This release exists to collect data
BETSY can read the five INF detail tables off the HV ECU, but it cannot yet tell you what a
sub-code means. It ships no bit-to-code mapping, because nothing in the data collected so far
supports one: every byte seen so far has been zero, on a healthy car.
That is what this release is for. If your Gen2 Prius has a fault stored, the triangle on, a
P0AA6, P3000, P3019 or anything else, a capture from it is the one thing that can finish
this. It takes about two minutes:
- Install the APK below
- Connect your ELM327 adapter
- Open DTC / INF codes and let the scan finish
- Tap SHARE THIS SCAN
No account, no sign-up. The app shows you exactly what it sends before it sends anything, and
captures land publicly in captures/.
Healthy car? Send it too. Those are the control group: they prove the read works across
different adapters and model years, which is what lets a faulty car's result be trusted.
What it does today
A working battery scanner, whatever happens with the sub-codes:
- Live pack data: state of charge, current, per-block voltages, internal resistance, temperatures
- Hybrid trouble codes, read from both ECUs
- The five INF detail tables, captured raw
Confirmed on a stock US-market 2009 Prius with a $3.50 ELM327 v1.5 clone.
Notes
Read-only. This app never clears a code, runs an actuator test, or writes to an ECU.
Sideload build. Android will warn about installing from an unknown source; that is expected for
anything not distributed through a store.
