Door Lock Switch Malfunction
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 door lock switch.
- Test for less than 1.0 ohm between the ground circuit terminal 3 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify the scan tool Door Lock Sw parameter is Inactive.
- If not the specified parameter, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the BCM.
- Verify the scan tool Door Unlock Sw parameter is Inactive.
- If not the specified parameter, test the signal circuit terminal 2 for a short to ground. If the circuit tests normal, replace the BCM.
- Install a 3 amp fused jumper wire between the signal circuit terminal 1 and ground. Verify the scan tool Door Lock Sw parameter is Active.
- If not the specified parameter, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
- Install a 3 amp fused jumper wire between the signal circuit terminal 2 and ground. Verify the scan tool Door Unlock Sw parameter is Active.
- If not the specified parameter, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
- If all circuits test normal, test or replace the door lock switch.
