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 replacement of the ABM, refer to REMOVAL .

CAUTION: For Adaptive Cruise Control (ACC) equipped vehicles, the ABM and HCU are not separately serviceable. They must be replaced as an assembly.

For additional information on the ABM, refer to DESCRIPTION .
