Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Integrated Control Unit
- 1 - Anti lock brake module.
- 2 - Hydraulic control unit.
- 3 - Pump/motor.
The hydraulic control unit (2) and the anti-lock brake module (1) used with this anti-lock brake system are combined (integrated) into one unit, which is called the integrated control unit.
The ICU (2) is located in the engine compartment, mounted on a bracket attached to the left side of the front suspension crossmember.
The ABS with ESP and all-speed traction control ICU consists of the following components: The ABM, 8 (build/decay) solenoid valves, two traction control solenoid valves, two electronic 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. The ABM can be serviced without removing the entire assembly from the vehicle.
For additional information on the ABM. Refer to ANTI-LOCK BRAKE SYSTEM WITH ELECTRONIC STABILITY PROGRAM .
The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain components may also reference ESP, ESC, or use the traction control symbol.
