    Object Number: 1961209  Size: SH
  1. Turn the ignition switch to the OFF position.
  2. Clean the electronic brake control module (EBCM) to brake pressure modulator valve (BPMV) area of any accumulated dirt and foreign material.
  3. Disconnect the electrical connector from the EBCM.
  4. Remove the 4 EBCM bolts (1).

  5. Object Number: 1961213  Size: SH
  6. Separate the EBCM (1) from the BPMV by carefully pulling the components apart.

Installation Procedure
