Parking Brake - Overview: Overview

The parking brake system uses 2 switch activated, ECU controlled motors to apply and release the rear brake calipers. The EPB module controls and monitors the parking brake system and sets Diagnostic Trouble Codes (DTCs) when a fault is present in the system. The IPC illuminates the parking brake warning indicator and displays a message in the message center when a fault is present, when the parking brakes are applied and when they are released.
