- Whenever checking air bag system operation, and at completion of each diagnostic test, check for faults in air bag system. To check system, turn ignition switch to ON position. If AIR BAG warning light illuminates 4-8 seconds then goes out, air bag system is functioning properly and no fault codes exist.
- If a fault code is detected in air bag system during initial system check, AIR BAG warning light will fail to light, stay on continuously, or flash a code sequence. If AIR BAG warning light flashes, indicating a fault in system, count number of flashes after fault code has cycled twice. Number of flashes represents a code number used to diagnose air bag system. See DIAGNOSIS & TESTING.
- If a system fault code exists and AIR BAG warning light fails to illuminate, an audible tone will be heard indicating AIR BAG warning light is out and service is required.
