Measure the resistance between the DDM C501 a-7, circuit 91-AJ80 (BN/BU), harness side and ground and between the DDM C501a-8, circuit 31-AJ80B (BK/OG), harness side and ground. Is the resistance less than 10 ohms? Yes : Go To «PINPOINT TEST J: THE DRIVER DOOR MODULE (DDM) DOES NOT RESPOND TO THE DIAGNOSTIC TOOL»(ref-207567-S11693730992005113000000) . No : REPAIR the circuit in question. TEST the system for normal operation.
