WARNING: This page is about a different car, the 2002 Ford Pickup, 2002 Ford F550 Super Duty, 2002 Ford F450 Super Duty, and 2002 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition switch to LOCK position. Deactivate air bag system. See AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. Disconnect Restraints Control Module harness connector C2041. Inspect RCM harness connector for loose, damaged or corroded terminals. Repair connector as necessary. If RCM harness connector is okay, go to next step.
- Measure resistance of Light Blue/White wire between RCM harness connector C2014 terminal No. 5 and Data Link Connector (DLC) terminal No. 7. See Figure and Fig 1 . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Light Blue/White wire between DLC and RCM. See WIRING DIAGRAMS .
- Disconnect all RCM connectors and inspect for loose, damaged or corroded terminals. Repair connector as necessary. Reconnect all connectors. Operate vehicle to verify problem. If problem is present, replace RCM. See RESTRAINTS CONTROL MODULE (RCM) under REMOVAL & INSTALLATION in AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. If problem no longer exists, problem may have been caused by poor contact at connector.
