DESCRIPTION & OPERATION
| WARNING | Accidental air bag deployment is possible. Personal injury may result. Read and follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS before working on air bag system or related components. |
The Supplemental Restraint System (SRS), also known as air bag system, is designed to provide increased accident protection for driver and passengers by deploying front air bags and seat belt pretensioners in a front-end collision and side air bags and side impact head protection system when side impact is detected.
Main components of the air bag system include air bag control module, driver-side air bag module, passenger-side air bag module, side air bag modules, side impact head protection modules, side air bag crash sensors, seat belt pretensioners, AIR BAG warning light and contact ring (clockspring).
Air bag control unit is capable of system self-diagnosis. Air bag system components are monitored electrically. Any interferences in operation can be detected. These interferences (faults) are then stored in air bag control module memory. Diagnosis can only be performed when DIS-MoDiC tester is connected to vehicle's Data Link Connector (DLC).
SYSTEM OPERATION CHECK
Turn ignition switch to ON position. If AIR BAG warning light should illuminate for 6-10 seconds then turn off. If AIR BAG warning light illuminates for 6-10 seconds and turns off, air bag system is functioning properly. If AIR BAG warning light illuminates for 6-10 seconds and turns off, then illuminated again or remains illuminated, a fault in air bag system has been detected. If AIR BAG warning light illuminates while operating the vehicle, fault in air bag system has been detected. If AIR BAG warning light fails to illuminate, this indicates bulb or wiring is faulty.
