DETECTION CONDITION
•  Open circuit in door lock-link switch (driver-side) unlock signal circuit with front door (driver-side) closed.
POSSIBLE CAUSE
•  Front door latch and lock actuator (driver-side) connector or terminals malfunction
•  Open circuit in wiring harness between front door latch and lock actuator (driver-side) terminal D and body ground
•  Door lock-link switch (driver-side) malfunction
•  Theft-deterrent control module connector or terminals malfunction
•  Open circuit in wiring harness between front door latch and lock actuator (driver-side) terminal L and theft-deterrent control module terminal V
•  Theft-deterrent control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER-SIDE) CONNECTOR AND TERMINALS
•  Turn the ignition switch to the LOCK position.
•  Disconnect the negative battery cable.
•  Disconnect the front door latch and lock actuator (driver-side) connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
2
INSPECT DOOR LOCK-LINK SWITCH (DRIVER-SIDE) GROUND CIRCUIT FOR OPEN CIRCUIT
•  Verify that the front door latch and lock actuator (driver-side) connector is disconnected.
•  Inspect for continuity between front door latch and lock actuator (driver-side) terminal D (wiring harness-side) and body ground:
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
3
INSPECT DOOR LOCK-LINK SWITCH (DRIVER-SIDE)
•  Inspect the door lock-link switch (driver-side).
•  Is there any malfunction?
Yes
Replace the front door latch and lock actuator (driver-side), then go to Step 6.
(See FRONT DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
No
Go to the next step.
4
INSPECT THEFT-DETERRENT CONTROL MODULE CONNECTOR AND TERMINALS
•  Disconnect the theft-deterrent control module connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
5
INSPECT DOOR LOCK-LINK SWITCH (DRIVER-SIDE) CIRCUIT FOR OPEN CIRCUIT
•  Verify that the front door latch and lock actuator (driver-side) and theft-deterrent control module connectors are disconnected.
•  Inspect for continuity between front door latch and lock actuator (driver-side) terminal L (wiring harness-side) and theft-deterrent control module terminal V (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
6
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC using the M-MDS.
•  Perform the theft-deterrent control module DTC inspection using the M-MDS with the front door (driver-side) closed.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the theft-deterrent control module.
Go to the next step.
No
Go to the next step.
7
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [THEFT-DETERRENT SYSTEM].)
No
DTC troubleshooting completed.
