Ground Circuit Check

  1. Connect ohmmeter between ground and breakout box terminal No. 20, then between ground and breakout box terminal No. 29. Ohmmeter should indicate about zero ohms. If about zero ohms is not present, check control unit grounds.
  2. Connect ohmmeter between breakout box terminal No. 20 and breakout box terminals No. 8, 12, 14, and 23. Ohmmeter should indicate about zero ohms in all cases. If reading is too high, repeat test using new fuel injection ECU.
