Circuit/System Testing

  1. Ignition OFF. Disconnect the harness connector of the ECM.
  2. Probe the ground circuits with a test lamp that is connected to B+. The test lamp should illuminate.
    • If the test lamp does not illuminate, then test the ground circuit for an open/high resistance.
  3. Test for 11-14 volts between the battery positive voltage and the ground circuits of the ECM.
    • If not within the specified range, test the battery positive voltage circuits for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the ECM.
