NOTE: Later launch vehicles use the MK25E Antilock Braking System (ABS). The MK25E ICU can be easily identified by the brake tube ports on two sides as shown in Fig 1 instead of on one side as used on previous systems.

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 a bracket that is attached to the right side rail through the use of isolation grommets (2).

The ABS with traction control ICU consists of the following components: the ABM, eight (build/decay) solenoid valves (four inlet valves and four outlet valves), two traction control solenoid valves, two hydraulic 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.

For additional information on the ABM, (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES/ANTILOCK BRAKE MODULE - DESCRIPTION) .
