Brake System Message Displays

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

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

When the parking brake is applied, the BCM sends the parking brake status to the GWM over the High Speed Controller Area Network 1 (HS1-CAN). The GWM gateways the message to the IPC over the High Speed Controller Area Network 3 (HS3-CAN) to illuminate the brake warning indicator and turn on the parking brake applied message in the message center.

When a low brake fluid level condition exists, the BCM sends the brake fluid level low message request to the GWM over the High Speed Controller Area Network 1 (HS1-CAN). The GWM gateways the message to the IPC over the High Speed Controller Area Network 3 (HS3-CAN) 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 High Speed Controller Area Network 2 (HS2-CAN). The GWM sends the brake (red) warning indicator request message to the IPC over the High Speed Controller Area Network 3 (HS3-CAN) to illuminate the ABS warning indictor and to turn on the check brake system message center warning display.
