Brake Pressure Modulator Valve Replacement



Brake Pressure Modulator Valve Replacement (With RPO LAT) (2.4L)
Caution: Refer to Brake Fluid Irritant Caution .

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice .


Notice: Always connect or disconnect the wiring harness connector from the EBCM/EBTCM with the ignition switch in the OFF position. Failure to observe this precaution could result in damage to the EBCM/EBTCM.



Removal Procedure





1. Turn the ignition switch to the OFF position.
2. Clean the brake pressure modulator valve (BPMV) pipe fitting areas of any accumulated dirt and foreign material.
3. Disconnect the electrical connector from the electronic brake control module (EBCM).
4. Place a shop towel under the BPMV to catch any brake fluid loss.
5. Disconnect the brake pressure sensor electrical connector.

Important: Note the location of the brake pipes to aid installation.






6. Disconnect the master cylinder brake pipe fittings (1).
Cap the brake pipe fittings and plug the BPMV inlet ports to prevent brake fluid loss and contamination.
7. Disconnect the BPMV outlet brake pipe fittings (2).
Cap the brake pipe fittings and plug the BPMV outlet ports to prevent brake fluid loss and contamination.




8. Remove the 4 BPMV bolts.
9. Remove the BPMV from the bracket.
10. If installing a new BPMV, remove the EBCM. Refer to Electronic Brake Control Module Replacement (Without RPO LAT) Electronic Brake Control Module Replacement (With RPO LAT) (Service and Repair) .



Installation Procedure

Important: When installing a new BPMV, do NOT remove the shipping plugs from the pipe ports until after installation into the vehicle.



1. Install the EBCM, if removed. Refer to Electronic Brake Control Module Replacement (Without RPO LAT) Electronic Brake Control Module Replacement (With RPO LAT) (Service and Repair) .




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

Notice: Refer to Fastener Notice .

3. Install the BPMV bolts.

Tighten the bolts to 10 N.m (89 lb in).


Important: Note the location of the brake pipes to aid installation.






4. Connect the master cylinder brake pipe fittings (1).

Tighten the fittings to 20 N.m (15 lb ft).

5. Connect the BPMV outlet brake pipe fittings (2).

Tighten the fittings to 20 N.m (15 lb ft).






Important: Ensure the electrical connector is correctly inserted into the EBCM prior to placing the locking lever into position. Failure to make a proper connection may cause communication problems with the module.


6. Connect the EBCM electrical connector.
7. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding (Manual) (Service and Repair)Hydraulic Brake System Bleeding (Pressure) (Service and Repair) .

Important: Place the ignition switch in the ON position. Do not start the engine.


8. Perform the Diagnostic System Check - Vehicle .
9. Observe the feel of the brake pedal after performing the diagnostic system check. If the pedal now feels spongy, air may have been in the secondary circuit of the brake modulator assembly, which may have been introduced into the primary circuit. If the pedal feels spongy, perform the Antilock Brake System Automated Bleed Procedure (Non-Hybrid Vehicles) (Service and Repair)Antilock Brake System Automated Bleed Procedure (Hybrid Vehicles) (Service and Repair) .
