A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
Some Honda engine computers are equipped with LEDs that light up in a specific pattern to indicate the DTC. General Motors, some 1989–1995 Ford vehicles (DCL), and some 1989–1995 Toyota/Lexus vehicles have a live sensor data stream available; however, many other OBD-I equipped vehicles do not.
The Chrysler 300 continues a tradition of full-sized, front-engine, rear-wheel drive, V8-powered luxury sedans the company has offered, starting in the 1940s with the Chrysler Saratoga and Chrysler New Yorker, followed by the Chrysler Windsor, Chrysler Newport, and the Chrysler Cordoba, with the last rear wheel drive sedan, the Chrysler Fifth Avenue that ended production in 1989.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
The CAN bus protocol has been used on the Shimano DI2 electronic gear shift system for road bicycles since 2009, and is also used by the Ansmann and BionX systems in their direct drive motor. The CAN bus is also used as a fieldbus in general automation environments, primarily due to the low cost of some CAN controllers and processors.
A modern vehicle can have more than 70 ECUs that use CAN FD to exchange information over the CAN bus when the engine is running or when the vehicle is moving. On a CAN bus, a frame is the basic unit of messaging. For a classic CAN bus, a frame consists of an 11-bit identifier along with an 8-byte message payload.
The 3.3 has a timing chain, and is an interference engine meaning that the valves will collide with the pistons in the event of a timing chain failure. Vehicles using the 3.3 include: 1990–1993 Dodge Dynasty, Chrysler New Yorker, Chrysler Imperial, (replaced the 3.0 L Mitsubishi 6G72 engine) 1990–2010 Chrysler minivans
Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world.
