  4. 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 are OK, go to step 5.
  5. Reconnect the connector to the keyless receiver 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, go to step 6
