Removal Procedure
Warning: Refer to Brake Fluid Irritant Warning (Brake Fluid Irritant Warning).


Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution (Brake Fluid Effects on Paint and Electrical Components Caution).

1. Turn the ignition switch to the OFF position.
2. Disconnect the electronic brake control module (EBCM) electrical connector.




3. Clean the area around the brake pipe fittings and the EBCM and the brake pressure modulator valve (BPMV) mating surfaces of any accumulated dirt and debris.
4. Disconnect the RF brake pipe fitting (1) from the EBCM/BPMV assembly.
Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.




5. Disconnect the RR brake pipe fitting (1) from the EBCM/BPMV assembly.
Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.




6. Disconnect the LR brake pipe fitting (1) from the EBCM/BPMV assembly.
Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.




7. Disconnect the LF brake pipe fitting (1) from the EBCM/BPMV assembly.
Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.




8. Disconnect the master cylinder primary brake pipe fitting (1) from the EBCM/BPMV assembly.
Cap the brake pipe fitting and plug the BPMV inlet port to prevent brake fluid loss and contamination.




9. Disconnect the master cylinder secondary brake pipe fitting (1) from the EBCM/BPMV assembly.
Cap the brake pipe fitting and plug the BPMV inlet port to prevent brake fluid loss and contamination.




10. Remove the EBCM/BPMV assembly bracket nuts (1).




11. Remove the EBCM/BPMV assembly (1).




12. If necessary, remove the BPMV bracket bolts (1).




13. If necessary, remove the bracket (1) from the BPMV.
14. Remove the EBCM. Refer to Electronic Brake Control Module Replacement (Service and Repair).

Installation Procedure

1. Install the EBCM. Refer to Electronic Brake Control Module Replacement (Service and Repair).




2. If removed, install the bracket (1) to the BPMV.

Caution: Refer to Fastener Caution (Fastener Caution).




3. If removed, install the BPMV bracket bolts (1) and tighten to 11 Nm (97 lb in).




4. Install the EBCM/BPMV assembly (1) to the vehicle.




5. Install the EBCM/BPMV assembly bracket nuts (1) and tighten to 9 Nm (80 lb in).



Connect the master cylinder secondary brake pipe fitting (1) to the EBCM/BPMV assembly and tighten to 32 Nm (24 lb ft).



Connect the master cylinder primary brake pipe fitting (1) to the EBCM/BPMV assembly and tighten to 32 Nm (24 lb ft).



Connect the LF brake pipe fitting (1) to the EBCM/BPMV assembly and tighten to 17 Nm (13 lb ft).



Connect the LR brake pipe fitting (1) to the EBCM/BPMV assembly and tighten to 17 Nm (13 lb ft).




6. Connect the RR brake pipe fitting (1) to the EBCM/BPMV assembly and tighten to 17 Nm (13 lb ft).




7. Connect the RF brake pipe fitting (1) to the EBCM/BPMV assembly and tighten to 17 Nm (13 lb ft).
8. Connect the EBCM electrical connector.
9. Perform the Antilock Brake System Automated Bleed Procedure (Service and Repair).
