Antilock Brake System (ABS) Bleeding Procedure
ABS Bleeding Information
WARNING!
When bleeding the brake system, wear safety glasses. A clear bleed tube must be attached to the bleeder
screws and submerged in a clear container filled partially. Direct the flow of brake fluid away from yourself and
the painted surfaces of the vehicle. Brake fluid at high pressure may come out of the bleeder screws when
opened.
CAUTION:
Before removing the master cylinder cap, wipe it clean to prevent dirt and other foreign matter
from dropping into the master cylinder reservoir. Use brake fluid or an equivalent from a fresh,
tightly sealed container. Brake fluid must conform to DOT 4 specifications.
NOTE :
During the brake bleeding procedure, be sure the brake fluid level remains close to theMAXlevel in the master
cylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add brake fluid as
required.
NOTE :
Do not pump the brake pedal at any time while having a bleeder screw open during the bleeding process. This will
only increase the amount of air in the system and make additional bleeding necessary. Do not allow the master
cylinder reservoir to run out of brake fluid while bleeding the system. An empty reservoir will allow additional air into
the brake system. Check the fluid level frequently and add fluid as needed. The following wheel circuit sequence for
bleeding the brake hydraulic system should be used to ensure adequate removal of all trapped air from the hydraulic
system.
ABS Bleeding Instructions
When bleeding the ABS system, the following bleeding sequence must be followed to ensure complete and adequate
bleeding:
1. Make sure all hydraulic fluid lines are installed and properly torqued.
2. Connect the X-431 scan tool to the diagnostics connector.
3. Using the scan tool, check to make sure the ABS module does not have any fault codes stored. If it does, clear them.
4. Bleed the base brake system (See Manual Brake Bleeding in Section 12 Brake).
NOTE :
Pressure bleeding is recommended to bleed the base brake system to ensure all air is removed from the brake
system.
5. Using the scan tool, access ABS bleedingfunction. Follow the instructions displayed. When finished, discon-
nect the scan tool and proceed.
6. Bleed the base brake system a second time. Check brake fluid level in the reservoir periodically to prevent emptying, causing air to enter the hydraulic system.
7. Fill the master cylinder fluid reservoir to the MAXlevel.
8. Test drive the vehicle to be sure the brakes are operating correctly and that the brake pedal does not feel spongy.

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).
Front Wheel Speed Sensor
Removal & Installation
1. Disconnect the negative battery cable.
2. Raise and support the vehicle.
3. Remove the wheel mounting nuts and the tire and wheel assembly.
(Tighten: Wheel mounting nuts to 110 N·m)
4. Disconnect the wheel speed sensor electrical connector.

Parking Brake Lever
Removal & Installation
1. Block the tire and wheel assemblies so the vehicle does not move once the vehicle parking brake lever isreleased.
2. Remove the center console (See Center Console Removal & Installation in Section 15 Body & Accessories).
3. Loosen the adjusting nut (2) on the lever’s output cable, taking tension off parking brake cables.
4. Back the nut off until it is flush with the end of the output cable.
5. Remove the bolts (1) attaching the parking brake lever to the vehicle.
(Tighten: Parking brake lever bolts to 30 N·m)
6. Remove the parking brake assembly.
7. Installation is in the reverse order of removal.
Installation Notes:
• After installation, adjust the parking brake cable as necessary (See Parking Brake Adjustment in Section 12
Brakes).
