Fig. 85 EBCM & APV Valve Assembly Replacement.

    When replacing the EBCM be sure to use the correct replacement EBCM for the system that is being serviced. The 3500 HD uses the
ZPRWAL EBCM with the gray electrical connector. All other models use the RWAL EBCM with the black electrical connector. Failure to use
the correct EBCM will result in system malfunction.
