System Operation Check
- When checking air bag system operation (also called prove out system), 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 4-8 seconds and then goes out, air bag system is functioning properly and no fault codes 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. Number of flashes represents a code number used to diagnose air bag system. See DIAGNOSTICS .
- If a system fault exists and primary AIR BAG warning light fails to light, secondary AIR BAG warning light to indicate need for system service.
