Hydraulic Control Assembly - Antilock Brakes: Description and Operation
Integrated Control Unit (ICU)
MK25
INTEGRATED CONTROL UNIT - MK25
DESCRIPTION
The hydraulic control unit (HCU) and the controller antilock brake (CAB) used with this antilock brake system are combined (integrated) into one
unit, which is called the integrated control unit (ICU) (Fig. 10). The ICU is located below the master cylinder in the engine compartment. It is mounted
to the left frame rail.
The ABS ICU consists of the following components: the CAB, eight (build/decay) solenoid valves (four inlet valves and four outlet valves) and one
hydraulic pump motor.
The ABS ICU with traction control consists of the following components: the CAB, eight (build/decay) solenoid valves (four inlet valves and four
outlet valves), two master cylinder isolation valves, two low pressure feed valves and one hydraulic pump motor.
The replaceable components of the ICU are the HCU and the CAB. No attempt should be made to service any individual components of the HCU or
CAB.
