Parking Brake (G2298411): Overview

The EPB  is an electrically actuated system that operates the calipers on the rear brakes. The system consists of:

• An EPB  switch
• The EPB  actuators (quantity 2)
• The warning indicators (quantity 2)
• The ABS  .

The vehicle can have different components installed if it is a PHEV  , MHEV  or a conventional drive line. The PHEV  and MHEV  will have an Integrated Power Brake system which contains the ABS  functionality. Non PHEV  and MHEV  vehicles may have a separate ABS  installed.

The EPB  is controlled by the ABS  , 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  . 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  . The signals are transmitted on the High Speed (HS) Controller Area Network (CAN) chassis systems bus and FlexRay.
