Since 1996, all domestic vehicles have been equipped with an on board diagnostics port (OBDII) brought about due to the Clean Air Act Of 1970. To meet these standards, manufacturers turned to electronically controlled fuel feed and ignition systems. Sensors measured engine performance and adjusted the systems to provide minimum pollution. These sensors were also accessed to provide early diagnostic assistance. In 1988, the Society of Automotive Engineers (SAE) set a standard connector plug and set of diagnostic test signals. The EPA adapted most of their standards from the SAE on-board diagnostic programs and recommendations. OBD-II is an expanded set of standards and practices developed by SAE and adopted by the EPA and CARB (California Air Resources Board) for implementation by January 1, 1996.
The earliest versions of the on board diagnostic systems provided a simplistic “idiot” lighting system warning the driver of general engine trouble. However, the advent of the microprocessors of the 1980’s and 1990’s changed everything. Modern OBDII connectivity provides more than 100 system parameters providing precise diagnostics and efficiencies. These efficiencies provide a wealth of information not only to the service center but to companies that provide ancillary services.
GPS Tracking Users Benefiting From Driving Behavior Monitoring
GPS Tracking has become a valuable resource to consumers and business owners alike. The ability to understand the whereabouts of family members such as new teenage drivers or elderly parents provides peace of mind. For businesses, knowing when vehicles and employees arrive and depart job sites as well as monitoring driving behavior saves both time and money. These GPS tracking manufacturers are capturing information provided by the OBD port and incorporating it into a true resource manager. The OBD compatible tracking device not only transmits continuous ten (10) second positioning updates, but also provides mileage, ignition on/off status, VIN number, engine idling, harsh breaking, rapid acceleration, low fuel, etc. All of these features provide fleet tracking managers as well as concerned consumers a better understanding of their vehicles and operators.
