Side loads on an Electronic Steering Column Lock (ESCL) can prevent the ESCL from releasing upon command. An Electric Power-Assisted Steering (EPAS) system is used to reduce or eliminate any side load on the ESCL to mitigate this problem. The EPAS system is activated in response to driver authentication before the driver requests a transition to a ready-to-drive state. The ready-to-drive state is entered only if the ESCL is unlocked. If a predetermined time elapses between driver authentication and the request to enter ready-to-drive state, the EPAS is deactivated and the ESCL is commanded to re-lock.
