VERIFY BCM DTCs AGAIN
• Clear the DTC for the BCM using the M-MDS.
• Open/close the trunk.
• Retrieve the BCM DTCs using the M-MDS.
• Is the same Pending DTC present?
|
Yes
|
Go to the next step.

|
No
|
Go to Step 7.

INSPECT TRUNK LID LATCH SWITCH CIRCUIT FOR SHORT TO GROUND
• Verify that the trunk lid latch switch and BCM connectors are disconnected.
• Inspect for continuity between trunk lid latch switch terminal A (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify whether or not there is a common connector between trunk lid latch switch terminal A and BCM terminal 2AC.
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to ground.
Go to the next step.

• Connect the negative battery terminal.
• Clear the DTC for the BCM using the M-MDS.
• Open/close the trunk.
• Retrieve the BCM DTCs using the M-MDS.
• Is the same Pending DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the BCM.
Go to the next step.
