Well I had my gears changed to 4.10's and after I had them done I started throwing ABS and BRAKE lights. The truck is tuned by wheatley and tuned RIGHT for the gear ratio and the tire size. He was puzzled with this also and even sent the tune to hp tuners and they coulden't find a problem with the file. He cant pull the codes either cause i don't have a check engine light cause the problem is in the BCM.I took the truck by the dealership just to see if they could hook it up and tell me if it was a sensor but that was a waste of time and i was told i would pay 90 bux for them to say its my tire size... Does anyone have any clue what can be done? Any and all info would help.

 

Did you try unhooking the battery and letting the truck sit for an hour or so? Also, try zip tie'ing the ABS connector plugs together incase it has a loose connection. Did this to my '09 and it solved my abs and stabilitrack lights

 

is your truck lifted

 

Battery has been done, and i can try the zip ties but we will see. The truck is dropped not lifted but has been throwing codes before the drop. Appreciat the help keep em coming

 

try cleaning the vss on the tranny. that was a prob for me before. or the sensors on the wheels. easy things to try before you spend $$...

 

dont worry. it will go away after a few weeks. mine did the same thing

 

Its been doing it for a good couple months now i think its gonna stay till whatever it is is fixed.. Its really annoyying too it it beeps 23 timesss trust me i knowwwww lol

 

Had a similar problem

According to the tech that fixed mine, BCM and Speed sensor had to be recalibrated along with the computer.

 

I know I'm not running the same truck, but I had a similar situation.. all I had to do is change the solenoids in the ECBM. I found some on line from a place in Dallas for $100.
