Antilock Brake System (ABS) Hydraulic Control Module
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 (2) at the hydraulic con-
trol unit.
(Tighten: Brake tube nuts to 10 N·m)
5. Disconnect the ABS module electrical connector
(1).
6. Remove the mounting bolts (3) 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 module and bleed the brake system (See
Antilock Brake System (ABS) Bleeding Procedure in Section 12 Brakes).
