The invention relates to the vehicle electric control technical field, and specifically relates to an electronic steering column lock control system and method; the electronic steering column lock control system comprises the following elements: a main controller used for connecting/disconnecting a ground line of an electronic steering column lock, sending an unlock/lock enable signal to the electronic steering column lock, and receiving a lock state signal returned by the electronic steering column lock; a backup controller used for receiving a main controller order and controlling the connection/disconnection of a power supply of the electronic steering column lock; the electronic steering column lock receiving a control order of the main controller so as to unlock/lock, and returning the lock state signal to the main controller. The control system uses two control units to respectively control an anode and cathode of the electronic steering column lock, thus greatly reducing lock function abnormity conditions caused by controller failure. A hard-line Limphome handshake signal is added between the two control units for authentication, thus effectively preventing mal-locking fault caused by abnormity of the single control unit.
