WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the inoperative door latch assembly.
- Test for less than 10.0 ohms between the appropriate ground circuit terminal listed below and ground.
- Driver door latch ground circuit terminal 5
- Passenger door latch ground circuit terminal 3
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify the scan tool Door Open Switch parameter is INACTIVE.
- If the scan tool displays ACTIVE, test the appropriate signal circuit terminal listed below for a short to ground. If the circuit tests normal, replace the appropriate door control module.
- Driver door open switch signal circuit terminal 7
- Passenger door open switch signal circuit terminal 2
- If the scan tool displays ACTIVE, test the appropriate signal circuit terminal listed below for a short to ground. If the circuit tests normal, replace the appropriate door control module.
- Install a 3A fused jumper wire between the appropriate signal circuit terminal listed below and ground. Verify the scan tool Door Open Switch parameter is ACTIVE.
- Driver door open switch signal circuit terminal 7
- Passenger door open switch signal circuit terminal 2
- 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 appropriate door control module.
- If all circuits test normal, replace the inoperative door latch assembly.
