Power Door Lock Control Module: Testing and Inspection

Power Door Locks

Control Unit Input Test

1. Remove the driver's pocket.




2. Disconnect the 18P connector (B) from the keyless door lock control unit (A).
3. Inspect the connector and socket terminals to be sure they are 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 4.







4. With the connector still disconnected, 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 5.




5. Reconnect the 18P connector to the keyless door lock 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 control unit must be faulty; replace the keyless door lock control unit.
