Output Test performed on Airbag Control Module (J234) or Control Module for Central Locking (J429)
Vehicle involved in Accident
- Airbag Control Module (J234) stored Crash Data
Incorrect or faulty Emergency Flasher Switch (E3)
Wiring/Connectors from/to Airbag Control Module (J234) faulty

Check/clear Fault Codes
Check fitment and wiring/connectors from/to Emergency Flasher Switch (E3)
- See Special Notes
Check wiring/connectors from/to Airbag Control Module (J234)

Some vehicles use a crash signal wire from the airbag module to trigger post-crash activity such as shutting down the engine, turning on the interior lights, unlocking the doors, and turning on the emergency flasher (hazard) lights. A failed or incorrect Emergency Flasher Switch (E3) has occasionally been found to raise the crash signal on its own, triggering unexpected post-crash behavior from other modules that monitor the crash signal wire, such as the ECU or CCM/BCM. To verify, temporarily disconnect Emergency Flasher Switch (E3), clear codes and re-test for expected behavior.
