Post Crash Alert Function
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The post crash alert is a function controlled by the Body Control Module (BCM). If the RCM determines that an impact of a pre-determined severity (the air bags may or may not be deployed) has occurred, the RCM sends a message to the BCM over the High Speed Controller Area Network (HS-CAN) and the post crash alert function is activated. The post-crash alert function activates the hazard lamp function and cycles the horn on 3 times, then off for 4 seconds, and repeats this cycle until the battery is discharged or the function is turned off. The post crash alert function can be turned off by:
- pressing the hazard flasher lamp switch (which may need to be pressed more than once).
- pressing the Remote Keyless Entry (RKE) transmitter UNLOCK button.
- pressing the RKE transmitter PANIC button.
