- When checking air bag system operation (also known as prove out) and upon completion of each diagnostic test, check for faults in air bag system. To check system, turn ignition switch to RUN position. If AIR BAG warning light illuminates for 6 seconds and then goes out, air bag system is functioning properly and no faults exist.
- If a fault is detected in air bag system during initial system check, AIR BAG warning light will either 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. Flashing may not occur for about 30 seconds after ignition switch is turned to ON position while ECS completes testing of SRS. Number of flashes represents a code number used to diagnose air bag system. See DIAGNOSTICS .
- If a system fault exists and AIR BAG warning light fails to light, an audible tone will be heard, indicating AIR BAG warning light is inoperative and system service is required. AIR BAG warning light will need to be repaired before diagnosis can be continued.
