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 theft deterrent module (TDM).
  2. Ignition OFF, test for less than 1.0 Ω of resistance between the ground circuit terminal 3 and ground.
    • If greater than the specified range, test the ground circuit for an open / high resistance. If the circuit tests normal replace the TDM.
  3. Measure and record the voltage at the battery terminals. Ignition ON, measure the voltage between the ignition voltage circuit terminal 2 and ground. Verify that the voltage readings do not differ more than 1 volt.
    • If greater than specified value, test the ignition voltage circuit for a short to ground or an open / high resistance. If the circuits test normal, replace the TDM.
  4. Refer to CHARGING SYSTEM TEST .
