Inspection and Verification

INSPECTION AND VERIFICATION

CAUTION: Keep objects a safe distance from the luggage compartment lid when operating. Make sure objects of any kind are not placed on the luggage compartment lid. Verify the lid opening area and top of lid is clear of any objects or passengers before operating the luggage compartment lid.

NOTE: The luggage compartment lid motor is equipped with an optical sensor that the module uses to determine if the lid is closing on foreign materials based on lid speed. If the module detects this occurring, power and ground will be reversed to the lid motor and the lid will open.

1. Verify the customer concern by operating the luggage compartment lid using the 4 different methods (driver door trim panel button, transmitter button, keyless entry keypad and key) to duplicate the concern.

Visual Inspection Chart:

2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. Verify the grounds (G402, G403, and G404) are clean, tight, and free from corrosion.
4. Monitoring the PIDs in the luggage compartment lid module can verify the DDM is sending the lid-open signal to the lid module. They can also be used to determine if the latch switches, the lid switches and the lid motor sensors are all providing the luggage compartment lid module with the correct and necessary information to operate the system. The VSO input can shut the system down if there is a signal indicating 5 kph (3 mph) or more.
5. If the electrical lid operation is ok, but the key is ineffective, refer to Locks.
6. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) located under the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
- check that the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.

7. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
8. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- SCP or ISO circuits fault; all electronic control units no response/not equipped, refer to Information Bus (Module Communications Network).
- No response/not equipped for luggage compartment lid module, GO to Pinpoint Test A. Test A: No Communication With the Luggage Compartment Lid Module
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the luggage compartment lid module.

9. If the DTCs retrieved are related to the concern, go to the Luggage Compartment Lid Module Diagnostic Trouble Code (DTC) Index. For lighting control module (LCM) concerns, refer to Body Control Systems (Multifunction Electronic Control Module) for a complete DTC index. Diagnostic Trouble Code Tests and Associated Procedures
10. If no DTCs related to the concern are retrieved, GO to Symptom Chart. Symptom Related Diagnostic Procedures
