Diagnostic Procedure

STEP

INSPECTION

ACTION

1
INSPECT DOOR LATCH FOR GEM PID
Monitor the following GEM PIDs.
When opening or closing the front door (RH), DRIVER DOOR AJAR is displayed.
When opening or closing the front door (LH), PASSENGER DOOR AJAR is displayed.
When opening or closing the rear door (RH), RIGHT REAR/SLIDING DOOR AJAR is displayed.
When opening or closing the rear door (RH), RIGHT REAR/SLIDING DOOR AJAR is displayed.
When opening or closing the liftgate, DECKLID/HATCH AJAR is displayed.
Does the GEM PID indicate AJAR with a door opened and CLOSED with a door closed?
Yes
Go to Step 4.
No
Go to the next step.
2
INSPECT INOPERATIVE DOOR LATCH SWITCH
Disconnect the inoperative door latch switch connector.
Note
• When doors are closed, the door latch switch is also closed. (The circuit is grounded.)
Does the courtesy light turn on?
Yes
Replace the door latch switch.
No
Go to the next step.
3
INSPECT RELATED WIRING HARNESS BETWEEN INOPERATIVE DOOR LATCH SWITCH AND GEM FOR SHORT TO GROUND
Disconnect the GEM connector.
Measure the resistance between GEM and ground as follows:
• Front door (RH): Terminal 2F
• Front door (LH): Terminal 2H
• Rear door (RH): Terminal 2I
• Rear door (LH): Terminal 2G
• Liftgate: Terminal 2J
• Liftgate glass: Terminal 2E
Is the resistance more than 10,000 ohms?
Yes
Go to the next step.
No
Repair the related wiring harness.
4
INSPECT GEM OPERATION
Disconnect all the GEM connectors.
Inspect for the following items:
• Corrosion
• Terminal separation
Connect all the connectors and verify that their positions are correct.
Operate the system and inspect for any malfunction.
Is there any malfunction?
Yes
Replace the GEM.
No
The malfunction may result from loose connectors or corrosion.
Clear the DTC.
Repeat the DTC inspection.
