hello everyone I have a 04 monte carlo ss supercharged now I have the abs/traction control off light on and it says service traction system , I replaced both front hubs still have lights I then replaced both back hubs still have problem I unbloted the abs pump ground wire and cleaned the connection still have problem , I traced wires of traction control and inspected them , besides being filled with dry dirt when I opened plactic wire covering the wires look ok I got a reading of around 4.5 to 4,8 ohms of resistance from testing wire ( is that good ?) I did have 4 codes on abs c1248DRP disabled ,c1225frt excessive left wheel speed senor variation c1232 open or short frt left ,c1233 open or short frt right speed circuit I cleared them and still have 3 only one that is gone is c1225 all the others are still there please help I am at a loss to what it could be

 

It's the speed sensor in the hub bearing that triggers the lights. You have to change the harness.
