I am getting trac off,anti lock and service stability system come on all at once.Had codes read and got
c1225 left front wheel speed signal
c1232 left front wheel speed sensor erratic
c1241 magnasteer circuit malfunction
c1245 low tire pressure (dash readout says tire pressure normal)
Last year i had both front wheel speed sensors changed
Also the battery died awhile back and replaced that
Where to start? Any info would be greatly appreciated

Start with the left front hub. The wheel speed sensors in some hubs fail rather quickly. I'd recommend Timken for the replacement. The C1245 is likely a history code, if the dash indicates normal.

Plus 1 on the Timken hub assy!

Archon thanks for the reply.Took it back to garage today were hubs were done.The work was still under warranty.They said the left sensor wire was rubbing up against the axle.Trac is working correctly now and not getting trac off,anti lock or service stability lights anymore.What a relief.I cant recheck the codes at the moment thou because i also had p0171 and after they fixed the sensor problem they ran seafoam through the engine and reset the check engine light to see if that may fix the po171 problem.If all the codes above are fixed all i should have left is
po171 and p1811
