Description
The ABS module uses information received from several sensors (wheel speed sensors, steering wheel rotation sensor, stability control sensor cluster, etc.) to determine if a vehicle instability event is about to occur. If an event is going to occur, the ABS module will adjust brake torque at specific wheels and the Powertrain Control Module (PCM) will reduce engine torque to make the vehicle more stable. Once the ABS module has determined that the stability event has been corrected, it will return brake and engine torque to normal and continue to monitor the vehicle. The ABS module monitors the stability event and is programmed to set DTC C1996 and disable the stability control system if the stability event lasts longer than 15 seconds.
