If you replace the PCM, it has to be programmed.

PCM is also the ECU. PCM is power control module whereby the transmission control are oncorporated into it whereas ECU is so called because it is only for engine control management and would have the transmission control unit separated from it.

If the second hand unit is known to be good, it can be reprogrammed to work.
