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 OFF, disconnect the harness connector at the EBCM.
  2. Ignition OFF, test for less than 1.0 ohm of resistance between the ground circuit and ground.
    • If the greater than the specified range, test the ground circuit for an open / high resistance. If the circuit tests normal replace the EBCM.
  3. Measure the voltage at the battery terminals.
  4. Ignition ON, observe the scan tool EBCM ignition voltage parameter. Verify that battery terminal voltage and ignition voltage readings do not differ more than 1-volt.
    • If greater than the specified value, test the ignition voltage circuit for a short to ground or an open / high resistance. If the circuit tests normal replace the EBCM.
  5. Go to CHARGING SYSTEM TEST
