Lots of error lights after first 4WD use

[Demeeder]

Took the ‘21 PW to the beach for the first time and used 4WD for the first time. Not long into the drive, I got the following warning lights sticking around:

ESC fault
Adaptive Cruise Control fault
Service forward collision
Lane sense and auto high beam unavailable

Was a light drive, nothing obnoxious. Maybe a few puddles.

Appreciate any thoughts you have.

Sounds like dirt on a front sensor

Thanks...that's what I thought/hoped. Sprayed the front of the truck clean prior to posting and about 20 minutes into the drive back the faults went away.

This happens to me on long trails sometimes. I think it's because the traction control (plus other things) keep kicking on and off when you are off road. This causes the truck to think somethings wrong. All the faults will go away the next time you cycle your truck on/off. Turning the traction control off when you start the trail seems to help, but I haven't tested this thoroughly.

Not all trails do this to my truck, but there are some that do it more than others.

I have not been off roading in mine yet but this kind of sucks to know what I might be seeing on a week long trip in the mountains. Most of the trails we run are 3-5 hours long each. It will be frustrating to keep getting alarms and not knowing if something is really wrong or not.

I am sure it was just one of the front sensors getting obscured. I have not had any issues after this occurrence.

The ESC fault is odd. The others do sound like a sensor issue. The ESC disables itself in 4 low anyway.

There is a specific code and message when the front sensor needs to be wiped. Your Christmas tree of lights is not from that.
