  1. 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. If problem is found, replace or repair as necessary. If no problem is found, go to next step.
  2. Inspect 16-pin Data Link Connector (DLC) pins for damage. See Figure. DLC is located under instrument panel between steering column and the radio. See Figure. If pins are okay, go to next step. If pins are faulty, repair or replace as necessary. After repair, go to next step.
  3. If problem is still present after performing inspection or repairs, connect Worldwide Diagnostic System (WDS) tester or New Generation Star (NGS) tester to DLC. See Figure. Select vehicle to be tested from diagnostic tool menu. If diagnostic tool does not communicate with vehicle, ensure program card is properly installed. Check diagnostic tool tester cable connections and ensure ignition switch is in RUN position. If diagnostic tool still does not communicate with vehicle, perform TEST H: NO MODULE/NETWORK COMMUNICATION  under SYSTEM TESTS. If diagnostic tool communicates with vehicle, perform data link diagnostic procedure. See DATA LINK DIAGNOSTIC TEST .
