abs problem HELP
Ok so my abs light is on speedo doesnt work and i replaced the rear vss sensor. The truck is throwing a p0500 code in the abs system and a p0603 code on the ecm side. I kno the p0500 is a wheel speed sensor or abs module problem. Anyway to pinpoint what side is the issue? Any help would be great.

I also changed out the ABS sensor on the rear diff as the plug had been damged at some point.

Ill check all the lines but the wires seem to be fine. Ive been running 35s for aboug 9 months now and havent had a problem. The light always stays on now and will go out if i hit a bump just right

When I installed my levelling kit and tires the abs light was intermittent (like yours went on and off with bumps and wet conditions). I just left it for about 2 years and it seldom came on... however one day after driving for a few hours the light came on, kicked off my cruise control and the speedometer jumped a bit. This was when I looked at the rear diff sensor. Someone on the forum was having an issue with "engine stumble" at maintained highway speed similar to mine and suggested the fix... It worked for the abs light and speedo problem but my stumble was an IPR.
ABS light hasn't come on in awhile but it will once winter gets here.

I think you need an AE to read ABS codes or take to the dealer. Both my SCT and my Insight will not retrieve ABS codes. You may be able to ohm test the sensors but I don't know for sure.... Bismic, M-Chan, Cheezit or Benny will know about that one.
