Abstract
A method for preventing a vehicle controller from being hacked includes allowing the vehicle controller to transition from a lock state to an unlock state as a security access with a vehicle diagnostic device is completed, transmitting, by the vehicle controller, a session holding time to the vehicle diagnostic device in the unlock state, monitoring, by the vehicle controller, whether a request message is received from the vehicle diagnostic device every session holding time, and determining, by the vehicle controller, whether to transition from the unlock state to the lock state based on whether the request message is received.
