Brake Pressure Modulator Valve (BPMV) Replacement
Brake Pressure Modulator Valve (BPMV) ReplacementRemoval Procedure
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.
2. Disengage the Connector Position Assurance (CPA) (2) from the connector.
3. Push the lock tab (1) down and then move the sliding connector cover to the open position.
4. Disconnect the Electronic Brake Control Module (EBCM) harness connector (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.
Important: Note the locations of the brake pipes in order to aid in installation.
5. Disconnect the wheel cylinder brake pipes from the Brake Pressure Modulator Valve (BPMV) (1).
6. Gently reposition the brake pipes out of the way only after covering the open pipes to avoid dripping or being contaminated.
7. Remove the upper BPMV bracket mounting bolt that connects the upper BPMV mounting bracket (2) to the lower mounting bracket (3).
8. Remove the BPMV (4) and the EBCM (1) as an assembly from the vehicle.
Notice: Be careful not to damage the EBCM seal when removing the EBCM.
9. Remove the EBCM (2) if replacing the BPMV (4) only.
Installation Procedure
1. Install the EBCM (2) onto the BPMV (4) if replacing the BPMV only.
2. Install the BPMV (4) and the EBCM (1) as an assembly to the lower mounting bracket (3).
Notice: Refer to Fastener Notice in Service Precautions.
3. Install the bolt that connects the EBCM/BPMV assembly to the lower mounting bracket (3).
Tighten the bolt that connects the BPMV (4) to the lower mounting bracket (3) to 10 Nm (7 ft. lbs.).
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 during the next few steps when ready.
4. Install the master cylinder brake pipes to the BPMV (1).
Tighten the master cylinder brake pipe fittings to 24 Nm (18 ft. lbs.).
5. Install the wheel cylinder brake pipes to the BPMV (1).
Tighten the wheel cylinder brake pipe fittings to 24 Nm (18 ft. lbs.).
6. Connect the EBCM harness connector (2).
7. Push down the lock tab (1) and then move the sliding connector cover back in the home position to lock.
8. Insert the CPA (2) back into place.
9. When all procedures have been completed, the automated ABS bleed procedure is required.
