Test FC-25C - Injector #3 Control Circuit

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article.
NOTE: It may be necessary to remove intake plenum in the following steps.
  1. Reconnect junction block connector No. 3. Disconnect injector No. 3 connector. Turn ignition on. Using DRB-II, actuate Auto Shutdown (ASD) relay. Place DRB-II in voltmeter mode.
  2. Using DRB-II, check voltage of injector No. 3, ASD output wire (Dark Green/Orange wire). If voltage is less than 10 volts, repair ASD output wire for an open. Perform TEST VER-2. If voltage is more than 10 volts, go to next step.
  3. Turn ignition off. Using an external ohmmeter, check resistance of injector driver No. 3 wire (Yellow/White wire) between junction block connector No. 1 (junction block side) and injector No. 3 connector.
  4. If resistance is more than 5 ohms, repair injector driver No. 3 wire for an open. Perform TEST VER-2. If resistance is less than 5 ohms, replace injector No. 3. Perform TEST VER-2.
