2014 Ford Fusion Hybrid Stability Control lights

Maintenance/Repairs

Hello friends,

So my Ford Fusion hybrid has 110k miles on it. My wife was driving it today when the stability control lights both came on. I attempted to turn traction control on as it was showing off. The system won’t allow it to turn on. I hooked up my trusty obd scanner but no codes are being thrown. Nothing, nada. The wife said no noise happened, nothing out of the ordinary. I drove it after the fact and everything seemed fine, minus those 2 lights on the dash.

What, if any, ideas do you have? What should I examine and trouble shoot?

Thanks as always!

Most common problem is one of the wheel speed sensors is bad. You need forscan to read the ABS codes. https://forscan.org/home.html

Most code readers only read P codes from the engine control. This car has set a C code, or chassis error code. As @wolyrobb points out, you need a more comprehensive reader.

Forscan can do that and more. The PC version is free but requires a laptop and the proper $50 cable. The website shows you which one to buy. I use both the cell phone version and PC version.

Thinking about it… if the ABS light is not on, I’d guess the yaw and acceleration sensor has a problem, not a wheelspeed sensor. A wheelspeed sensor would take out the ABS as well.

There is also a phone app called OBDFusion that will probably read the code. It will require a separate OBD2 bluetooth dongle and you’d have to buy the app and a Ford-specific bundle of programming. The popular Torque app will not retrieve C-codes.

Any pros/cons on doing the pc version vs the phone one? Noticed 50 dollar difference in units but I use MACs so will have to use a Windows emulator to run the PC version.

If the phone version covers everything I might just spend the extra 50 and pay the 100 for the unit.

The PC version is more comprehensive but the phone app will read C codes.

I got these under ABS. Will have to do some research. But any early thoughts?

Went with the phone version for now. Posted a few pics of the ABS reading above. Not having much luck on the research front

That B300A code is telling you their is a broken wire from the ignition switch… or the BCM computer has failed which might be more likely

Everything I’m finding on BCM is related to alarm and keyless entry. Am I off track on this?

BCM where you recommend starting?
