Important: After installation, calibrate the new EBCM to the tire size that is appropriate to the vehicle. Refer to Tire Size Calibration portion of ABS Description .

1. Negative Battery Cable.




Important: Thoroughly wash all contaminants from around the EHCU (1). The area around the EHCU MUST be free from loose dirt to prevent contamination of disassembled ABS components.

2. Disconnect the electrical connectors from the EBCM.
3. Loosen or Remove 3 bolts (4) securing the EHCU mounting bracket (3) to the frame rail (5).



4. Gently move the EHCU down enough to remove the four T 25 Torx® mounting screws that fasten the EBCM (2) to the BPMV (1).
5. Remove the EBCM (2) from the BPMV (1). Removal may require a light amount of force.

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

6. Clean the BPMV to EBCM mounting surfaces with a clean cloth.

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

Important: Do not use RTV or any other type of sealant on the EBCM gasket or mating surfaces.

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

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 four new T-25 Torx® screws in the EBCM (2).

Tighten
Tighten the four T-25 Torx® screws to 5 N·m (39 lb. in.) in an X-pattern.




3. Install or tighten three EHCU bracket mounting bolts

Tighten
Tighten the EHCU bracket mounting bolts to 25 N·m (18 lb in).

4. Connect the electrical connectors to the EBCM.
5. Connect negative battery cable.
6. Revise the tire calibration using the Scan Tool Tire Size Calibration function. Refer to Scan Tool Diagnostics .
7. Return to Diagnostic System Check - ABS .
