WARNING: This page is about a different car, the 2002 Ford RV Cutaway, 2002 Ford Econoline, 2002 Ford E450 Super Duty, and 2002 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Electronic Crash Sensor (ECS) module may also be referred to as air bag diagnostic monitor.
- Turn ignition switch to OFF position. Deactivate air bag system. See AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. Disconnect ECS module Gray 28-pin harness connector C2209 located behind right kick panel. Inspect connector for loose, damaged or corroded terminals. If connector is okay, go to next step. If connector is faulty, repair connector as necessary. Retest system operation.
- Measure resistance of Light Blue/White wire between DLC terminal No. 7 and ECS module Gray 28-pin harness connector C2209 terminal No. 19. See Figure and Fig 1 . If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, replace ECS module. Retest system operation.
- Disconnect Black 14-pin in-line connector C210 located behind right kick panel. Inspect connector for loose, damaged or corroded terminals. If connector is okay, go to next step. If connector is faulty, repair connector as necessary. Retest system operation.
- Measure resistance of Light Blue/White wire between DLC terminal No. 7 and Black 14-pin in-line connector C210 terminal No. 2. See Figure and Fig 2 . If resistance is less than 5 ohms, repair open in Light Blue/White wire between Black 14-pin in-line connector C210 (female side) and ECS module Gray 28-pin harness connector C2209. Retest system operation. If resistance is 5 ohms or more, repair open in Light Blue/White wire between Black 14-pin in-line connector C210 (male side) and DLC. Retest system operation.
