Removal & Installation




CAUTION
For safety reasons, the Brake Pressure Modulator Valve (BPMV) assembly must not be repaired; the complete unit must be replaced. With the exception of the Electronic Brake Control Module (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. Disconnect the negative battery cable.
  2.  
  3. Remove the air cleaner assembly.
  4.  
  5. Reposition the Powertrain Control Module (PCM) to create access to the Brake Pressure Modulator Valve (BPMV).
    NOTE
    Note the location of the brake pipes to use as an aid during instillation.


    WARNING
     When removing the brake pressure modulator valve, protect the vehicle exterior from possible brake fluid spillage. Brake fluid can cause damage to painted surfaces.


    NOTE
    Excessive bending of brake pipes during BPMV removal or installation may cause permanent damage that will require replacement.

  6.  
  7. Remove the 6 brake pipe fittings.
  8.  
  9. Disconnect the Electronic Brake Control Module (EBCM) connector and BPMV motor ground cable.
  10.  
  11. Remove the 3 EBCM/BPMV assembly bracket nuts.
  12.  
  13. Disconnect and reposition the 2 transmission cooler lines.
