Test FC-39B - Auto Shutdown Relay Control Circuit

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article.
  1. Disconnect Auto Shutdown (ASD) Relay. Place DRB-II in voltmeter mode. Using DRB-II, check voltage of ASD relay connector terminal "B" battery feed wire (Red/White wire). If voltage is less than 12 volts, repair battery feed wire to ASD relay. Perform TEST VER-2. If voltage is more than 12 volts, go to next step.
  2. Disconnect Powertrain Control Module (PCM). Using an external ohmmeter, check resistance of relay control wire (Dark Blue/Yellow wire) between ASD relay connector terminal "C" and PCM connector terminal No. 51. If resistance is more than 5 ohms, repair open ASD relay control wire. Perform TEST VER-2.
  3. If resistance is less than 5 ohms, reconnect PCM. Install a known good ASD relay. Attempt to start engine. If engine starts and runs, replace original ASD relay. Perform TEST VER-2. If engine does not start and run, replace PCM. Perform TEST VER-2.
