Supplemental Restraints Verification Test
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) - VERIFICATION TEST
The following procedure should be performed using a scan tool to verify proper supplemental restraint system (SRS) operation following the service or replacement of any SRS component.
WARNING: On vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, driver airbag, passenger airbag, side impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.
1. During the following test, the battery negative cable remains disconnected and isolated, as it was during the SRS component removal and installation procedures.
2. Connect the scan tool to the Data Link Connector (DLC).
3. Exit the vehicle but maintain contact with the scan tool.
4. Turn the ignition switch to the On position.
5. Check to be certain that there are no occupants in the vehicle, then reconnect the battery negative cable.
6. Using the scan tool, read and record any active (current) Diagnostic Trouble Code (DTC) data.
7. Next, use the scan tool to read and record any stored (historical) DTC data.
8. If any DTCs are found, refer to the appropriate diagnostic information.
9. Use the scan tool to erase any stored DTC data.
10. Turn the ignition switch to the Off position for approximately fifteen seconds, and then back to the On position. Observe the airbag warning indicator in the instrument cluster for proper operation. If a fault is detected, refer to the appropriate diagnostic information.
