Diagnostic Procedure

Step

Inspection

Action

1

INSPECT LIFTGATE OPENER SWITCH CONNECTOR AND TERMINALS

•  Turn the ignition switch to the LOCK position.

•  Disconnect the negative battery cable.

•  Disconnect the liftgate opener switch 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 8.

No

Go to the next step.

2

INSPECT LIFTGATE OPENER SWITCH

•  Inspect the liftgate opener switch.
(See LIFTGATE OPENER SWITCH INSPECTION.)

•  Is there any malfunction?

Yes

Replace the liftgate opener switch, then go to Step 8.

(See LIFTGATE OPENER SWITCH REMOVAL/INSTALLATION.)

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 8.

No

Go to the next step.

4

INSPECT LIFTGATE OPENER SWITCH CIRCUIT FOR SHORT TO GROUND

•  Verify that the liftgate opener switch and BCM connectors are disconnected.

•  Inspect for continuity between liftgate opener switch terminal B (wiring harness-side) and body ground.

•  Is there continuity?

Yes

Repair or replace the wiring harness for a possible short to ground, then go to Step 8.

No

Go to the next step.

5

INSPECT KEYLESS CONTROL MODULE CONNECTOR AND TERMINALS

•  Disconnect the keyless 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 8.

No

Go to the next step.

6

INSPECT LIFTGATE OPENER SWITCH CIRCUIT FOR SHORT TO GROUND

•  Verify that the liftgate opener switch and BCM and keyless control module connectors are disconnected.

•  Inspect for continuity between liftgate opener switch terminal A (wiring harness-side) and body ground.

•  Is there continuity?

Yes

Repair or replace the wiring harness for a possible short to ground, then go to Step 8.

No

Go to the next step.

7

INSPECT BCM

•  Make sure to reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

•  Measure the voltage at the BCM terminal 7A (wiring harness-side).

•  Is the voltage normal?
(See BODY CONTROL MODULE (BCM) INSPECTION.)

Yes

Go to the next step.

No

Replace the BCM, then go to the next step.

(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)

8

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 [ADVANCED KEYLESS AND START SYSTEM].)

•  Perform the keyless control module DTC inspection using the M-MDS.
(See DTC INSPECTION [ADVANCED KEYLESS AND START SYSTEM].)

•  Is the same DTC present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the keyless control module.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS AND START SYSTEM].)

Go to the next step.

No

Go to the next step.

9

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [ADVANCED KEYLESS AND START SYSTEM].)

No
