Test NS-6C - Correcting No Response Condition

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  section.
  1. Inspect ENGINE fuse in Power Distribution Center (PDC). If fuse is blown, go to next step. If fuse is not blown, repair open Red/White wire between Powertrain Control Module (PCM) connector terminal No. 3 and battery positive (power supply). Perform TEST VER-1.
  2. Turn ignition off. Disconnect Auto Shutdown (ASD) relay and fuel pump relay. Using scan tool in ohmmeter mode, check resistance on PCM connector terminal No. 3 (Red/White wire). If resistance is more than 5 ohms, go to next step. If resistance is less than 5 ohms, repair short to ground in Red/White wire. Perform TEST VER-1.
  3. Using scan tool, check resistance of ASD relay connector Dark Green/Orange wire. If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, go to TEST NS-6D.
  4. Disconnect ignition coil connector. Using scan tool, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, replace ignition coil. Perform TEST VER-1. If resistance is less than 5 ohms, go to next step.
  5. Disconnect generator field connector. Using scan tool, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, repair short to ground in generator. Perform TEST VER-1.
  6. If resistance is less than 5 ohms, disconnect fuel injector harness connector. Using scan tool, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, repair short to ground in fuel injector harness. Perform TEST VER-1. If resistance is less than 5 ohms, repair short to ground in Dark Green/Orange wire between ASD relay connector and fuel injector harness. Perform TEST VER-1.
