Circuit/System Testing
WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the appropriate tail lamp assembly.
- Test for less than 5.0 ohms of resistance between the ground circuit listed below and ground.
- Pontiac - terminal GRND
- All others - terminal B
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Connect a test lamp between the supply voltage circuit listed below and the ground circuit.
- Pontiac - terminal Major
- All others - terminal A
- Ignition ON, cycle the PRNDL between the PARK and REVERSE positions. The test lamp should turn ON and OFF when changing between park and reverse.
- If the test lamp is always ON, test the supply voltage 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 supply voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the body control module.
- If all circuits test normal, test or replace the appropriate component.
