2001 T4R Evap leak was original culprit in my no pass smog dilemma.
Then the rr break slave cylinder went. We fixed it put on new breaks bled and its been a game of clue since. The ABS and break lights stayed on. We finally installed new/ used ecm for the ABS and it worked! All the lights went off and my odometer and spedometer came alive. I put the OBD2 on it and all sorts of codes came up but no check engine light or ABS light. Do I need to reset or reprogram the new brain? I asked before and was told it was basically a plug and play scenario. So close to getting legal, what do I do now?
The codes that came up as the evap circle flashed: C0205 wheel sensor
C1254 current pressure switch malfunction
C1223. " in ABS control system
C1207. " " in P/R range switch
C0278. " " current open or short circuit in ABS solenoid relay circuit
Which is what I started looking for.

So close. Any help is welcome. I am daunted again.
P.S. what's a tag?

Thanks
Carol
