Inspection and Verification

INSPECTION AND VERIFICATION

1. Verify the customer concern.

Visual Inspection Chart:

2. Visually inspect for obvious signs of mechanical or electrical damage.
3. Visually inspect the front and rear cables for damage. The cable may be abraded or frayed, resulting in increased door opening/closing effort. The increased effort may trigger the obstacle detection and cause the door to reverse unintentionally. The cable may be frayed due to incorrect assembly of the front and/or rear cable guide assembly. Circumferential cracks in the plastic coating do not count as a failure.
4. Visually inspect for smooth manual operation of the door. Verify lubrication in the upper and lower tracks. Verify that no localized tight conditions exist between the tracks and roller, causing a binding condition. Increased localized efforts may trigger an obstacle detection and cause the door to reverse unintentionally, or cause the unlatch actuator to deactivate before the door latch clears the latch striker as the door begins to open.
5. Visually inspect the center track fasteners by making sure the head of each fastener is correctly seated into the track.
6. Verify the PSD center hinge does not have a bumper attached. This bumper should only be present for a manual sliding door. If this bumper is present on a power door system, remove it. Also on the PSD center hinge is a clip-on rubber bumper used during the manufacturing process to protect the paint. This bumper may be removed to improve door closing efforts.
7. The battery voltage must be at normal operating levels in order for the PSD to open and close correctly. Make sure the battery and charging systems are operating correctly before carrying out the PSD self-test.
8. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
9. If the cause is not visually evident, connect the scan tool to the data link connector (DLC) and select the vehicle to be tested from the scan tool menu. If the scan 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.

10. If the scan tool tester still does not communicate with the vehicle, refer to the Scan Tool Operating Manual.
11. Carry out the scan tool data link test. If the scan tool responds with:
- SCP or ISO circuit fault; all electronic control units no response/not equipped, refer to Information Bus (Module Communications Network).
- No response/not equipped for LH PSD module, GO to Pinpoint Test A. Test A: No Communication With The Left Power Sliding Door Module (LPSDM)
- No response/not equipped for RH PSD module, GO to Pinpoint Test B. Test B: No Communication With The Right Power Sliding Door Module (RPSDM)
- No response/not equipped for the SJB, refer to Body Control Systems (Multifunction Electronic Control Module).

- NOTE: In order to carry out the PSD module self-tests, the overhead console on/off switch must be in the ON position. The PSD must be completely closed and unlocked. The vehicle must be in PARK and the ignition key must be in the ON position. For the LH side PSD only, the fuel filler door must be completely closed.

SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the LH side PSD module, the RH PSD module and the SJB.

12. If the DTCs retrieved are related to the concern, go to the appropriate DTC index.
13. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue the diagnostics. Symptom Related Diagnostic Procedures
