Brake Warning Indicator

The brake warning indicator informs the driver the brake fluid level is low, there is a failure in the base brake system or the electric park brake is applied. The IPC uses 3 messaged inputs to control the brake warning indicator.

The IPC receives the brake (red) warning indicator request, the brake warning indicator request and the red brake warning indicator request from the GWM over the HS-CAN3.

The GWM receives the brake (red) warning indicator request and the brake warning indicator request from the ABS module over the HS-CAN2.

The GWM receives the red brake warning indicator request from the BCM over the HS-CAN1.

Refer to ABS/Brake/Stability-Traction Control System Indication description for information on the conditions when the brake warning indicator is turned on.
