Parking Brake - Overview

Overview 

The parking brake system uses 2 switch activated, Electronic Control Unit (ECU) controlled motors to apply and release the rear brake calipers. The ABS 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 and when the parking brakes are applied and released.
