Lights up like a Christmas tree 02/18/22

Can any of y'all help me with this:
This only happens if I'm driving pretty heavy on the freeway, and it shuts down when I get into normal street traffic.

Any Ideas, other than contact dealer?? It's got a 6" Lift, 35's, Magnuson Supercharger, 5.29 gears...

 

Wheel speed sensor?

 

Wow, lot of variables there! Could be something simple, but then again!

 

Maybe sensor wire stretched...

 

Has your front collision sensor been re-calibrated for your 6” lift? My wager is that is your problem.

 

Happy Frihigh Day

 

Yea, Friday post alright. You deserve your truck having problems. "Look how cool I am snappin' photos with my phone as I drive 85+ MPH!"

 

That was my initial thought, but would the front sensor being off throw errors for ABS and BSM too?

 

Not sure, I know that it’s the front sensor or a wheel speed sensor because of a bad wheel or axle bearing.

 

IIRC, I had similar lights on the dash when my TSS sensor on the front of the truck was absolutely caked in slush/ice after a long highway drive?

 

The PCS and BSM sensors are acting up because there is an issue with your ABS, so don't be too worried about those.

 

Wife took the pics while I drove...

 

No it hasn't.... Is that a "dealer only" thing???

 

I've had that happen when I lived in Colorado

 

Looks like you are in warranty, so off to the dealer. Other than that, run an OBD scanner on it to see where the fault originated from before taking anything apart. Start with a purpose in mind, not like a blind squirrel searching for his nuts. If you don't have a scanner you can usually borrow one from an auto parts store.

 

I have a scanner, I use torque, and it will say "no faults found"...

 

Looks like a malfunction but I can't be sure. He was going down a grade, 2,500Ks, making not quite 90 miles an hour. His sensors broke in to a stream...He said "Baby" get a photo of this dash. ...reminds me of Cash.

Mine did that when the steering angle sensor was out of adjustment after my lift. Your dealership won’t cover it as the lift caused the issue but I think it was only $60 to get it calibrated. No issues after the fact.

 

Define "driving pretty heavy on the freeway" Like are you going fast, or swerving in and out of lanes, jumping ditches?
