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 7.

2

INSPECT INTERIOR LIGHT CONNECTOR AND TERMINALS

•  Turn the ignition switch to the LOCK position.

•  Disconnect the negative battery cable.

•  Disconnect the interior light 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.

3

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 6.

No

Go to the next step.

4

INSPECT INTERIOR LIGHT CIRCUIT FOR SHORT TO POWER SUPPLY

•  Verify that the interior light and BCM connectors are disconnected.

•  Reconnect the negative battery cable.

•  Turn the ignition switch to the ON position.

•  Measure the voltage at the following terminal (wiring harness-side):

―  Vehicles with theft-deterrent system

•  Interior light terminal F

―  Vehicles without theft-deterrent system

•  Interior light terminal C

•  Is there any voltage?

Yes

Repair or replace the wiring harness for a possible short to power supply, then go to Step 6.

No

Go to the next step.

5

INSPECT INTERIOR LIGHT

•  Inspect the interior light.
(See INTERIOR LIGHT INSPECTION.)

•  Is there any malfunction?

Yes

Replace the interior light, then go to the next step.

(See INTERIOR LIGHT REMOVAL/INSTALLATION.)

No

Go to the next step.

6

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.

7

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.
