How to Disable the Seat Belt Alarm on a F-350 Fordby Susan Davis
Although the seat belt alarm is made for safety, it can certainly be annoying. There are times when you want to be in your Ford F-350 pickup truck without putting on your seat belt, like when you are trying to listen to a football game while you are waiting in your truck for someone, but that seat belt alarm just won't quit. Luckily, there is a process that you can do yourself to disable your Ford's seat belt alarm. Follow the steps exactly, and the alarm will be disabled. The process is the same for all F-series Fords.
Set the parking brake on your Ford F-350.
Put your truck in park and ensure that all the doors are closed and the seat belts are unbuckled. Do not turn on the ignition or turn on the headlights.
Turn the ignition on. Don't start the truck. Wait for the seat belt warning light to go off on your dashboard.
Buckle and unbuckle the driver's seat belt three times. The belt should end up being unbuckled.
Turn the headlights on and then turn them right off.
Buckle and unbuckle the driver's seat belt three more times, ending up with it unbuckled. On your dashboard, you should see the safety belt warning light come on for a few seconds.
Buckle and then immediately unbuckle the driver's seat belt when the seat belt warning light turns off. The warning light on your Ford's dashboard will start flashing. When it stops, the process is complete and your alarm is disabled.
