Electronic Brake Control Module (EBCM) Replacement
Removal Procedure
Important: After installation, calibrate the new 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 two 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 four T 25 Torx(R) mounting screws (1) that fasten the EBCM (2) to the BPMP (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.
Installation Procedure
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: Refer to Fastener Notice in Service Precautions.
2. Install the four new T-25 Torx(R) screws (1) in the EBCM (2).
^ Tighten the four T-25 Torx(R) screws to 5 Nm (39 inch lbs.) 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 two nuts (4).
5. Revise the tire calibration using the Scan Tool Tire Size Calibration function.
6. Return to Diagnostic System Check - ABS.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
