OBD stands for "on-board diagnostics" and the II refers to the second set of universal standards agreed to by all motor manufacturers. It is the on-board automotive diagnostics system that has been required by the USA’s Environmental Protection Agency on every new motor vehicle sold in the USA since 1996. EU countries and many Asian countries have also now made it a requirement that new model cars be OBD II compatible.

OBD, or On Board Diagnostics, is a system used on automobiles to monitor some components and to detect malfunction. If some component is not functioning properly, information about the system is stored in an on-board computer so it can be recovered later by the service technician. OBD-II is the second and the most current version of this technology.

OBD stands for On-Board Diagnostics and this is the second generation of this technology. Starting in 1996, all vehicles sold in the United States were required to include this technology. It requires a computer on board the vehicle that monitors the engine and power train systems and logs any problems that could cause the vehicle's emissions to increase. A failed OBD-II test means that there is a problem with the vehicle.

OBD stands for "on-board diagnos?tics," a computer-based system built into all model year (MY) 1996 and newer light-duty cars and trucks. OBD monitors the performance of some of the engines' major compo?nents, including individual emis?sion controls. The system provides owners with an early warning of malfunctions by way of a dashboard "Check Engine" light (also known as a Malfunction Indicator Light or MIL, for short).

On-Board Diagnostic systems (OBD) on 1996 and newer vehicles will be checked as part of Delaware’s vehicle inspection program. OBD technology benefits motorists, repair technicians and our environment. It’s good for motorists because it monitors the vehicles performance every time it is driven and identifies problems immediately allowing service to be done before more serious problems develop.

The OBD II offers a buffer that will keep you or us from damaging your vehicle. The OBD II is used strictly to retrieve and diagnose your vehicles information and is not designed to tamper with or change anything outside of its domain. The only thing that the OBD II can modify on your vehicle is the check engine light and the error codes associated with that function.

OBD-1 is in reference to Title 13 California Code 1968 titled "Malfunction and Diagnostic System for 1988 and Subsequent Model Year Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles with three-way Catalyst Systems and Feedback Control." filed on 11-15-85. This required cars sold in California to have an on-board computer processor for on-board self diagnostics of computer sensed emission related components, fuel metering device and EGR (exhaust gas recirculation system).

All cars built since January 1, 1996 have OBD-II systems. Manufacturers started incorporating OBD-II in various models as early as 1994. Some early OBD-II cars were not 100% compliant. There are three basic OBD-II protocols in use, each with minor variations on the communication pattern between the on-board diagnostic computer and the scanner console or tool.

Pre-OBD-II cars had connectors in various positions under the dashboard and under the hood. All OBD-II cars have a connector located in the passenger compartment easily accessible from the driver's seat. Check under the dash or behind or near the ashtray. A cable is plugged into the OBD-II J1962 connector and connected to AutoTap or another scan tool. AutoTap is available in PC/laptop or a Palm PDA versions.

In some ways they are do have an advantage, they are small and robust and are totally standalone, they cover all three protocols ( ISO,PWM and VPW ). However they do not have the same capability as software based systems and are specifically aimed at fault diagnosis, DTC retrieval etc ( see our shop for a more detailed description).

While you should evaluate eligibility for the H-1, the TN better serves most Canadians. H-1 permits also require specific bachelor's degrees and tight relationships between the degree and the job. See the H-1 page for exceptional "work experience substitute for degree" rules. Look at this graphic to see if your profession fits within the O-1, TN and/or the H-1B. Use this flowchart to decide between the TN and the H-1B.

Don't use Microsoft PPTP. Again, this attack is against Microsoft PPTP, not PPTP in general. PPTP allows all sorts of encryption and authentication schemes; Microsoft just invented some really lousy ones. Even better, if you are a VPN user, use IPSec. This is a much more robust protocol.

OBD stands for On Board Diagnostic. There are 2 versions. OBD-I and OBD-II. In 1970 Congress passed the Clean Air Act and established the Environmental Protection Agency (EPA). This started a series of graduated emission standards and requirements for maintenance of vehicles for extended periods of time. To meet these standards, manufacturers turned to electronically controlled fuel feed and ignition systems.

Yes, you can order a partial kit of the essential parts, and construct your own, though you will need some additional commonly available parts. These kits do NOT contain step-by-step instructions, and they are NOT suitable for beginners. You must have knowlege and experience with electronic circuits; know how to read schematics and troubleshoot problems with them, or you may not have good results. Back to Top

Immediately before OBDII was mandated, some manufacturers implemented it, either partially, or fully on certain selected models. Some of them went to the 16 pin connector, but all the data lines were the same older bus .... ie, only the connector changed, but was not OBDII. On some models, there actually was a partial implementation, and some were completely OBDII compatible even though they were not required by law.
