NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY  . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article.
  1. Turn ignition switch to OFF position. Disconnect and inspect SBEC connector terminals. Repair connector terminals if damaged. Perform VERIFICATION PROCEDURE VER-2.
  2. If connector terminals are okay, place DRB-II in ohmmeter mode. Probe SBEC connector terminal No. 5 (Black/White wire). If resistance is more than one ohm, repair Black/White wire for an open to ground. Perform VERIFICATION PROCEDURE VER-2. If resistance is less than one ohm, probe terminal No. 11.
  3. If resistance is more than one ohm, repair Black/Tan wire for an open to ground. Perform VERIFICATION PROCEDURE VER-2. If resistance is less than one ohm, probe SBEC connector terminal No. 12 (Black/Tan wire). If resistance is more than one ohm, repair Black/Tan wire for an open to ground. Perform VERIFICATION PROCEDURE VER-2.
  4. If resistance is less than one ohm, place DRB-II in voltmeter mode. Turn ignition switch to ON position. Probe SBEC connector terminal No. 9 (Dark Blue wire). If voltage is less than 10 volts, repair open Dark Blue wire. Perform VERIFICATION PROCEDURE VER-2. If voltage is more than 10 volts, reconnect SBEC connector. Test is complete.
