POSSIBLE CAUSE
•  Trunk lid latch switch connector or terminals malfunction
•  BCM connector or terminals malfunction
•  Trunk lid latch switch malfunction
•  Short to ground in wiring harness between the following terminals:
―  Trunk lid latch switch terminal C—BCM terminal 6F
•  BCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
CONFIRM BCM DTC
•  Clear the DTC using the M-MDS.
•  Perform the BCM DTC inspection using the M-MDS with the trunk closed (trunk lid latch switch off).
•  Is the same DTC present?
Yes
Go to the next step.
No
Go to Step 7.
2
INSPECT TRUNK LID LATCH SWITCH CONNECTOR AND TERMINALS
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the trunk lid latch 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 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 TRUNK LID LATCH SWITCH CIRCUIT FOR SHORT TO GROUND
•  Trunk lid latch switch and BCM connectors are disconnected.
•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:
―  Trunk lid latch switch terminal C
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 6.
No
Go to the next step.
5
INSPECT TRUNK LID LATCH SWITCH
•  Inspect the trunk lid latch switch.
•  Is there any malfunction?
Yes
Replace the trunk lid latch switch, then go to the next step.
(See TRUNK LID LATCH AND RELEASE ACTUATOR REMOVAL/INSTALLATION.)
No
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 BCM DTC inspection using the M-MDS with the trunk closed (trunk lid latch switch off).
•  Is the same DTC present?
Yes
Replace the BCM, then go to the next step.
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [L.H.D.].)
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [R.H.D.].)
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.
