    NOTE: The area around the EHCU MUST be free from loose dirt to prevent contamination of disassembled ABS components.

  4. Disconnect the electrical connectors from the EBCM.
  5. Loosen or remove 3 bolts (4) securing the EHCU mounting bracket (3) to the frame rail (5).
  6. Gently move the EHCU down enough to remove the four mounting screws that fasten the EBCM (2) to the BPMV (1).
  7. Remove the EBCM (2) from the BPMV (1). Removal may require a light amount of force.
  8. Clean the BPMV to EBCM mounting surfaces with a clean cloth.
