Removal & Installation
NOTE :
The following special tools are required to perform the repair procedure:
•Diagnostic Scan Tool X-431
NOTE :
The ABS hydraulic control module is comprised of the Hydraulic Control Unit (HCU) and the Electronic Control Unit
(ECU). These are serviced as a complete unit and cannot be serviced separately. 1. Disconnect the negative battery cable.
2. Turn the ignition switch off.
3. Using a brake pedal holding tool, depress the brake pedal past its first 25 mm of travel and hold it in this posi- tion. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to
drain out of the master cylinder reservoir while the lines are disconnected.
4. Remove the brake tubes (1) at the hydraulic con- trol unit.
(Tighten: Brake tube nuts to 10 N·m)
5. Disconnect the ABS hydraulic control module elec- trical connector.
6. Remove the mounting bolts attaching the HCU mounting bracket to vehicle.
(Tighten: ABS mounting bracket bolts to 20 N·m)
7. Position the brake tubes as necessary without bending them.
8. Remove the ABS HCU from vehicle.
9. Remove the ABS mounting bolts and mounting bracket as necessary. (Tighten: ABS mounting bolts to 10 N·m)
10. Installation is in the reverse order of removal.
Installation Notes:
• After installation, connect the X-431 scan tool to initialize the ABS hydraulic control module and bleed the brake
system (See Antilock Brake System (ABS) Bleeding Procedure in Section 12 Brakes).

A/C System Performance
The ambient air temperature must be a minimum of 21°C for this test.1. Connect a manifold gauge set.
2. Set the A/C Heater mode control switch knob in the Panel position, the temperature control knob in the full cool position, the A/C button in the On position, and the blower motor switch knob in the highest speed position.
3. Start the engine and hold the idle at 2,000 RPM with the compressor clutch engaged.
4. The engine should be at operating temperature. The doors and windows must be open.
5. Insert a thermometer in the driver side center A/C (panel) outlet. Operate the engine for five minutes.
6. The compressor clutch may cycle, depending upon the ambient temperature and humidity.
7. With the compressor clutch engaged, record the discharge air temperature and the compressor discharge pres- sure.
8. Compare the discharge air temperature to the performance temperature and pressure chart.
NOTE :
The discharge air temperatures will be lower if the humidity is less than the percentages shown.

Diagnostic Help
1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronicmodules through the data network.
2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.
3. If the DTC cannot be deleted, it is a current fault.
4. Use a digital multimeter to perform voltage readings on electronic systems.
5. Refer to any Technical Bulletins that may apply to the failure.
6. Visually inspect the related wiring harness.
7. Inspect and clean all Restraints Control Module (RCM) grounds that are related to DTC.
8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage supply circuits that may apply to the DTC.
Intermittent DTC Troubleshooting
If the failure is intermittent perform the following:
•Check for loose connectors.
• Look for any chafed, pierced, pinched, or partially broken wires.
• Monitor the scan tool data relative to this circuit.
• Wiggle the related wiring harness and connectors while looking for an interrupted signal on the affected circuit.
• If possible, try to duplicate the conditions under which the DTC set.
• Look for the data to change or for the DTC to reset during the wiggle test.
• Look for broken, bent, pushed out or corroded terminals.
• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age, foreign material.
• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.
• Remove the Restraints Control Module (RCM) from the troubled vehicle and install in a new vehicle and test. If
the DTC cannot be deleted, the RCM is malfunctioning. If the DTC can be deleted, return the RCM to the origi-
nal vehicle.
Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connec-
tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted
resistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically
affect an electronically controlled circuit. A poor or corroded ground can affect the circuit. Perform the following when
inspecting a ground connection:
1. Remove the ground bolt or screw.
2. Inspect all mating surface for tarnish, dirt, rust, etc.
3. Clean as required to assure good contact.
4. Reinstall bolt or screw securely.
5. Inspect for add-onaccessories which may be interfering with the ground circuit.
6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, make
sure no excess wire insulation has been crimped creating a bad ground.
Diagnostic Tools
Diagnostic Scan Tool X-431
Read the following when connecting the X-431 scan tool:
•Connect the scan tool to the Data Link Connector (DLC) for communication with the vehicle.
• The DLC is located on the driver side compartment under the steering column (it is attached to the instrument
panel and accessible from the driver seat).
• The DLC is rectangular in design and capable of accommodating up to 16 terminals.
• The electrical connector has keying features to allow easy connection.
