Brake Pressure Modulator Valve Replacement

Brake Pressure Modulator Valve Replacement

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

Caution: For safety reasons, the Brake Pressure Modulator Valve (BPMV) must not be repaired; the complete unit must be replaced. With the exception of the EBCM/EBTCM, no screws may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.


Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice (Vehicle Damage Warnings) .






1. Turn the ignition switch to the OFF position.
2. Pull out lock tab (1) from electronic brake control module (EBCM) harness connector.
3. Disconnect the EBCM harness connector.





Important: Note the locations of the brake pipes in order to aid in installation.


4. Disconnect the wheel cylinder brake pipes (1) from the brake pressure modulator valve (BPMV) (2).




5. Disconnect the master cylinder brake pipes (1) from the BPMV (2).




6. Remove the 2 nuts (1) that connect the BPMV to the BPMV bracket.

Notice: When removing the brake pressure modulator valve, protect the vehicle exterior from possible brake fluid spillage. Brake fluid can cause damage to painted surfaces.

7. Remove the BPMV (2) and EBCM as an assembly from the vehicle.
8. Remove EBCM if replacing the BPMV only. Refer to Electronic Brake Control Module Replacement (Service and Repair) .



Installation Procedure





1. Install EBCM if replacing the BPMV only. Refer to Electronic Brake Control Module Replacement (Service and Repair) .
2. Install BPMV (2) and EBCM as an assembly into the BPMV bracket. Align the flats of the studs on the BPMV with the BPMV bracket.

Notice: Refer to Fastener Notice (Fastener Notice) .

3. Install the 2 BPMV to BPMV bracket nuts (1).

Tighten the 2 BPMV to BPMV bracket nuts to 12 N.m (8 lb ft).






Caution: Make sure brake pipes are correctly connected to brake pressure modulator valve. If brake pipes are switched by mistake, wheel lockup will occur and personal injury may result. The only two ways this condition can be detected are by using a Scan Tool or by doing an Antilock stop.


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



Important: Use the locations noted during removal.


4. Install the master cylinder brake pipes (1) on the BPMV (2).




5. Install the wheel cylinder brake pipes (1) on the BPMV (2).

Tighten all of the brake pipe fittings to 15 N.m (11 lb ft).





6. Connect the EBCM harness connector. Push in lock tab (1).
7. Fill and bleed the brake hydraulic system. Refer to Hydraulic Brake System Bleeding (Manual) (Service and Repair)Hydraulic Brake System Bleeding (Pressure) (Service and Repair) .
8. Turn the ignition switch to the RUN position, engine off.
9. Perform the Diagnostic Starting Point - Antilock Brake System (Diagnostic Starting Point - Antilock Brake System) .
