Test H: Passive Anti-Theft Systems Module Does Not Respond To NGS Tester
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2001 Ford Pickup, 2001 Ford F550 Super Duty, 2001 Ford F450 Super Duty, 2001 Ford Excursion, and 2001 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition switch to LOCK position. Disconnect 16-pin Passive Anti-Theft System (PATS) module connector. See Figure. Inspect PATS module connector for loose, damaged or corroded terminals. Repair connector as necessary. If PATS module connector is okay, go to next step.
- Measure resistance of Tan/Orange wire between PATS module connector C247 terminal No. 5 and Data Link Connector (DLC) terminal No. 2. See Fig 1. Also measure resistance of Pink/Light Blue wire between PATS module connector C247 terminal No. 4 and DLC terminal No. 10. If each resistance is less than 5 ohms, go to next step. If either resistance is 5 ohms or more, repair open in appropriate wire between PATS module and DLC.
- Disconnect PATS module connectors and inspect for loose, damaged or corroded terminals. Repair connector as necessary. Reconnect all connectors. Operate system to verify problem. If problem is present, replace PATS module. See PASSIVE ANTI-THEFT SYSTEM CONTROL MODULE under REMOVAL & INSTALLATION in appropriate PASSIVE ANTI-THEFT SYSTEMS article. If problem no longer exists, problem may have been caused by poor contact at connector.
