Retrieving DTCS
Verify customers complaint by operating PATS. Ensure electronically coded ignition key is being used. Check for damaged ignition lock cylinder switch, damaged encoded ignition key or open fuses. Check for loose or corroded connectors, damaged wiring harness, damaged ignition switch or damaged transceiver module. Repair or replace components as necessary.
Connect New Generation Star (NGS) tester to Data Link Connector (DLC), located beneath instrument panel. Using NGS tester, preform data link diagnostics test. See MODULE COMMUNICATIONS NETWORK - PICKUP
article. If NGS tester displays NO RESP/NOT EQUIP for Passive Anti-Theft System (PATS) module, perform TEST 1: NO COMMUNICATION WITH PASSIVE ANTI-THEFT SYSTEM MODULE under SYSTEM TESTS.
If NGS tester responds with SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform PATS self-diagnostic test. If DTCs are retrieved, see PASSIVE ANTI-THEFT SYSTEM MODULE DTC INDEX table. If no DTCs are retrieved, repair system based on symptom. See SYSTEM TESTS .
