How do you turn off red spanner on transit?

To turn off the red spanner warning light on a Transit vehicle, first, check the vehicle's diagnostic system for any active faults, as the light indicates a maintenance issue. Once the issue is resolved, you can reset the warning by using a diagnostic scanner or by disconnecting the vehicle's battery for a few minutes. If the light persists after addressing any faults, consult the owner's manual or a professional mechanic for further assistance.
