P0900 Clutch actuator circuit error, TCM repair, Toyota Yaris, Corola, Citroen C1, Peugeot 107, MMT 

The car was brought with P0900 error, another service replaced clutch actuator with a new one, no luck! The car was not moving and the N was flashing in dash, whatever gear you'll select. You can't rev up the engine. The TCM (TRANSMISSION CONTROL MODULE) is located under the dash, above steering wheel column (on LHD vehicles). After you remove the top of dashboard, you have to unscrew 4 screws and disconnect the three connectors. After you remove the transmission control module you have to measure the MOSFETs and replace the bad one(s). After repair was done, reinstall the transmission control module and test that the repair was successful before you put the dashboard in place.
