Vehicle Collision Detection

WARNING: This page is about a different variant/trim than selected.

As a safety precaution, the Starter/Generator Control Module monitors the collision event messages from the Inflatable Restraint Sensing and Diagnostic Module (SDM). This message is broadcast by the SDM via serial data to inform various control module that a collision event has occurred so they can take appropriate action. This message does not indicate the severity of the collision, nor does it indicate that airbag deployment has been commanded.

If a collision event message is received by the Starter/Generator Control Module, it will enter a collision event detected state and respond by opening the high voltage contactors. This will help isolate the high voltage battery from the rest of the vehicle and reduce the possibility of a compromised high voltage system creating a hazard.

If the Starter/Generator Control Module has entered the collision event detected state, the High Voltage System Inspection , procedure must be performed to ensure the high voltage system has not been compromised. If compromised, any necessary repairs should be made. The collision event detected condition will remain active until cleared using the Clear Secured High Voltage DTCs .
