so then theres abs sensors on the rear wheels, i thought the one in the pumkin was the only one

 

No, you only have the one sensor on the diff in the back.

If I may be so bold as to speak for him for a moment... I think Weed was trying to tell you to check the wire itself. Take a look at the wire from the sensor up to the CAB in the engine compartment behind the battery.

 

ok so i check the wires, everything looks good, so i went ahead and replaced the output transmission speed sensor also. well no luck the problem is still there. so now im completely fustrated on what it could be. also i have a 9.25 rear that came factory with 3.55 gears. i dont know if this info would help me out some more. but as for now theres new sensors in there and the problem is still there

 

oh also i have a superchip 3865 and have it tuned to towing performance. but i never changed the tire size. i dont kow if this info would help also

 

hey guys i still need help

 

Did you do brakes within the time the light came on? Could it be possible the system needs to blead? Go to autozone and have them read the code and come back with that specific info. Were guessing untill we know!

 

i did my front brakes back in January. i havent done the rears yet, i belive theres still the original with 100k on them...as far as bleeding, i dont know how to do that. i did go the advanced to get codes, but nothing pops up on the code reader, so this is where i am stumped. but ive replaced every abs and speed sensor. i was told to re do my rear axle fluid again, but i dont know. i really need some help.

 

JDG, when you said "everything looks good", what did you mean? How did you check the wires? Did you check the resistance of the sensor & wires from the CAB connector in the engine compartment? Mine read about 1.6 Kohms for the rear sensor.

 

In my ecpertise. Light means code, throwing parts at the problem is costing money. If your not willing to pay the guy with tje tools, then you need the tool. The tool is 2500it dollars. Wich would you rather pay for! Go get the code from Autozone. Your guessing untill you have it.

 

I didnt check the resistance... I followed the wires and tested with a test light...i just spoke to the stealership and told them its almost been a month and the prob still exaist so i told them they have 2 options either refund me my money or run a proper diagnostic for free..so they chose the free one but now i wanna see if i can find the prob before it goes to them
