Air Bag Systems: Testing and Inspection

1. Disconnect and isolate the negative battery cable.
2. Connect the DRB III scan tool to the Data Link Connector, located at the left side of the steering column, at the lower edge of the instrument panel.
3. Turn the ignition key to ON position. Exit vehicle with the DRB III scan tool.
4. After checking that no one is inside the vehicle, connect the battery negative terminal.
5. Using the DRB III scan tool, read and record active Diagnostic Trouble Codes (DTC's).
6. Read and record any stored DTC's.
7. Refer to the proper Body Diagnostic Procedures if any DTC's are found in Step 5 or Step 6.
8. Erase stored DTC's if there are no active DTC's. If problems remain, DTC's will not erase. Refer to the proper Body Diagnostic Procedures to diagnose the problem. If the airbag warning lamp either fails to light with the ignition switch on, or the light goes on and stays on, there is a system malfunction. Refer to the proper Body Diagnostic Procedures to diagnose the problem.
