WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
- When checking air bag system operation (also known as 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 about 6 seconds and then goes out, air bag system is functioning properly and no fault exists.
- If a fault is detected in air bag system during initial system check, AIR BAG warning light will flash a code sequence, 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 AIR BAG warning light either fails to light or stays on continuously, go to DIAGNOSTIC SYMPTOMS table.
- 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 out and service is required. AIR BAG warning light will need to be repaired before diagnosis can be continued.
