So I just installed my leveling kit on my 2019, after install it is throwing a whole bunch of codes, and abs light is on.

hill decent control fault
service advance trac,
hill start assist not available
pre collision assist not available

anybody have an idea?

 

Wow that’s interesting. I’ve never heard of that before . I’m curious if anyone else has this error as I didn’t (and glad I didn’t) .. sorry to hear that bud, hopefully someone else can help you.

you may wanna give some more info like what kind of leveling kit , you install it ? The process etc.. maybe someone can point something out

 

Look at your front wheel speed sensors. Check the sensor, wires, and the plug up near the frame.

 

Oh...and if you have access to Forscan or a good code reader you should be able to see the fault code.

 

Is there an ABS sensor that might have gotten unplugged? Look for a hanging plug by the wheel hub?

 

May have a broken wire from one of the sensors too. If you're not super careful when tilting the steering knuckle out, that sensor wire could be put in a bind bad enough, the conductor could be broken.

 

So I uninstalled the leveling kit and when I turned the truck on they were still there, but then I backed it out of the garage and they all disappeared. I am confused as hell. I have no clue what it is doing.

 

By any chance did you start the truck in the air and put it in drive without the wheels on the ground.

 

Not discounting your knowledge at all, so don't take offense, but where are you going with this. Sometimes I'm not careful enough, and I actually learn something.

 

It sounds like a wheel speed sensor to me. There really aren't many electronic things in the vicinity that could have been affected by installing a level. And a bad or no reading from the wheel speed sensor would produce those errors.

I've also heard that you should disconnect the battery when installing a level, something about the electronics in the steering system. Not sure how critical that is though.
