So what year is OBD II compliance required in my car? It’s actually easier to diagnose problems with an obdII vehicle than a pre-obdII one. In a stock car, obdII can easily identify problems with just a sniffer inserted in the exhaust pipe. In fact, the obdII standard required pre-obdII cars to conform by 1996. Some older vehicles have had trouble with obdII, especially hondas.
GM’s early roll-out of OBD II allowed GM to test the system in the field
In order to meet the requirements of the California Air Resources Board, all new vehicles must have basic on-board diagnostics capability (usually referred to as “OBD-I”). In 1991, California enacted a law requiring all vehicles to have some level of on-board diagnostics, but the name was not applied until OBD-II was introduced. Unlike today’s standards, however, there were no standardized diagnostic connectors and standardized test signals. The Society of Automotive Engineers recommended a common diagnostic connector and protocol for all new vehicles in the United States. The new system became mandatory in 1996.
The OBD-II standard defines a standardized hardware interface that connects vehicles to diagnostic devices. The connector is a 16-pin, two-wire, female J1962 connector, and must be mounted within two feet of the steering wheel. This distance also ensures safety. The system can detect a range of vehicle problems, including engine malfunctions and faulty transmissions.
OBD II requires minimal additional hardware. The new software in the on-board computer will replace the existing one. GM was able to test the system in the field by rolling out new vehicles in 1996 and 2001. The new system will increase the retail cost of vehicles by $61, according to the federal government’s 1996 estimates. While a small increase in the cost of a new car, the new OBD II system is expected to ultimately reduce the cost for the consumer.
In addition to the early roll-out, OBD-II is now used in many states in place of tailpipe testing. OBD-II stores trouble codes in the vehicle’s on-board computer and helps the testing technician verify compliance with emission standards. In addition, supplementary vehicle instrumentation is installed in the vehicles alongside the manufacturer’s instrumentation for drivers to view during normal operations. Scanners can also be used for active fault diagnosis and tuning.
Early roll-out of OBD II allowed a quick testing of the system before it was widely adopted by manufacturers. GM also received a boost from testing the system in the field. Early roll-out of OBD II also allowed GM to test the system and ensure its functionality. This system is a great way to protect vehicle owners from car trouble.
The system has several uses, such as tracking mileage and informing OnStar of an accident. It also lets drivers know when the airbags in their vehicles have gone off. OnStar can also send emergency services to help them with an emergency. The OBD-II system allows the car’s GPS system to send a signal to an OnStar call center.
GM’s early roll-out of OBD II allowed GM to launch its full OBD II compliance
The GM Class 2 serial bus was designed to meet the federal emissions standards for OBD II. It contained all the required diagnostics and communications features. The system was designed to send out state-of-health messages, regardless of whether or not the vehicle had a problem. GM has successfully implemented all 10 mandatory OBDII modes with its new technology.
The OBD standard began in the late 1980s, when the California Air Resources Board (CARB) required vehicles to have basic on-board diagnostics (OBD I). Although it wasn’t called OBD until 1996, automakers had until then to comply with the protocol. The data link connector and diagnostic trouble codes are not standardized, but the Society of Automotive Engineers (SAE) recommends a standardized connector.
GM’s early roll-out of the OBD II standard allowed the company to launch its full OBD II compliance program. While the OBD standards are mandatory for light-duty vehicles and trucks, the HDOBD specification is made mandatory for heavy-duty engines and certain types of passenger cars by the end of 2010.
The LT1 Corvette has a partial OBD II system. This system stores OBD II codes but does not turn on the MIL and runs on OBD I diagnostics. This early roll-out of OBD II allowed GM to launch its full OBD II compliance program without major problems. And the early roll-out of OBD II allowed GM to launch its full OBDII compliance program with little to no glitches.
OBD II information is commonly used for Pay-As-You-Drive insurance and vehicle telematics. Some vehicles are equipped with the CAN protocol to handle the data that the cars generate. The CAN protocol is not fully compliant with U.S. OBD II standards until 2003, but it does meet the requirements for cars and light trucks. CAN signaling protocol is the same in all U.S. cars.
The GM H-body cars had the hybrid system. This allowed GM to launch its full OBD II compliance program before the other major car manufacturers. Some of the cars that were equipped with the hybrid system included the Buick Regal, the Chevrolet Lumina (’95 only), the Pontiac Grand Prix, the Cadillac Seville, and the Oldsmobile Cutlass Supreme.
OBD II is a universal standard for vehicle diagnostics. It’s a system within the vehicle’s on-board computers that allows the owner to check on the car’s health. This information can help mechanics diagnose problems before they turn into major issues. This technology allows mechanics to easily access this information. However, many consumers are still reluctant to use it.

OBD2 is an electronic diagnostic tool that communicates with the car’s computer through a serial bus called the GM Class 2 standard. It is compatible with all GM vehicles and has been certified to meet federal emission requirements. The GM Class 2 module reports the state of the car every few seconds, regardless of other messages on the bus. This data is used by car telematics devices and Pay-As-You-Drive insurance.
