Diagnostic Procedure

Step

Inspection

Action

1

VERIFY BCM DTCs

•  Clear the DTCs using the M-MDS.
(See CLEARING DTC [BCM].)

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the same DTC present?

Yes

Go to the next step.

No

Go to Step 8.

2

INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (PASSENGER-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 (passenger-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 7.

No

Go to the next step.

3

INSPECT FRONT DOOR LATCH SWITCH (PASSENGER-SIDE) GROUND CIRCUIT FOR OPEN CIRCUIT

•  Verify that the front door latch and lock actuator (passenger-side) connector is disconnected.

•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:

―  L.H.D.

•  Front door latch and lock actuator (passenger-side) terminal D

―  R.H.D.

•  Front door latch and lock actuator (passenger-side) terminal J

•  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 7.

4

INSPECT FRONT DOOR LATCH SWITCH (PASSENGER-SIDE)

•  Inspect the front door latch switch (passenger-side).
(See FRONT DOOR LATCH SWITCH INSPECTION.)

•  Is there any malfunction?

Yes

Replace the front door latch and lock actuator (passenger-side), then go to Step 7.

(See FRONT DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)

No

Go to the next step.

5

INSPECT BCM CONNECTOR AND TERMINALS

•  Disconnect the BCM 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 7.

No

Go to the next step.

6

INSPECT FRONT DOOR LATCH SWITCH (PASSENGER-SIDE) CIRCUIT FOR OPEN CIRCUIT

•  Verify that the front door latch and lock actuator (passenger-side) and BCM connectors are disconnected.

•  Inspect for continuity between the following terminals (wiring harness-side):

―  L.H.D.

•  Front door latch and lock actuator (passenger-side) terminal B and BCM terminal 7M

―  R.H.D.

•  Front door latch and lock actuator (passenger-side) terminal L and BCM terminal 7M

•  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.

7

VERIFY TROUBLESHOOTING COMPLETED

•  Make sure to reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

•  Clear the DTCs using the M-MDS.
(See CLEARING DTC [BCM].)

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the same DTC present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the BCM.
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)

Go to the next step.

No

Go to the next step.

8

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [BCM].)

No

DTC troubleshooting completed.
