Hello, replaced the left door sliding motor and door-opening control unit located on the driver's side floor the door does not work.

I tried connecting the right motor line to the replaced motor, to see if the motor worked, and the motor runs even if I have to manually open the door to slide it.

In door opening control unit diagnosis no error.

I tried to diagnose the bsi but it won't let me go into diagnostics.

Do you have any suggestions .

Thank you
