Removal Procedure
Important: After installation, calibrate the new EBCM to the tire size that is appropriate to the vehicle.
1. Raise and suitably support the vehicle. Refer to Vehicle Lifting.
2. Remove the EHCU (1) shield bolts and shield.
3. Disconnect the electrical connectors from EBCM.
4. Remove the bolts (1) that fasten the EHCU bracket to the frame.
Important: Be careful not to bend the brake pipes attached to the EHCU.
5. Remove the EHCU from the frame allowing enough clearance to access the EBCM.
6. Remove the T-25 Torx(R) bolts (1) that fasten the EBCM to the BPMV.
Remove the EBCM(2) from the BPMV(4). Removal may require a light amount of force.
Important: Do not use a tool to pry the EBCM or the BPMV.
7. Clean the BPMV with a clean, dry cloth.
Installation Procedure
Important:
^ 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 gasket or mating surfaces.
1. Install EBCM(2) to BPMV(4).
Notice: Refer to Fastener Notice in Service Precautions.
2. Install the EBCM bolts (1).
Tighten the bolts to 5 Nm (39 inch lbs.) in an X-pattern.
3. Connect the electrical connectors to the EBCM.
4. Install the EHCU Shield.
Tighten the bolts to 12 Nm (8 ft. lbs.).
5. Lower the vehicle.
6. Revise the tire calibration using the Scan Tool.
7. Return to Diagnostic System Check. Refer to Diagnostic System Check - ABS.
