Thank You!Sure thing...the dealer found the problem and fixed it and I have not had the warning message since. Here is exactly what they wrote on the repair form, share it with your dealer and maybe it will help them:
@Timinpgh - thanks again - I was finally able to bring my Bronco into Ford dealer and handed them your repair sheet. Same issue on mine - fixed it in about 30 minutes and back on the road. Thanks again
Oh great, glad I could help! Hopefully somebody at Ford is taking note. If we know of 2 such cases, there are probably 20. Somebody needs to talk to the assembly person in charge of that and let them know there is a problem
Any idea which fuse c1100b is? I'm having the same problem on mine. Would rather check the fuse myself first before taking it in for further diagnosticsSure thing...the dealer found the problem and fixed it and I have not had the warning message since. Here is exactly what they wrote on the repair form, share it with your dealer and maybe it will help them:
No I do not, one of the fuses in the main terminal box under the hood. But, it was not the fuse itself that was the problem. It was underneath where the corresponding wire clips in to the fuse terminal, so you would have to take the box apart to get to it.
I’ll probably take it in. Everything runs and works properly, just the message pops up like the computer thinks something is wrong but actually isn’t. I’ve already tested the battery multiple days off and on at idle. Can’t be the alternator because it battery only operations would’ve killed the truck off by now. Battery light doesn’t come on. Voltage sits in a good range while driving.
Yup, that sounds just like mine. I would do like Kenamu did in the post above, print out my repair sheet and give it to the service department, it might save them some time and get you back on the road more quickly. Good luck and please report back on the result! PS: I have not had any problems since they fixed it, and that was 2000+ miles ago.
Well I disconnected the negative terminal, went around and tightened any ground connections I saw, and reseated some of the fuses including the 3A battery sensor fuse on the positive terminal side of the battery. So far so good.
I've got a MyQ and I love it for phone-managed access, open/close from anywhere, Amazon Key (in garage delivery) support, etc. I recommend pairing it with a garage cam and/or some level of security for the garage/house door.
Interesting you would get it after so many miles. Do you have ForSCAN? If so see if you are getting the same error code that I had: BCM-B11D8080A
So it turns out the issue is a coolant control valve for the transmission fluid heater that is slowly dripping onto the battery control sensor. Okay to drive until the parts come in next week. There is an updated TSB on this issue as well. TSB 23-2196 was superseded by this current one 23-2368.
“Coolant control valve” for the “transmission fluid heater” and a “battery control sensor” ???? These Broncos are far too complicated for their own good, sheesh…
Interesting...that is more consistent with something that would happen after 15k miles. Looks like an easy fix once they have the part. Here is the repair process they reference in the TSB
