Brake System

The IPC provides brake system displays for low brake fluid level, parking brake applied and ABS concerns that display along with the brake warning indicator operation.

When the parking brake is applied, the BCM sends the parking brake warning indicator request message to the GWM over the HS-CAN1. The GWM sends the parking brake warning indicator request message to the IPC over the HS-CAN3 to illuminate the brake warning indicator. Once the parking brake warning indicator request message has been received and the brake warning indicator illuminated with the vehicle in motion, the parking brake warning message is displayed. If the condition is not corrected, the IPC sounds the parking brake warning chime along with the brake warning indicator and the parking brake message center message display.

When a low brake fluid level condition exists, the BCM sends the brake fluid level warning message to the GWM over the HS-CAN1. The GWM sends the brake fluid level warning 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 concern exists, the ABS module sends the brake (red) warning indicator request message to the GWM over the HS-CAN1. The GWM sends the brake (red) warning indicator request message to the IPC over the HS-CAN3 to illuminate the ABS warning indictor, brake warning indicator and to turn on the traction control off message in the message center.
