Diagnostic systems are like a doctor for your vehicle
For the past couple of decades, carmakers have equipped vehicles with on-board diagnostic systems that help to determine, or even predict, the condition of certain auto components. The purpose behind on-board diagnostics is to alert drivers about existing or impending mechanical failures that need to be addressed in order for the vehicle to remain operational. Drivers can then either use the information to make repairs or adjustments independently or to bring the vehicle to a mechanic or dealership for needed maintenance. Mechanics can refer to diagnostic codes generated by the on-board system as a reliable guide for correcting issues, which can save the car owner a significant amount of time and money that would otherwise be wasted on a guessing approach to troubleshooting.
On-board diagnostics have evolved immensely since being first introduced in the 1980s, when alerts consisted merely of a warning light generated by the diagnostic system. In some cases, an internal problem had already happened and preventive measures were too late to employ. Today's on-board diagnostics provide much more detailed reports that identify specific issues that need to be addressed. Not only does self-diagnosis prevent today's cars from breaking down, it also helps measure vehicle emissions to determine the vehicle is meeting mandatory standards as established by the Environmental Protection Agency. Should a diagnostic system detect that emission levels are violating federal regulations, the driver is alerted so action can be taken to correct the levels.
