OBD II Automotive Diagnostic Code Readers
61Automotive code readers of today are a step up compared to their original counterparts. In a nutshell, automotive code readers also known as auto scanners or OBD (on-board diagnostic) scanners are electronic hand held devices that can be hooked up to an ODB port to diagnose and identify technical issues that are affecting a particular vehicle.
Every vehicle manufactured after 1996 has an OBD port found below its dashboard. These types of vehicles are broadly classified as OBD II compliant vehicles and prior to 1996, there wasn’t a uniform diagnostics system for vehicles and each diagnostics system utilized by a particular vehicle is typically unique to its manufacturers. It was after 1996 that the OBD II system was introduced and that every vehicle manufacturer had to comply with a uniform OBD system that allows universal automotive code scanners to diagnose and identify engine problems. Indeed the primary difference between the OBD I and II is the conception of a universal system for engine diagnostics.
The ability to use automotive diagnostic code readers made it possible to dramatically simplify the process of diagnosing and repairing engine related issues through the application of a uniform OBD system which an automotive diagnostic code reader to pull off the same trouble codes regardless of the OBD II compliant vehicle’s model and manufacturer.
After hooking up the reader on your vehicle’s OBD system, the electronic device would provide you with real time data regarding your vehicle’s specifications and engine condition. All this information will typically be available on the reader’s LCD screen. The reader may also have added capabilities to assess the activation of the CEL (check engine light) and provide other information pertaining to the fuel and sensor system. One other thing that makes the automotive diagnostic reader so useful is the fact that most of them can assess your vehicle’s engine emission and tell you if it complies with mandated smog emission standards.
Automotive diagnostic code readers and automotive repair manuals have proven themselves extremely useful for car owners and your average do it yourself mechanics. The readers can give you a clear insight on what areas of the engine are affected by a technical issue and which components need to be repaired or replaced. This saves you the cost of making unnecessary replacements for parts that aren’t even affected by the trouble at all. It also saves you from the possibility of causing further damage to your vehicle through your efforts of manually diagnosing the vehicle just to see what is actually wrong. If you decide to turn your car in to be repaired in automotive repair shops and handled by certified technicians, the insight that the automotive code reader has given you would allow you to effectively negotiate repair cost. It would prove extremely useful in deterring dishonest mechanics from cashing in on you since you know exactly what is wrong with the vehicle or at least an idea regarding what components are affected.
Even automotive mechanics use these handy devices to perform an accurate diagnosis on a vehicle before conducting any repairs. In fact, it’s typically the first tool that they ever use when doing their work. In the same way, this saves them the trouble of manually diagnosing a vehicle which was the case prior to the conception of a universal OBD system,obdii code reader and automotive readers in particular. The automotive code reader allows them to accurately identify the issue, make the repairs in the shortest amount of time and avoid potential damages by tinkering on unaffected areas of the vehicle’s system.
