My 2015 F150 instrument cluster started going haywire, displaying multiple warnings including “Hill Start Assist Not Available”, “Service AdvanceTrac”, the ABS light was on, parking sensors were disabled, etc. This is a rather common problem on Ford vehicles and can be caused by a few things. The U0415 code means Invalid data was received from the anti-lock brake system (ABS) control module. Causes are varied including wiring faults, a bad wheel speed sensor(s), rarely a defective ABS control module/ABS pump and even more rarely the PCM itself is the cause. In my case, the problem was a rubbed through wire going to the front left wheel speed sensor. Additionally, a bad throttle body can cause similar issues but you will usually have a “WRENCH” icon displaying as well and the vehicle will be in a limp mode.
