Parking Brake (G2164833): Overview

The Electric Park Brake (EPB) is an electrically actuated system that operates the calipers on the rear brakes. The system consists of:

• An EPB switch
• 2 EPB actuators
• Clutch pedal position sensor (manual transmission vehicles only)
• 2 warning indicators
• Anti-lock Brake System (ABS) control module

The EPB is controlled by the ABS control module, which uses the EPB actuators to apply and release the rear disc brakes. Operation of the EPB is initiated by the EPB switch and software within the ABS control module. The EPB has the following operating modes:

• Static apply/release
• Ignition off apply (manual transmission vehicles only)
• Drive away release
• Automatic transmission apply/release
• High temperature reclamp
• Driver exit warning
• Dynamic apply
• Roll away reclamp

Signals from other vehicle systems for operation of the EPB are transmitted to the ABS control module on the High Speed (HS) Controller Area Network (CAN) powertrain systems bus.
