Description

DESCRIPTION





The Hydraulic Control Unit (HCU) (2) and the Antilock Brake Module (ABM) (1) used with this antilock brake system are combined (integrated) into one unit, which is called the Integrated Control Unit (ICU).





The ICU (1) is located in the engine compartment, mounted to the right side body frame rail near the strut tower.

Two different ICU's are used on this vehicle depending on whether or not the vehicle is equipped with traction control and Electronic Stability Program (ESP(R)). The HCU on a vehicle equipped with traction control or ESP(R) has a valve block that is approximately one inch longer than a HCU on a vehicle that is equipped with ABS only.

The ABS-only ICU consists of the following components: the ABM, eight (build/decay) solenoid valves (four inlet valves and four outlet valves), valve block, fluid accumulators, a pump, and an electric motor.

The ABS with ESP(R) and All-Speed Traction Control ICU consists of the following components: the ABM, eight (build/decay) solenoid valves, two traction control solenoid valves, two shuttle valves, valve block, fluid accumulators, a pump, and an electric pump/motor.

The replaceable components of the ICU are the HCU and the ABM. No attempt should be made to service any components of the HCU or ABM.
