Test D: Restraint Control Module Does Not Respond To NGS Tester
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
To avoid accidental deployment and possible personal injury, backup power supply must be depleted before repairing or replacing any air bag restraint system components. Disconnect negative battery cable and auxiliary power supplies, if equipped. Wait one minute for backup power supply energy to deplete.
- Turn ignition switch to LOCK position. Deactivate air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. Disconnect Restraint Control Module (RCM) 26-pin harness connector C2041. RCM is located behind right side of instrument panel. Inspect harness connector for loose, damaged or corroded terminals. If harness connector is okay, go to next step. If harness connector is damaged, repair as necessary.
- Measure resistance in Light Blue/White wire between RCM harness connector C2041 terminal No. 5 and Data Link Connector (DLC) terminal No. 7. See Figure and Fig 1 . If resistance is 5 ohms or less, replace RCM. See RESTRAINT CONTROL MODULE in REMOVAL & INSTALLATION. If resistance is more than 5 ohms, repair Light Blue/White wire between RCM harness connector C2041 and DLC. See WIRING DIAGRAMS .
