VISUAL INSPECTION CHART

WARNING: THE RESTRAINT SYSTEM DIAGNOSTIC TOOL IS FOR RESTRAINT SYSTEM SERVICE ONLY. REMOVE FROM VEHICLE PRIOR TO ROAD USE. FAILURE TO REMOVE COULD RESULT IN INJURY AND POSSIBLE VIOLATION OF VEHICLE SAFETY STANDARDS.

NOTE:
- If a seat equipped with a seat mounted side airbag system is being serviced the airbag system must be deactivated per the deactivation procedure contained in Air Bag Systems.
- Airbag simulators (restraint system diagnostic tools) MUST be installed under the seats in the side airbag to floor connector.
- Diagnostics or repairs are not to be performed on a side airbag system with the seat in the vehicle. Prior to attempting to diagnose/repair the side airbag system the seat must be removed from the vehicle and the restraint system diagnostic tool must be installed in side airbag connector at the floor connector. The restraint system diagnostic tool must be removed prior to operating the vehicle.
- Diagnostics may be performed on seat systems other than the side airbag system (lumbar, climate controlled, heated, power seat track) with the seat installed in the vehicle as long as the restraint system diagnostic tool is installed under the seat in the side airbag to floor connector.
- After diagnosing/repairing a seat system the restraint system diagnostic tool must be removed before operating the vehicle.

3. If the concern remains after the inspection connect the scan tool to the Data Link Connector (DLC) located beneath the instrument panel 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.
4. If the scan tool still does not communicate with the vehicle, refer to the scan tool manual.
5. Perform the DATA LINK DIAGNOSTIC TEST. Pinpoint Test PC (Precheck)
If the scan tool responds with:
- CKT9I4, CKT915 or CKT7O = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communication network (Information Bus).
- NO RESPINOT EQUIP for DSM, go to Pinpoint Test K. Test K: No Communication With the Module - Unable to Perform On-Demand Self-With the Driver Seat Module
- SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and perform self test diagnostics for the Driver Seat Module (DSM).
6. If the DTCs retrieved are related to the concern, go to DSM Diagnostic Trouble Code (DTC) Index to continue diagnostics. Diagnostic Trouble Code Descriptions
7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
