Brake Pressure Modulator Valve Replacement BPMV Replacement

Notice: To prevent equipment damage, never connect or disconnect the wiring harness connection from the EBCM with the ignition switch in the ON position.

1. Turn the ignition switch to the OFF position.
2. Disconnect the EBTCM harness connector.
3. Remove the brake pipes from the BPMV, noting the location.
4. Remove the BPMV pump motor ground wire.



5. Remove the three insulator nuts (2,3).
6. Remove the EBTCM/BPMV from the vehicle as one unit.



7. Remove the insulator mounting bolt from the EBTCM.
8. Remove the four EBTCM to BPMV bolts.
9. Separate the EBTCM from the BPMV by gently pulling apart until separated. Be careful not to damage seal.

1. Clean the BPMV gasket surface with alcohol using a clean rag.
2. Install the EBTCM to the BPMV.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Tighten
Tighten the four mounting bolts to 3 N·m (27 lb in), then tighten to 6 N·m (53 lb in).

3. Install the front EBTCM insulator mounting bolt.

Tighten
Tighten the EBTCM insulator mounting bolt to 14 N·m (10 lb ft).




4. Install the EBTCM/BPMV into the bracket on the vehicle.
5. Install the three insulator nuts (2,3).

Important: If the insulator nut was removed it must be replaced with a new insulator nut (3).

Tighten
Tighten the three insulator nuts to 10 N·m (89 lb in).





Caution: Make sure brake pipes are correctly connected to BPMV. If brake pipes are switched by mistake Inlet vs. Outlet, wheel lockup will occur and personal injury may result.

Important: If a new BPMV is being installed, remove the shipping plugs from the valve openings in the compartment during the next step.

6. Install the brake pipe from the LR brake (3) on the BPMV.

Tighten
Tighten the brake pipe fitting to 16 N·m (12 lb ft).

7. Install the brake pipe from the RR brake (2) on the BPMV.

Tighten
Tighten the brake pipe fitting to 16 N·m (12 lb ft).

8. Install the brake pipe from the Proportioning Valve (1) on the BPMV.

Tighten
Tighten the brake pipe fitting to 16 N·m (12 lb ft).

9. Install the brake pipe from the LF brake (6) on the BPMV.

Tighten
Tighten the brake pipe fitting to 16 N·m (12 lb ft).

10. Install the brake pipe from the RF brake (5) on the BPMV.

Tighten
Tighten the brake pipe fitting to 16 N·m (12 lb ft).

11. Install the brake pipe from the Master Cylinder or the Combination Valve if the vehicle is equipped with Active Handling (4) on the BPMV.

Tighten
Tighten the brake pipe fitting to 16 N·m (12 lb ft).

12. Connect the BPMV pump motor ground.
13. Connect the EBTCM harness connector.

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

14. Turn the ignition switch to the ON position, engine off.
15. Perform the Diagnostic System Check - ABS .
