Important: After installation, calibrate the new electronic brake control module (EBCM) to the tire size that is appropriate to the vehicle.

1. Remove the fuel pipe shield (3) from the frame bracket (2) by removing the 2 nuts (4).

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. Remove the mounting screws (1) that fasten the EBCM (2) to the brake pressure modulator valve (BPMV) (5).
4. Remove the EBCM (2) from the BPMV (5). 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.

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

Important: Do not reuse the old mounting screws (1). 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 (5).

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 new screws (1) in the EBCM (2).

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




3. Connect the electrical connectors to the EBCM.
4. Secure the module (1) to the frame bracket (3) and fuel pipe shield (2) with the 2 nuts (4).
5. Revise the tire calibration using the Scan Tool Tire Size Calibration function.
6. Return to Diagnostic Starting Point - Antilock Brake System .
7. Refer to Control Module References for programming and setup information.
