Inspection & Verification
- Verify customer's original problem by operating system in question. Inspect vehicle for any obvious electrical component wiring or connector damage. Inspect connectors for loose, damaged or corroded terminals. Check related fuses for system in question.
- Inspect 16-pin Data Link Connector (DLC) pins for damage. See Fig 1. The DLC is located below driver's side of instrument panel, right of steering column. If pins are okay, go to next step. If pins are damaged, repair as necessary and proceed to next step.
- If problem is still present after performing inspection, connect New Generation Star (NGS) tester to DLC. Select vehicle to be tested from NGS tester menu. If NGS tester does not communicate with vehicle, ensure program card is properly installed. Check NGS tester cable connections and ensure ignition is on. If NGS tester still does not communicate with vehicle, go to TEST L: NO MODULE/NETWORK COMMUNICATION under TESTING. If NGS tester communicates with vehicle, perform data link diagnostic procedure. See DATA LINK DIAGNOSTIC TEST.
