Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Post-Crash Alert Function
The post-crash alert is a function controlled by the BCM. If the RCM determines an impact of enough severity has occurred (the airbags may or may not be deployed), the post-crash alert function activates.
The post-crash alert function:
- sounds the horn.
- turns on the hazard lights.
- turns on the interior lights.
- unlocks the doors.
The post-crash alert function can be turned off by:
- pressing the hazard flasher lamp switch (which may need to be pressed twice).
- pressing the transmitter unlock button.
- pressing the RKE transmitter PANIC button.
- cycling the ignition (RUN-OFF-RUN-OFF-RUN).
- opening the driver door.
