Circuit/System Testing
WARNING: This page is about a different car, the 2010 GMC Terrain and 2010 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Circuit/System Verification must be performed before Circuit/System Testing.
- Ignition OFF, disconnect the harness connector at the S48C Multi-Function Switch - Instrument Panel 1.
- Test for less than 5 Ω between the ground circuit terminal 1 and ground.
- If greater than the specified value, test the ground circuit for an open/high resistance.
- Ignition ON, verify the scan tool BCM Traction Control Switch parameter is Inactive.
- If not the specified value, test the signal circuit for a short to ground. If the circuit tests normal, replace the K9 Body Control Module.
- Install a 3A fused jumper wire between the signal circuit terminal 3 and ground.
- Verify the scan tool BCM Traction Control Switch parameter is Active.
- 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 K9 Body Control Module.
- If all circuits test normal, test or replace the S48C Multi-Function Switch - Instrument Panel 1.
