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 1.0 volt.
    • If greater than 1.0 volt, test the ignition 1 ground circuits of the ECM for high resistance or replace the ECM.
  2. Go to Charging System Test .
