Test M: No Module/Network Communication - No Power To NGS Tester Through DLC

WARNING: This page is about a different car, the 2000 Mercury Mountaineer and 2000 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect NGS tester connector for loose, damaged or corroded terminals. Repair as necessary and retest system for normal operation. If connector is okay, go to next step.
  2. Turn ignition off. Inspect Data Link Connector (DLC) for physical damage, bent terminals or corrosion. Repair as necessary and retest system for normal operation. If connector is okay, go to next step.
  3. Measure voltage between ground and DLC terminals No. 16. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair Orange wire between DLC and central junction box fuse No. 17 (25-amp). Retest system for normal operation.
  4. Measure resistance between ground and DLC terminals No. 4 (Black wire) and No. 5 (Black/White wire). If each resistance is less than 5 ohms, repair or replace scan tool. Retest system for normal operation. If either resistance is 5 ohms or more, repair appropriate wire between DLC and ground.
