Hey guys, I have a 2003 Ford Explorer Sport with a manual transmission and 100,000 miles on it. I recently started getting an intermittent airbag code 51 combined with the seat belt light flashing and chiming. It doesn't do it all the time. Maybe every 1 out of 5 times that I start and drive the car. Any help that would point me in the right direction will be greatly appreciated. Thanks in advance.
