EPS uses an electric motor to provide directional contol to the driver. EPS CM cuts off a motor relay to protect EPS from abnormal operation if a system has an error.
EPS CM checks a motor relay condition by testing. EPS CM sets this code and turns on warning lamp if a motor relay can't be cut off in abnormal condition.
