Brake Pressure Modulator Valve Replacement Rear Mounted EBTCM/BPMV

Caution: For safety reasons, the brake pressure modulator valve assembly must not be repaired, the complete unit must be replaced. With the exception of the EBCM, no screws on the brake pressure modulator valve assembly may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.

1. Turn the ignition switch to the OFF position.

Important: Allow the stabilizer shaft to hang down in order to provide clearance.




2. Remove the RH stabilizer shaft insulator clamp.
3. Remove the LH stabilizer shaft insulator clamp.
4. Remove the brake pipes from the BPMV, noting the location.
5. Disconnect the EBTCM harness connector.
6. Remove the BPMV pump motor ground wire.



7. Remove the right side EBTCM/BPMV bracket (2) from the crossmember by removing the three bolts (3).
8. Remove the EBTCM and the BPMV together as one unit.



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

1. Clean the seal and 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

11. Install the brake pipe from the LR brake (2) on the BPMV.

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

12. Install the brake pipe from the RR brake (1) on the BPMV.

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

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

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

15. Move the stabilizer shaft into position.
16. Install the LH stabilizer shaft insulator clamp.

Tighten
Tighten the upper bolt to 65 N·m (49 lb ft).

Tighten the lower bolt to 95 N·m (71 lb ft).

17. Install the RH stabilizer shaft insulator clamp.

Tighten
Tighten the upper bolt to 65 N·m (49 lb ft).

Tighten the lower bolt to 95 N·m (71 lb ft).

18. Turn the ignition switch to the ON position, engine off.
19. Fill the master cylinder reservoir.
20. Bleed the system. Refer to Pressure Bleeding in Hydraulic Brakes if proper brake pedal height and feel do not return after the Pressure Brake System Bleeding perform the Antilock Brake System Automated Bleed Procedure .
21. Perform the Diagnostic System Check .
