Circuit/System Testing

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition ON, measure the voltage at the battery terminals and compare it with the scan tool ECM Ignition 1 Signal parameter. Verify that battery terminal and ignition 1 signal readings do not differ more than 1.0 volt.
    • If greater than specified value, test the ignition 1 and ground circuits for open/high resistance. If the circuits test normal, replace the ECM.
  2. Go to CHARGING SYSTEM TEST .
