Removal Procedure

Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.

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

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. Remove the battery.
2. Remove the battery tray.

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

Disconnect the caliper and wheel cylinder brake pipes (2) from the Brake Pedal Modulator Valve (BPMV) (3). Cover the ends of the brake pipes to avoid dripping or contamination.
4. Disconnect the master cylinder brake pipes (1) from the BPMV (3). Cover the ends of the brake pipes to avoid dripping or contamination.
5. Raise and support the vehicle on a suitable hoist.
6. Remove the front engine splash shield.
7. Remove the left engine splash shield.





8. Disconnect the Connector Position Assurance (CPA) (2) from the Electronic Brake Control Module (EBCM) connector.
