Test H: Passive Anti-Theft Systems Module Does Not Respond To WDS Or NGS Tester
- Turn ignition switch to LOCK position. Disconnect 16-pin Passive Anti-Theft System (PATS) module harness connector C252. 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 C252 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 C252 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 PASSIVE ANTI-THEFT SYSTEMS article. If problem no longer exists, problem may have been caused by poor contact at connector.
