Inspection & Verification

WARNING: This page is about a different car, the 1999 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify customer's original problem by operating system in question. Inspect vehicle for any obvious electrical component wiring or connector damage. Inspect harness connectors for loose, damaged or corroded terminals. Check fuse No. 23 (20-amp) in instrument panel fuse box and related fuses for system in question.
  2. Inspect 16-pin Data Link Connector (DLC) pins for damage. See Fig 1. The DLC is located below driver's side of instrument panel, to the right of steering column. If pins are okay, go to next step. If pins are damaged, repair as necessary and proceed to next step.
  3. 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 switch is in RUN position. If NGS tester still does not communicate with vehicle, go to TEST N: NO MODULE/NETWORK COMMUNICATION  under SYSTEM TESTING. If NGS tester communicates with vehicle, perform data link diagnostic procedure. See DATA LINK DIAGNOSTIC TEST .
