Brake System Message Displays

The IPC provides brake system displays for low brake fluid level, parking brake status and ABS concerns that supplement the brake warning indicator operation.

When the parking brake is applied, the BCM sends the park brake warning request to the IPC over the Medium Speed Controller Area Network (MS-CAN) to illuminate the brake warning indicator and display the parking brake applied message in the message center.

When a low brake fluid level condition exists, the BCM sends the brake fluid level warning request to the IPC over the Medium Speed Controller Area Network (MS-CAN) to illuminate the brake warning indicator and display the brake fluid level low message in the message center.

When an ABS concern exists, the ABS module sends the brake warning indicator request message to the GWM over the HEV - CAN. The GWM sends the brake warning indicator request message to the IPC over the Medium Speed Controller Area Network (MS-CAN) to illuminate the ABS warning indictor and to display the check brake system warning message in the message center.
