Customer Question
Hi, We have a 2012 Ford...
Hi,
We have a 2012 Ford F-250 SD XLT Crew Cab, we have no turning signal and brake light on the rear drivers side. Have checked all the obvious things and haven't located the problem. Been doing a little reading and and lots of talk about the body control module. Any suggestions or things to try would be greatly appreciated.
Thanks, Bill

You are correct on thinking the BCM is the problem. The best way to make sure is to tap into the circuit for the drivers side rear turn signal/brake light circuit is to go to the connector at the BCM and tap into the wire coming from the BCM for that circuit and see if power is coming from the BCM on that wire. Below is the circuit and also the connector to look at. It is pin #12 in the connector. Also, if the BCM is the problem, it will need to be replaced and the new one programed to the vehicle properly so it functions properly.

We tested all the points mentioned and we didn't get any power from any of these points.
Any other suggestions to check why no power?
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 1 year ago

Then the BCM is the problem and will need to be replaced.

Ok, ballpark what's the cost of BCM?
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 1 year ago

Not sure on a good ball park price. I would say roughly about $400. Bu that is just a guess. I do not have access to the parts catalog at home.

Ok, we have another identical 2012 F250 with a blown motor and are going to use for parts. If we or can we take the BCM out of it and if so does it have to go to a dealer for programming after installed?
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 1 year ago

Yes, the dealership will have to program it to the vehicle for it to function properly.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
