Brake Pressure Modulator Valve Replacement HP7

Warning: Refer to Brake Fluid Irritant Warning in the Preface section.

Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution in the Preface section.

Caution: Always connect or disconnect the wiring harness connector from the EBCM/EBTCM with the ignition switch in the OFF position. Failure to observe this precaution could result in damage to the EBCM/EBTCM.

1. Turn the ignition switch to the OFF position.
2. Remove the battery. Refer to Battery Replacement.
3. Without draining the coolant or removing the hoses, remove and position aside the radiator surge tank. Refer to Radiator Surge Tank Replacement.



4. Disconnect the electronic brake control module (EBCM) electrical connector by lifting the locking tabs.
5. Disconnect the LF brake pipe fitting (1) at the brake pressure modulator valve (BPMV).

Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.

6. Disconnect the RF brake pipe fitting (2) from the BPMV.

Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.




7. Disconnect the master cylinder primary brake pipe fitting (1) from the BPMV.

Cap the brake pipe fitting and plug the BPMV inlet port to prevent brake fluid loss and contamination.

8. Disconnect the master cylinder secondary brake pipe fitting (2) from the BPMV.

Cap the brake pipe fitting and plug the BPMV inlet port to prevent brake fluid loss and contamination.




9. Disconnect the LR brake pipe fitting (1) from the BPMV.

Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.

10. Disconnect the RR brake pipe fitting (2) from the BPMV.

Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.

11. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.



12. Remove the BPMV bracket bolts (1).
13. Position the BPMV and bracket assembly to access the BPMV bolt.



14. Remove the BPMV bolt (1).



15. Carefully remove the BPMV assembly (1) by pulling straight upward.

Do not pry on the accumulator caps on the underside of the BPMV.

16. Inspect the insulators for damage and replace, if necessary.

1. Install the BPMV assembly (1) to the bracket.

Caution: Refer to Fastener Caution in the Preface section.




2. Install the BPMV bolt (1) and tighten to 10 N·m (89 lb in).



3. Install the BPMV bracket bolts (1) and tighten to 10 N·m (89 lb in).
4. Lower the vehicle.



5. Connect the LR brake pipe fitting (1) to the BPMV and tighten to 21 N·m (16 lb ft).
6. Connect the RR brake pipe fitting (2) to the BPMV and tighten to 21 N·m (16 lb ft).



7. Connect the master cylinder primary brake pipe fitting (1) to the BPMV and tighten to  21 N·m (16 lb ft).
8. Connect the master cylinder secondary brake pipe fitting (2) to the BPMV and tighten to 21 N·m (16 lb ft).



9. Connect the LF brake pipe fitting (1) to the BPMV and tighten to 21 N·m (16 lb ft).
10. Connect the RF brake pipe fitting (2) to the BPMV and tighten to 21 N·m (16 lb ft).
11. Connect the EBCM electrical connector.
12. Install the radiator surge tank. Refer to Radiator Surge Tank Replacement.
13. Install the battery. Refer to Battery Replacement.
14. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding.
15. Turn the ignition switch to the ON position.
16. Perform the Diagnostic System Check - Vehicle.
17. Observe the brake pedal feel after performing the diagnostic system check. If the pedal now feels spongy, air may have been in, or may have been introduced into the primary circuit.

If the pedal feels spongy, perform the Antilock Brake System Automated Bleed Procedure.
