For 1990-2009 cars

### Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Remove the 3 EBCM electrical connectors.
3. Remove the combination valve electrical connector.
4. Remove the 5 brake lines from the BPMV.
5. Remove the BPMV pump motor electrical connector from the EBCM.
6. Remove the 4 T-25 TORX® bolts that fasten the EBCM to the BPMV.

Notice: Do not use a tool to pry the EBCM from the BPMV. Excessive force will damage the EBCM.

7. Remove the EBCM from the BPMV (2). Removal may require a light amount of force.
8. Remove the 3 BPMV mounting bracket nuts (3) and washers (4).
9. Remove the BPMV (4) from the EHCU mounting bracket (2).
10. Clean the BPMV (1) with a clean, dry cloth.

### Installation Procedure

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.

Important: Do not reuse the EBCM mounting bolts. Always install new EBCM mounting bolts with the new EBCM.

1. Install the BPMV (4) onto the EHCU (7) mounting bracket.

Tighten
Tighten the 3 bolts (9) to 9 N·m (7 lb ft).

2. Install the three tube adapters (6).

Tighten
Tighten the tube adapters to 31 N·m (23 lb ft).

3. Install the combination valve onto the BPMV (4).
4. Install the 3 combination valve fastening bolts.

Tighten
Tighten the three bolts first to 8 N·m (6 lb ft) and then to 16 N·m (12 lb ft).

5. Install EBCM (2) to BPMV (4).
6. Install the 4 new EBCM bolts (1).

Tighten
Tighten the 4 bolts to 5 N·m (39 lb in) in an X-pattern.

7. Install the BPMV pump motor electrical connector to the EBCM.
8. Install the EHCU to vehicle.
9. Connect the 3 electrical connectors to the EBCM.
10. Connect the 5 brake lines to the combination valve.

Tighten
Tighten the 5 brake lines to 30 N·m (22 lb ft).

11. Connect the negative battery cable.
12. Bleed the brake system. Refer to Antilock Brake System Automated Bleed Procedure .
13. Return to Diagnostic System Check. Refer to Diagnostic System Check - ABS .
