5. Inspect the connector and socket terminals to be sure they are all making good contact.
• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, go to step 6.
6. Reconnect all the connector to the control unit, and make these input tests at the connector.
• If any test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, the combination switch control unit must be faulty, replace the combination
