mine is because of the smaller tires up front..
I think I figured it out tho, and it didnt throw the code since I have cleared it..
did the regearing formula..
tricked the computer into thinking I have 3.31 gears

my abs and brake light just came on after I installed my 4.10s. When I get my retune to fix the speedo will this prob go away? How did you trick the computer 01Thunder?

Ok I see now its a networking code. Most likley related to your intermittent ABS light. Most network codes are BS and to sensitive. All modules are polled every 30 sec, If they dont talk back they through a code. Most common during programing. I suspect the ABSMD triped once your light came on even though it was not on at the time you read the codes. Ignore the Network code and focus on Finding your ABS fault and you should be good.
