Wrangler L4-2.5L VIN P (1999)
Air Bag: Testing and Inspection
A DRB scan tool is required for diagnosis of the airbag system. See the proper Diagnostic Procedures for more information.
16-Way Data Link Connector - Typical
1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the
instrument panel, outboard of the steering column.
2. Turn the ignition switch to the On position. Exit the vehicle with the DRB. Be certain that the DRB contains the latest version of the proper DRB
software.
3. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data.
4. Read and record any stored DTC data.
5. See the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4.
6. After completing the necessary repairs, try to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. See the
proper Diagnostic Procedures for the procedures to diagnose any stored DTC that will not erase.
7. With the ignition switch still in the On position, check to be certain that nobody is in the vehicle.
8. From outside of the vehicle (away from the air-bags in case of an accidental deployment) turn the ignition switch to the Off position for about ten
seconds, and then back to the On position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and
then go out. This indicates that the airbag system is functioning normally
NOTE: If the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. See the proper Diagnostic
Procedures to diagnose the problem.
