Removal Procedure
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.
- Turn the ignition switch
to the OFF position.
- Pull out lock tab (1) from EBTCM harness connector.
- Disconnect the EBTCM harness connector.
Important: Note the locations of the brake pipes in order to aid in installation.
- Disconnect the wheel cylinder brake pipes (1) from the BPMV (2).
- Disconnect the master
cylinder brake pipes (1) from the BPMV (2).
- Remove the two 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.
- Remove the BPMV (2) and EBTCM as an assembly from the vehicle.
- Remove EBTCM if replacing the BPMV only. Refer to
Electronic Brake and Traction Control Module Replacement
.
Installation Procedure
- Install EBTCM if replacing
the BPMV only. Refer to
Electronic Brake and Traction Control Module Replacement
.
- Install BPMV (2) and EBTCM as an assembly into the BPMV bracket.
Align the flats of the studs on the BPMV with the BPMV bracket.
- Install the two BPMV to BPMV bracket nuts (1).
Tighten
Tighten the two BPMV to BPMV bracket nuts to 12 N·m (8
lb. ft.).
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.
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.
- Install the master cylinder brake pipes (1) on the BPMV (2).
- Install the wheel cylinder
brake pipes (1) on the BPMV (2).
Tighten
Tighten all of the brake pipe fittings to 15 N·m (11 lb ft).
- Connect the EBTCM harness
connector. Push in lock tab (1).
- Fill and bleed the brake hydraulic system. Refer to
Hydraulic Brake System Bleeding
in Hydraulic Brakes.
- Turn the ignition switch to the RUN position, engine off.
- Perform the
Diagnostic System Check - ABS
