Servo Restart Failed

Error ID: 2201, 2211
The pump motor in the module was unable to move into the correct position
for restarting.
When the module is switched on, the first step is to switch on the C phase of
the variable reluctance motor. The rotor should move to one of the C positions.
The C position is required for the servo to be able to take control of the phase
sequencing with the commutator. If the rotor is unable to move, or if the C
position cannot be reached, the error message is generated.
