After getting home from a 90 mile highway trip that was normal and parking in our driveway overnight I started the pickup the next day and get warning lights for ABS, Brakes and Tracing System. The computer screen gives the following warnings in this order: Hill Descent Control FAULT, Check Brake System, Service AdvanceTrac and then repeats those three warnings over and over. Any ideas or is there any threads with the exact same warnings? I couldn't find any threads matching my warnings following a trip where everything was fine when the truck is parked and shut off only to get these warnings when restarting the truck later. Any help is deeply appreciated. 2013 F150 XLT, 3.5 Ecoboost, FX4, 191,000+ miles.

 

Start by checking that your brake fluid level is correct in the master cylinder reservoir.
While some variation in the fluid level is normal in disc brake systems due to pad wear, it should not vary more than the normal range marked on the reservoir.
If it's low, check for leaks.

Troubleshooting multiple system warnings calls for a step by step logical approach.
Randomly blasting the parts cannon is a guaranteed way to waste money and cause frustration.

All those systems rely on the brakes to be properly functional.

 

Driveway on a slope?

Yup, check your brake fluid level - do you have the ability to pull codes?

 

I checked the fluid levels and the wiring I couldn't find anything wrong. Brakes are working fine. Dew to my back and neck issues after many surgeries I can't crawl under the truck. I don't see any puddling or signs of dripping anywhere. What I did see was small tracks in the dust on the engine or signs of rats or possums. Again I didn't see any chewed wires so? I will see if I can get ahold of a tester.

 

That's unfortunate, it's not an uncommon occurrence here on the forums for people to report rodent attacks on the wiring looms, causes all sorts of slightly bizarre issues. Some of them have been down the back of the engine on the looms that go round there.

 

Mine is doing the lights, but drives perfect
