After some 4 wheeling in HL and low my ABS & TT4 lights stay on. Yes i tried taking in and out of gear several times before returning to the pavement.While driving around town the truck makes on occasion a loud clunking while making turns and the truck comes to a halt.Feels like a wheel or two is locking up. Truck will not move until i come to a complete stop.
Has anybody had similar problems or solutions.
Thanks

Yes. The same thing happened last week after an off road Hummer Happening in Englishtown, New Jersey. I have an '01 H1. Muddy track. The ABS and TT4 light will not go out. I have also had the same problem with what appears to be wheel/brake lock up upon a start. Will disengage when I stop. Have a call into the dealer but no response yet. Are you still having your problem?

 

It has taken a back seat for now. The truck left me stranded in the mountains. It just died.Engine will crank but wont run. Currently have a error code P0380.
Hopefully its something minor that i have overlooked as opposed to having to replace the injector pump. I did look at the brakes and they need to be replaced. Maybe they are binding which inturn is tripping the TT4 thinking the apposing wheel is losing traction.Just a guess.Keep me informed as to what you find out. Good Luck!
