Circuit/System Testing
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
Seat Belt Indicator Always ON
- Ignition OFF, disconnect the harness connector at the driver seat belt buckle.
- Ignition ON, verify the scan tool Driver Seat Belt Switch parameter is Unbuckled.
- If not the specified value, test the signal circuit terminal B for a short to ground. If the circuit tests normal, replace the SDM.
- If all circuits test normal, test or replace the driver seat belt buckle.
Seat Belt Indicator Always OFF
- Ignition OFF, disconnect the harness connector at the driver seat belt buckle.
- Connect a fused jumper wire between the seat belt switch signal circuit terminal B and ground.
- Ignition ON, verify the scan tool Driver Seat Belt Switch parameter is Buckled.
- If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the SDM.
- Connect a fused jumper wire between the seat belt switch signal circuit terminal B and the low reference terminal A.
- Verify the scan tool Driver Seat Belt Switch parameter is Buckled.
- If not the specified value, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the SDM.
- If all circuits test normal, test or replace the driver seat belt buckle.
