2001 Ford Explorer Sport/Explorer Sport Trac Service & Repair Manual

2001 ACCESSORIES & EQUIPMENT Passive Anti-Theft Systems - Explorer Sport & Explorer Sport Trac DESCRIPTION Passive Anti-Theft System (PATS) is designed to prevent driveaway thefts. System is passive in that it does not require any activity from user. System uses radio frequency identification technology to verify if proper key is being used to attempt to start vehicle. During each starting sequence, an encoded ignition key is interrogated by vehicle anti-theft electronics. If key's identification code is programmed into Powertrain Control Module (PCM), vehicle is capable of starting. If key's identification code is incorrect or missing, vehicle is prevented from starting. Early production models use a PATS transceiver module, and a PATS transceiver. PATS transceiver communicates with PATS transceiver module. PATS transceiver module determines if engine will be enabled to start. Late production models use a PATS transceiver and Powertrain Control Module (PCM). PATS transceiver communicates with PCM. PCM then determines if engine will be enabled to start. If PCM prevents vehicle from starting because of PATS, PCM will store a Diagnostic Trouble Code (DTC) in memory. PATS vehicle protection system consists of these components: anti-theft indicator (THEFT) light, PATS transceiver, encoded ignition key, module communications network and Data Link Connector (DLC). PATS have an unlimited key mode, that is intended for those customers who need more than 8 keys programmed. OPERATION ANTI-THEFT INDICATOR (THEFT) LIGHT THEFT indicator light located on right side of instrument cluster is used to prove out system operation status. Under normal operation THEFT indicator light will illuminate for 3 seconds when ignition switch is in RUN or START position, and then turn off. If a problem exists in PATS, THEFT indicator light will flash rapidly or illuminate constantly with ignition switch in RUN or START position. ENCODED IGNITION KEY When ignition switch is in RUN or START position, PATS initiates encoded ignition key interrogation process. PCM supplies both power and carrier signal to transceiver to momentarily energize ignition key. After energize NOTE: This article applies only to Explorer Sport and Explorer Sport Trac models. For 4-door Explorer testing procedures, see PASSIVE ANTI-THEFT SYSTEMS - EXPLORER & MOUNTAINEER article. NOTE: Explorer Sport and Explorer Sport Trac has 2 production levels: early production vehicles are built prior to July 24, 2000, and late production vehicles are built after July 24, 2000.

period has expired, key transmits its identification code to transceiver module. This encoded ignition key is much larger in size to accommodate the electronics located inside plastic cover. PASSIVE ANTI-THEFT SYSTEM TRANSCEIVER MODULE Transceiver receives ignition key identification code and sends signal to PATS transceiver module, on early production models. PASSIVE ANTI-THEFT SYSTEM TRANSCEIVER PATS contains circuitry to interface with vehicle electrical system, PATS transceiver, Module Communications Network (MCN) and THEFT indicator light. PCM stores ignition key codes in memory. PATS can be diagnosed through Data Link Connector (DLC). POWERTRAIN CONTROL MODULE On late production models, Passive anti-theft system uses PCM to enable or disable vehicle's engine. Within one second after engine starts, PCM must receive an enable signal or engine will not start.
