13. Disconnect the right front brake pipe fitting (1).
Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid leaks and contamination.
Do not force the components apart.
14. Disconnect the left front brake pipe fitting (2).
Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid leaks and contamination.




15. Disconnect the master cylinder secondary brake pipe fitting (1).
Cap the brake pipe fitting and plug the BPMV inlet port to prevent brake fluid leaks and contamination.
16. Disconnect the master cylinder primary brake pipe fitting (2).
Cap the brake pipe fitting and plug the BPMV inlet port to prevent brake fluid leaks and contamination.




17. Remove the BPMV nuts (1).




18. Remove the EBCM/BPMV module assembly (1) from the bracket.




19. Remove the BPMV insulators (1).
Inspect the insulators for damage and replace, if necessary.




20. Remove the EBCM bolts (1).

Note: Do not attempt to pry or lever the EBCM from the BPMV.




21. Carefully remove the EBCM (1) from the BPMV.
Do not force the components apart.
22. Clean the mating surfaces of the EBCM and the BPMV with denatured alcohol and allow to dry.

Installation Procedure




1. Carefully install the EBCM (1) to the BPMV.
