A working machine management system includes a working machine having a prime mover and a control unit and a key device which is detachable from the working machine and is used for operating the working machine. The key device stores first authentication information for identifying a drivable working machine and second authentication information necessary for the prime mover to continuously operate. When the key device is attached to the working machine, the control unit confirms validity of the key device based on the first authentication information, compares input information from the outside with the second authentication information to determine whether the prime mover can be operated if the key device is valid, and controls operation of the prime mover according to the determination result.

A vehicle is shown such as a snowmobile, where a frame includes a tunnel and a front frame portion comprised of cast halves. A suspension system is comprised of upper and lower control arms connected to the front frame portion. Some of the frame components are adhesively fixed together. A powertrain is supported by the frame, and is comprised of an engine and a clutch. The clutch includes a clutch guard supporting an oil container. The engine has an exhaust system which extends through the front frame portion. The snowmobile also has a rear snow deflector.

A vehicle is disclosed which includes a controller having at least one of a vehicle security module and a playback module. The vehicle security module may operate in a secure once mode of operation or in a secure all mode of operation. The playback module records ride information associated with the vehicle. The ride information may be provided to an external device.

A vehicle control system includes: a vehicle start control unit that when a predetermined start prohibition condition for the vehicle is established, prohibits the vehicle from starting; and a notice control unit that before the vehicle is prohibited from starting by the vehicle start control unit, provides a first advance notice that is an advance notice of prohibiting the vehicle from starting, into a cabin of the vehicle.

A system and method for preventing unauthorized modification to engine control software or an engine control system of, for example, a refrigerated transport application is provided. Particularly, the embodiments described herein prevent unauthorized parties from inadvertently or intentionally making changes to the engine control software used for controlling the engine or the engine control system that could, for example, potentially bypass emission strategies implemented in the refrigerated transport application. Accordingly, emission strategies such as, for example, EPA Tier IV not-to-exceed (NTE) regulations can be maintained.
