• 20,000 diagnostic identifiers

This information powers several new features throughout the application, including:

• engine live data
• vehicle capabilities
• service status
• vehicle profile
• diagnostic browsing
• software compatibility checks

The catalogue is sanitized before it becomes part of Hanterill. Sensitive or inappropriate source information is excluded.

---

Battery diagnostics

Expanded multi-platform support

Battery diagnostics now understand multiple vehicle architectures instead of assuming one battery design.

Supported or partially supported platforms now include:

• CMA
• SPA
• SEA1
• SPA2

Hanterill can adapt its battery interpretation depending on the vehicle platform and battery layout.

---

More battery layouts

Hanterill now understands several different battery layouts used across Volvo, Polestar, and related platforms.

This includes:

• long-range EV packs
• standard-range EV packs
• plug-in hybrid battery packs
• alternative cell and module layouts
• different physical module locations

The UI no longer assumes that every vehicle uses the same number of cells or the same battery shape.

---

Better battery health handling

Battery State of Health can now be interpreted correctly across more vehicle platforms.

Different platforms expose battery health differently, so Hanterill now uses the correct decoding method for the detected architecture instead of applying one format everywhere.

---

Battery thermal exposure

The Battery screen now includes lifetime thermal exposure information when supported by the vehicle.

It can show:

• time spent in different temperature ranges
• total recorded operating time
• how much time the battery has spent in a preferred temperature range
• an overall thermal-stress indication

This gives a better long-term picture of how the battery has been treated.

---

Cell voltage comparison

Battery cell snapshots can now be compared offline.

Two captures can be loaded and compared without reconnecting to the vehicle.

The comparison highlights:

• voltage changes per cell
• changes in total cell spread
• cells that are drifting away from the rest of the pack

This is useful for identifying changes over time.

---

Retry missing battery modules

A battery-cell scan no longer has to be restarted completely when only a few modules fail.

A new retry option reads only the modules that were missing or timed out, while preserving the successful results.

---

Better battery consistency checks

Hanterill now performs additional checks between pack-level and cell-level data.

These include comparisons of:

• individual cell health
• overall pack health
• cell state-of-charge consistency
• cell capacity consistency

This helps surface suspicious or inconsistent readings.

---

Better battery-pack visualization

The cell detail view now understands the physical location of cells and modules across different battery layouts.

Instead of simply showing a cell number, Hanterill can provide more useful context about where that cell sits within the physical pack.

---

Live telemetry

Periodic live data

Hanterill can now request live data as a continuous stream instead of reading every value individually.

This enables smoother live telemetry and more efficient recording.

Several sampling speeds are supported depending on the diagnostic function and vehicle.

---

Live telemetry recording

Live telemetry sessions can now be recorded directly in Hanterill.

Recorded sessions can later be opened and replayed without a vehicle connected.

---

Playback controls

The Live screen now includes playback controls for recordings.

You can:

• play
• pause
• scrub through the timeline
• change playback speed
• select which channels to display
• export the recording

Playback speeds include:

• normal speed
• 2×
• 5×

---

External recording import

External Hanterill recording files can now be loaded into the Live screen.

This makes it possible to share, archive, and inspect diagnostic recordings offline.

---

Improved live workspace

The recordings drawer now includes both:

• previously saved recordings
• recordings created during the current session

This fixes the previous disconnect between the live workspace and stored session data.

---

ECU discovery

Faster module discovery

Initial ECU discovery is now much faster.

Instead of contacting every module one by one, Hanterill can discover multiple responding modules using a single request.

During live testing, more than 20 modules were discovered in well under one second. This reduces connection and inventory time.

---

Quiet-module discovery

Some vehicle modules do not respond during normal discovery.

Hanterill now includes a deeper multi-stage discovery process for these modules.

It can check:

• whether the module exists
• whether it allows an extended diagnostic session
• whether identification information is available
• whether diagnostic faults can be queried
• how accessible the module is

Each module is then classified. For example:

• not fitted or silent
• present but limited
• fully accessible for diagnostics

The process includes cancellation and per-module progress.

New park-...

Release 0.1.1

Hanterill 0.1.1

Released: September 11, 2026

This is a large update focused on broader vehicle support, faster diagnostics, better battery analysis, improved reliability, and a more complete desktop experience.

Highlights

• Early support for Volvo SPA1 vehicles, including selected hybrids and EVs
• Early support for SEA-based vehicles, including Volvo EX30, Polestar 4 and selected Zeekr models
• New Pre-Purchase Inspection scoring and reporting
• Faster vehicle discovery and ECU scanning
• Expanded battery, charging, climate and power diagnostics
• Major reliability improvements
• Improved privacy when exporting reports and support data

Important: SPA1 and SEA support is currently experimental. Only selected diagnostic functions are available and many vehicles, ECUs and data points are not yet supported. CMA vehicles such as the Polestar 2 remain the most complete platform in Hanterill.

New Vehicle Support

Volvo SPA1

Initial support has been added for Volvo SPA1 vehicles, including selected hybrid and electric models.

Depending on the vehicle, Hanterill can now begin identifying and reading information such as:

• Battery State of Health
• Battery State of Charge
• Battery voltage
• Battery temperatures
• Cell voltage information
• High-voltage system status
• Charging information
• Battery power limits

Support varies significantly between models and model years.

SEA

Initial support has also been added for vehicles based on the Sustainable Experience Architecture, including:

• Volvo EX30
• Polestar 4
• Zeekr 001
• Zeekr X
• Zeekr 009

SEA support is still at an early stage. Vehicle detection, ECU discovery and selected diagnostic readings are being introduced first, with broader support planned as more vehicles are tested.

Battery Diagnostics

Battery diagnostics have been expanded to better support different battery layouts across CMA, SPA and SEA vehicles.

Hanterill can now adapt its battery analysis to different pack configurations instead of assuming every vehicle uses the same cell layout.

Battery-related improvements include:

• Improved cell voltage analysis
• Battery temperature visualization
• Better pack balance calculations
• Battery degradation assessment
• Support for additional battery layouts
• Improved handling of incomplete or unsupported battery data

The Battery Health experience now avoids presenting uncertain data as confirmed values.

Pre-Purchase Inspection

A new Pre-Purchase Inspection (PPI) system has been added.

Hanterill can evaluate multiple areas of the vehicle and produce an overall condition assessment based on available diagnostic data.

The inspection can include:

• Battery health
• Battery degradation
• Cell voltage balance
• Mileage consistency
• Service information
• Battery temperature consistency
• Electrical system health

Historical inspection reports can also be recalculated using newer inspection rules as Hanterill improves.

Faster Vehicle Scanning

Vehicle discovery and ECU scanning have been significantly improved.

Hanterill can now query multiple modules more efficiently instead of waiting for every ECU individually.

This results in:

• Faster ECU discovery
• Faster full vehicle scans
• Shorter waits for modules that are not installed
• Better handling of unavailable ECUs
• Improved reconnect behavior
• Better reuse of information learned from previous scans of the same vehicle

Previously detected vehicle information can now help later sessions complete faster.

Smarter Diagnostic Reads

Hanterill has become more conservative about interpreting diagnostic data.

If a vehicle returns unexpected or incomplete information, Hanterill will now prefer to show the value as unsupported or uncertain rather than guessing.

It can also remember which readings are supported by a particular ECU, reducing unnecessary requests during future sessions.

This should result in:
