Caution: To help avoid personal injury, due to a retained load on the brake modulator, the Gear Tension Relief function of the scan tool must be performed prior to removal of the ABS brake modulator/master cylinder assembly.

1. Use the Scan Tool in order to perform the Gear Tension Relief Sequence.
2. Disconnect two brake solenoid valve electrical connectors (1), (3).
3. Disconnect the brake fluid level indicator sensor connector (2).
4. Disconnect the ABS brake motor pack electrical connector (6).
5. Remove four brake pipes (5).
6. Remove the two nuts (8) attaching the ABS brake modulator/master cylinder assembly (7) to the vacuum booster.
7. Remove the ABS brake modulator/master cylinder assembly (7).

1. Install the ABS brake modulator/master cylinder assembly (7) into the vehicle.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the two nuts (8) attaching the ABS modulator/master cylinder assembly (7).

Tighten
Tighten the ABS brake modulator/master cylinder nuts (8) to 27 N·m (20 lb ft).

3. Install four brake pipes (5) onto the ABS brake modulator/master cylinder assembly (7).

Tighten
Tighten the tube nuts to 24 N·m (18 lb ft).

4. Connect the ABS brake motor pack electrical connector (6).
5. Connect the brake fluid level indicator sensor electrical connector (2).
6. Connect two brake solenoid valve electrical connectors (1), (3).

Important: Bleed the system. Refer to Bleeding Brake Hydraulic System.

7. Perform the Diagnostic System Check
