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 appropriate tail lamp assembly.
  2. Test for less than 1.0 Ω of resistance between the ground circuit terminal B and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Connect a test lamp between the voltage supply circuit terminal A and the ground circuit terminal B.
  4. Ignition ON, place the PRNDL in the reverse position. The test lamp should turn ON and OFF when changing between park and reverse.
    • If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the body control module.
    • If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the body control module.
  5. If all circuits test normal, test or replace the appropriate component.
