Abstract: The CAN based vehicle immobilizer is a vehicle immobilizer which utilizing the CAN bus of the engine (powertrain) CAN connection on the OBDII/J1962 port or the vehicle CAN system, will completely immobilize a vehicle, preventing use of said vehicle and the starting of said vehicle engine. The vehicle immobilizer system can be installed by a 3rd party on an aftermarket basis and used to immobilize a vehicle despite an immobilization system being already present on said vehicle is not accessible by said 3rd party. The vehicle immobilizer system enables a user to immobilize the vehicle engine efficiently without shorting the CAN network bus lines, and with a minimum of modifications to the vehicle. The vehicle immobilizer system enables a user to immobilize a vehicle from starting the engine and from being driven with minimal modifications to vehicle wiring and with limited to no changes to the vehicle electrical system.
