Warning light?

[Blackbite]

Yesterday this icon popped up after the car reached temp. I drove it twice yesterday with the same result. I looked through the owners manual and could not find the designation. Can anyone provide some help?

Maybe electric park brake malfunction

Definitely looks like it signifies something about brakes and an electrical problem.

That is what I thought initially, but the electric brake is a slightly different icon? But maybe?

check to see if any debris got in there, did you change tire size?

I checked to see if anything was dragging on the rotor, doesn’t appear to be. Earlier today I set the parking brake and disengaged. I moved the car a bit in the drive it’s currently not on. I will go for a short drive later.
I do have an 18” MT ET R currently on the rear. The tire size could cause the light to trip?

From what I've been told its possible. Do you have a programmer in the car? I ask because I have an Nguage and in the settings you are able to change tire height ect.

Charging system (alternator) would be my guess.

Edit: disregard, see below.

That would have been good to state in the first post.
Is tire height exactly the same as stock?

If different than stock height the computer may think you are in a traction limited condition all the time if you haven’t compensated for it with a custom tune. That would cause issues and possibly the light.

Found this on the Ford indicator light site:

Didn’t realize the tire size would throw an Ebrakes light? Car is getting retuned in 2 weeks. Can easily adjust it then.

The light is because of tire size difference. Why it shows the ebrake warning light confused me too. 100% tire size differences. I put DR on and got the same light.....put regular tires back on and gone away. There is no fixing or adjusting this, out side of having same tire diameters, or someone tuning it. And if you did fix it for the DR then it would throw the error for regular tires.

Thanks for the info. Now that I know what is causing it I’m not to worried. I agree, tuning it out may not be the best solution, since I won’t always have the DR’s on the car.

If you get the correct formula, you can use Forscan to change the tire size in the BCM yourself.

Are the front tires the SAME O/D SIZE as the rear tires? I run 325's on ALL 4 tires and DON'T have a LIGHT!!!
