Test FC-30B - 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 ASD relay. Using DRB-II, check voltage on ASD relay connector, battery feed circuit (Red/White wire). If voltage is less than 12 volts, repair open in Red/White wire. Perform VERIFICATION PROCEDURE VER-2. If voltage is more than 12 volts, turn ignition off.
  2. Disconnect Powertrain Control Module (PCM) connector. Put DRB-II in ohmmeter mode. Using DRB-II, check resistance of ASD relay connector, output circuit (Dark Green/Orange wire). If resistance is more than 5 ohms, repair open in Dark Green/Orange wire. Perform VERIFICATION PROCEDURE VER-2.
  3. If resistance is less than 5 ohms, reconnect PCM connector. Install a known good ASD relay. If engine will start and run, replace original ASD relay. Perform VERIFICATION PROCEDURE VER-2. If engine will not start and run, replace PCM. Perform VERIFICATION PROCEDURE VER-2.
