Hello all I've fitted my abs ecu which was a pain but doable the problem I have now is my traction control light sometimes comes on and when it does my car struggles to start and the idle is all over the place I've cleaned and replaced ICV Which has helped a little but the problem still persists I've done the paperclip test and it's got no faults the code it back with are 12 and 31 so as I've said before any help would be good Ta

Was it the right ABS ECU for the car?  Did the ident codes match?

It's the same one that was on my car I just got it fixed at BBa reman so I'm stumped I thought it might be crank angle sensor but don't see how that will put traction control on unless it's a coincidence and it just needs a tech 2 to accept Tc and something else has gone at same time ??

They might be completely un-connected. Try a paperclip test and see if there are any codes (see below in my sig. for instructions.).

I've done paperclip test and it shows up 12 and 31 I'm gonna get proper tech 2 on it later in week to see if there's anything else jimbob did mention in the maintenance guide that you sometimes have too tech 2 it too accept Tc but again I don't see how that can affect starting up I've also tried my idle control valve on my mates elite and it worked fine so its not that
