2001 ford powerstroke 4x4
i installed painless tc lock up module that was defective. i am getting trouble codes p0603 and p1000 and my torque converter is not locking up by itself.
i removed module and put wiring back to normal. (factory) Torque converter will lock up if you ground out the solenoid wire. i am wondering did the module burn up my pcm? What could i check to fix my problem with torque converter?

i have a superchips flashpac installed. and it has never had any trouble with codes or with the operation of the truck until installed painless module.
