P0743, 53, 63 all circuit A in TCU Mercedes-Benz -

Question

I cannot get these codes to reset after replacing conductor plate and electrical plug. Tested all 12v solenoids, cleaned and reinstalled. Still won't move and can't clear codes. Tried the Autocom CDP+ 2014 OBD Scanner w/no success

Answer 1

P0715 Supply voltage for RPM sensor

P0743 Torque convertor clutch circuit electrica'

P0753 1/2 4/5 shift valve

P0763 3/4 solenoid valve

If the conductor plate was replaced, and reinstalled, you would need to reset the CK ENG LT and you would need to reset the adaptation for the transmission

 Whenever the conductor place is replaced, or the solenoid is replaced for a MBZ, the code has to be cleared, and the transmission adaptation has to be reset, You would need a factory level scan tool
