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 air bags 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 all the doors and liftgate/cargo doors (if locked at impact with key in the ignition).
- turns off the wipers, if on.
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 switch (RUN-OFF-RUN-OFF-RUN).
