EPS uses an electric motor to provide directional contol to the driver. EPS CM has a charging circuit to supply current to a motor temoporarily.
EPS CM sets this code and turns on warning lamp if charged voltage is too low due to a abnormal charging circuit. At that time EPS CM inhibits it's own function.
