Body Electrical System TROUBLE DIAGNOSES OF SYSTEM SYSTEM CHECK ON CAR STEP 1. A harness checker should always be used when anything goes wrong with this system. Do not attempt to disassemble or adjust the interlock unit. Trouble shooting should begin by checking whether or not the conditions alleged by the customer recur. Starting motor will not rotate, therefore engine will not start. Repeat above operations after connecting new interlock unit with connectors. Engine starts properly. The system is in good condition. Starting motor will not rotate, therefore engine will not start. System problem other than interlock unit. Proceed to STEP 2 or 3. Engine starts properly. Interlock unit problem. Replace interlock unit. STEP 2. Inspection with the harness checker. 1. Disconnect interlock unit at connectors. 2. Connect the checker with connectors as shown below. Identify which check light is off and check interlock relay operation. Replace interlock relay if inoperative and replace the parts indicated by each check light which remains off. Fig. BE-149 BE174A Connecting the checker with dash harness connectors BE-91
