Action Taken When the DTC Sets
C0186 5A, C0186 71, C0196 00, C0196 5A, and C019B 5A
* The EBCM disables the stability control for the duration of the ignition cycle.
* The traction control/stability control-active indicator turns ON.

The EBCM disables the hill start assist for the duration of the ignition cycle.
Conditions for Clearing the DTC
* A current DTC clears when the diagnostic runs and passes.
* The EBCM will turn OFF the indicator in the next ignition cycle.
Diagnostic Aids
DTC C0186 and C0287 may set after replacing the Multi-Axis Acceleration Sensor if the sensor is not configured and setup. Perform the
Multi-Axis Acceleration Sensor Module Programming and Setup (See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Yaw Rate Sensor/Testing and Inspection/Multi-Axis Acceleration Sensor Module Programming and Setup) and the Vehicle Yaw Sensor
Learn (See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Yaw Rate Sensor/Testing and Inspection/Vehicle Yaw
