Inspection & Verification
- Verify customer's original complaint by operating system in question. Inspect vehicle for any obvious electrical component wiring or connector damage. Inspect connectors for loose, damaged or corroded terminals. Inspect related fuses for system in question.
- Inspect 16-pin Data Link Connector (DLC) pins for damage. See Fig 1. DLC is located under driver's side of instrument panel, to left of steering column.
- Turn ignition switch to LOCK position. Connect NGS tester to DLC. Turn ignition switch to ON position. Select vehicle to be tested from NGS tester menu. If NGS tester does not communicate with vehicle, ensure program card is properly installed. Inspect NGS tester cable connections and ensure ignition is on. If NGS tester still does not communicate with vehicle, perform TEST F: NO MODULE/NETWORK COMMUNICATION under SYSTEM TESTS. If NGS tester communicates with vehicle, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST .
