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 battery negative cable.
2. Remove the EBCM wiring harness connectors.
3. Remove the bolts (1) 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.

4. Remove the EBCM (2) from the BPMV (4). Removal may require a light amount of force.
5. Clean the BPMV with a clean, dry cloth.

### Installation Procedure

Important:

• | After installation, calibrate the new EBCM to the tire size that is appropriate to the vehicle. Refer to ABS Description and Operation .

• | If the EBCM mounting bolts are corroded or damaged, do not reuse the old mounting bolts. Install new EBCM mounting bolts with the new EBCM.

• | Do not use RTV or any other type of sealant on the EBCM to BPMV mating surface.

1. Install the EBCM (2) to the BPMV (4).

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 4 EBCM bolts (1).

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

3. Connect the 4 electrical connectors to the EBCM.
4. Connect the negative battery cable.
5. Revise the tire calibration using the Scan Tool .
6. Return to Diagnostic System Check. Refer to Diagnostic System Check - ABS .
