Circuit/System Testing

  1. Measure the voltage at the battery terminals and compare it with the Ignition 1 Signal parameter in the ECM data list. Verify that battery and Ignition 1 signal readings do not differ more than 1 volt.
    • If greater than 1 volt test the Ignition 1, ground circuits of the ECM for open/high resistance or replace the ECM.
  2. Go to Charging System Test .
