Electric Power Steering (Fault Codes)
B210D-00 The power supply is too low
B210F-00 Input circuit 30 has a malfunction
U0101-00 Communication with control unit transmission has a malfunction
Anyone got ideas about these codes showing up with intermittent steering malfunction issue.
Has anyone come across this and if so what is the solution ?

You electric steering rack is requesting attention.
The rack module is very sensitive to poor conditions.
Actually there may not be anything wrong with the rack itself but only poor environment conditions causing rack to act up. Namely
CAN-Bus signal
Floating GND
low power supply
Check chassis voltage while faults are active. Battery, Alternator or GND may have gone marginal.

Your faults show a marginal PWR/GND connection.
Have you driven in heavy rain or standing water ??
