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.

SELF-DIAGNOSTIC SYSTEM
Connect New Generation Star (NGS) tester to Data Link Connector (DLC), located beneath instrument panel. Using NGS tester, preform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If NGS tester responds with CKT914, CKT915 or CKT70=ALL ECUS NO RESP/NOT EQUIP, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If NGS tester displays NO RESP/NOT EQUIP for Passive Anti-Theft System (PATS) module, perform TEST A: NO COMMUNICATION WITH PATS MODULE under SYSTEM TESTS.
If NGS tester responds with SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform PATS module self-test. If any DTCs are present, perform appropriate test. See PATS MODULE DTC INDEX table. Codes listed in this table are only for testing covered in this article. For complete DTC listing, see MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If no DTCs are present, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
