Brake Pressure Modulator Valve (BPMV) Replacement

Removal Procedure





1. Turn the ignition switch to the OFF position.
2. Disconnect the electronic brake control module (EBCM) harness connector.
3. Remove the brake pressure modulator valve (BPMV) pump motor ground wire.
4. Remove the brake pipes from the master cylinder to the BPMV (1, 2), noting the location.





5. Remove the brake pipes from the BPMV (1, 2) to the front brake calipers, noting the location.





6. Remove the brake pipes from the BPMV (1, 2) to the rear brake calipers, noting the location.





7. Disconnect the electrical connector from the brake fluid pressure sensor (2).
8. Remove the two insulator nuts (1).
9. Remove the EBCM/BPMV from the vehicle as one unit.





10. Remove the insulator mounting bolt from the EBCM.
11. Remove the four EBCM to BPMV bolts.
12. Separate the EBCM from the BPMV by gently pulling apart until separated.
13. Carefully remove the seal. The seal may be reused if it is not cut or damaged.

Installation Procedure





1. Important: When installing a new BPMV, do NOT remove the shipping plugs from the outlets until after installation into the vehicle.

Clean the BPMV seal surface with alcohol using a clean rag.
2. Install the seal to the BPMV, if it is not cut or damaged.
3. Install the EBCM to the BPMV.

4. Notice: Refer to Fastener Notice in Service Precautions.

Install the mounting bolts in the following sequence:
^ First pass to 3 Nm (27 inch lbs.).
^ Second pass to 6 Nm (53 inch lbs.).

5. Install the EBCM/BPMV insulator mounting bolt.
Tighten the bolt to 14 Nm (10 ft. lbs.).





6. Install the EBCM/BPMV into the bracket on the vehicle.
7. Install the two insulator nuts (1).
Tighten the to 12 Nm (106 inch lbs.).
8. Connect the brake fluid pressure sensor electrical connector (2).





9. Install the brake pipes from the rear brake calipers (1, 2) to the BPMV in the same location as removed.
Tighten the brake pipe fittings to 16 Nm (12 ft. lbs.).





10. Install the brake pipes from the front brake calipers (1, 2) to the BPMV in the same location as removed.
Tighten the brake pipe fittings to 16 Nm (12 ft. lbs.).





11. Install the brake pipes from the master cylinder (1, 2) to the BPMV in the same location as removed.
Tighten the brake pipe fittings to 16 Nm (12 ft. lbs.).
12. Connect the BPMV pump motor ground.
13. Connect the EBCM harness connector.

Important: Both sides of the EBCM harness connector must be engaged with lever before closing.

14. Turn the ignition switch to the ON position; do NOT start the engine.
15. Fill and bleed the hydraulic brake system.
16. Perform the Automated Bleed Procedure.
17. Perform the Symptoms - Antilock Brake System.
