For automatic transmission vehicles without keyless entry functions, there is a flaw in the design of the circuit of the integration control unit (ICU) that controls the key interlock mechanism (this mechanism is to stop the ignition key being pulled out unless the AT shift lever is in the 'P' position), and therefore, when the ignition key is turned off, the circuit may be affected by an induced electromotive force from the fuel pump, and this may result in a delay in the action time of the key interlock solenoid. If this occurs, it becomes possible to pull out the key, even when the AT shift lever is not in the 'P' position, as long as the pulling action is quick. If such an action is taken while the parking brake is not engaged, the parked vehicle may start to move.
