  • Vehicle immobilizer system for electronic engine control
    Patent number: 6181026
    Abstract: An engine immobilizer has an armed state in which it disables an engine and a disarmed state in which it does not disable the engine. The immobilizer disarms when an authorized security code is received from a transponder during an attempt to start the engine. The controller for the engine immobilizer monitors engine-running sensors and switches to the armed state if the engine-running sensors indicate that the engine is not running even though the ignition switch has not been detected to have been put in the off position.
