I ended up having to pull a 30000 pd roll-off truck up a fairly steep hill today. We just got some snow and ice and he couldn't make it up the hill. My truck seemed to pull it just fine (he was under power, too) but when I got almost all of the way up the hill, the brake and ABS lites came on. Checked parking brake- not engaged. It kept pulling with no apparent signs of trouble. After I was done I turned the truck off. The lites went off after starting and running the truck for about 5 minutes. Anyone have any Ideas why the lites came on?

 

Eaither a connector got wet or it got confused with wheel spinning,braking etc.If dosen't reoccure would not worry about it.Low brake fliud on a steep hill also.check fliud level.

 

mine came on on my 03. i wasn't towing a load when it came on, just driving down the road unloaded.

anyway... turned out to be some sort of speed sensor that the dealer replaced in about 30 mins.

if your's doesn't come on again i wouldn't worry about it too much. but if it does it shouldn't be any big deal. the only thing that the service manager said is you're ABS won't work while the light is on.

Did you happen to get alot of snow packed in the wheels, I have heard of that messing with the ABS sensors. jm02

 

wheel spin will make the lights come on... try playing in the snow [drifting, donuts...] and the light will come on after a good bit of wheel spin. just tap the service brakes and it will clear the light....
