1. Disconnect the negative battery cable.
2. Raise and suitably support the vehicle.

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

3. Thoroughly was all contaminants from around the EHCU (1).

4. Disconnect the electrical connectors from the EBCM.
5. Loosen or remove the bolts (4) securing the EHCU mounting bracket (3) to the frame rail (5).
6. Gently move the EHCU down enough to remove the 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.
   NOTE: Do not use a tool to pry the EBCM or the BPMV. Excessive force will damage the EBCM.
8. Clean the BPMV to EBCM mounting surfaces with a clean cloth.
