my 2003 zo6 is throwing these codes
p1571h
c1248hc
c1254hc
u1040hc
and sometimes it says t/c no communication.

Any body have any ideas why i would be getting these codes and what could be causing them.

sometimes when i turn the key on you hear a clunking noise ( sounds like its coming from abs ) then the abs and traction light comes on and i get these codes

As I recall, you've had quite a bit of work done to your car (including a new rear). Why not check with your tuner/installer as to what he thinks might be the cause. At least, that's where I'd start. :yeadog:

cAnt find these 2 codes
c1248hc
c1254hc
also if i start the car for the 1st time there is no problem. drive it for a while then shut it off and start it again you feel the brake pedal vibrate then the dic will say service vehicle, if you go in the dic for codes it will say tcs no comm or give you those 2 codes i cant find, i'm thinking i have a loose wire

found my problem, the ABS module is taking a shit.If anyone else has the same problem your module is going , the worst it gets the more codes you will get and it will happen more often.
