Last week I had a Fosgate amp and sub installed. Then I went directly to the tire shop and had some wheels put on. When they got done, the ABS/check brakes lights came on and it dings 13 times. It comes on every time i get in the truck now.

It isn't throwing a code ( I checked it with my PPE and went down to Brakemasters and they checked too) and the brakes feel fine. I had Brakemasters do a visual and they couldn't see anything wrong.

Has anyone had this issue or have any suggestions?

My 04 has done that a few times. Not in quite a while though. I read somewhere it usually only happened if you started the truck with your foot on the brakes. I think there may have been a TSB about an update to get it fixed.

did they sever or disconnect the abs sensor?
