2. Disconnect the electronic brake control module (EBCM) harness connector.
3. Remove the 2 insulator nuts (1).
4. Lift the EBCM/brake pressure modulated valve (BPMV) out of the bracket high enough to allow clearance to remove the insulator mounting bolt and the EBCM.





5. Remove the insulator mounting bolt from the EBCM.
6. Remove the 6 EBCM to BPMV bolts.
7. Separate the EBCM from the BPMV by gently pulling apart until separated.
