Tesla CAN Red Light Stop

TeslaCanTrafficStop

Default OFF; restart required. Tesla Model 3/Y with active openpilot longitudinal control only: fresh APP_trafficControl red and a stop line below 126 m supplement existing stops. Supports only the 8-byte, metre-scale, vision-backed profile; rejects 6-byte DAS_road. Green releases only this constraint. Late red may exceed braking capability; lost/inconsistent signals request takeover and the existing soft-disable. Other obstacles and manual stops remain. Verify the vehicle protocol/distance reference and validate on a closed course; not road acceptance.

Behavior

ON supplements stops on Tesla Model 3/Y with active openpilot longitudinal control; OFF preserves existing behavior. Three unique red samples spanning 0.2 seconds and a positive line distance below 126 m admit a constraint in ACC or blended; green needs three same-target samples spanning 0.5 seconds and releases only this constraint. Active CAN stops temporarily use ACC solving in blended, retain stronger model braking and restore the selected mode on release.

Usage

Restart after changing. Independent of turn lamps, Share Data and Signal Assist. Only the exact 8-byte, metre-scale, vision-backed APP_trafficControl profile qualifies; six-byte DAS_road is rejected. Pedal input suppresses this feature until disengagement and new engagement. Other brands ignore the switch.

Reference

Verify raw vehicle CAN, direction relevance and the provisional 2 m stop buffer on a closed course before use. Late red can exceed braking capability. Signal loss after 0.5 seconds or target inconsistency requests takeover and soft-disable, which ultimately disengages; the driver must brake. No new Panda permission or road acceptance.
