check to see if each ID motor operates normally.
Make this checking in the presence and absence of a load.
Confirmation Tasks
Check for any incomplete insertion or skew insertion of the
SSNS connector of the PU PCB and the SSNS connector of the

After checking the connections, turn on the power again, and
see if the error is issued again.
