Brake System

The IPC provides brake system messages for the following concerns and status:

• Low brake fluid level.
• Electric parking brake status and faults
• ABS concerns that display along with the brake warning indicator operation.

When the electric park brake is selected, the ABS module sends the brake lamp request and park brake (red) warning indicator request to the GWM over the HS-CAN2. The GWM sends the brake lamp request and park brake (red) warning indicator request to the IPC over the HS-CAN3 to illuminate the brake warning indicator and display the electric parking brake messages.

When a low brake fluid level condition exists, the ABS module sends the brake lamp request message request to the GWM over the HS-CAN1. The GWM sends the message to the IPC over the HS-CAN3 to illuminate the brake warning indicator and turn on the brake fluid level low message in the message center.

When an ABS or parking brake system concern exists, the ABS module sends the brake (red) warning indicator request message to the GWM over the HS-CAN2. The GWM sends the brake (red) warning indicator request message to the IPC over the HS-CAN3 to illuminate the ABS warning indictor and to turn on the check brake system message center warning display.
