For 1990-2009 cars

### 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.

1. Turn the ignition switch to the OFF position.
2. Disconnect the EBCM/EBTCM harness connector (6).

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

3. Disconnect the brake pipes from the BPMV.
4. Remove the two nuts that connect the BPMV to the BPMV bracket (3).

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.

5. Remove the BPMV and EBCM/EBTCM as an assembly from the vehicle (5).

### Installation Procedure

1. Install BPMV and EBCM/EBTCM as an assembly into the BPMV bracket (2).
2. Install the two BPMV bracket nuts (3).

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.

3. Install the brake pipes on to the BPMV.

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

4. Connect the EBCM/EBTCM harness connector (6).
5. Turn the ignition switch to the RUN position, engine off.
6. Perform the Diagnostic System Check
