- If all the input tests prove OK, go to step 4.




4. Reconnect the connector to the control unit, and perform the following input tests at the keyless door lock control unit connector.
- If any test indicates a problem, find and correct the cause then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace it.
