1. Remove the brake modulator assembly. Refer to Brake Pressure Modulator Valve Assembly Replacement .
2. Remove the Torx® head screws (5) attaching the gear cover (4).
3. Remove the gear cover (4).
4. Remove the four Torx® head screws (6) attaching the motor pack (1) to the brake modulator (2).
5. Remove the motor pack (1) from the brake modulator (2).
6. Remove the Torx® head screws that retain the proportioning valve.
7. Remove the proportioning valve.

Important: When replacing the ABS brake modulator, install the three gears in the same location on the replacement brake modulator. Refer to Brake Modulator Gear Replacement .

Important: A new gasket MUST be used when installing the Proportioning Valve.

1. Install the proportioning valve to the hydraulic modulator.

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 Torx® head screws that retain the proportioning valve to the hydraulic modulator.

Tighten
Tighten the Torx® head screws to 12 N·m (106 lb. in.).

3. With the ABS brake modulator positioned upside down, and the gears facing you, rotate each ABS brake modulator gear clockwise until movement stops.

The procedure causes the following conditions:

•	The pistons are positioned very close to the top of the modulator bore.

•	The brake bleeding procedure is simplified.

4. Install the ABS brake motor pack (1) onto the brake modulator assembly (2).

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.

5. Install the four Torx® head screws (6) that retain the motor pack (1) to the brake modulator (2).

Tighten
Tighten the four Torx® head screws to 5 N·m (44 lb. in.).

6. Install the gear cover (4) to the brake modulator assembly (2).
7. Install the Torx® head screws (5) that retain the gear cover (4).

Tighten
Tighten the Torx® head screws to 4 N·m (36 lb. in.).

8. Install the brake modulator assembly. Refer to Brake Pressure Modulator Valve Assembly Replacement .
9. Perform the Diagnostic System Check - ABS
