Noticing the stark differences between the two versions of onboard diagnostic scan can in most cases be quite a challenge because the whole difference in some cases may not exist after all. This is the main reason why most people in a bid to buy the latest version of OBD 2 may end up acquiring a scan tool with the features only found in OBD 1.
The shift in technology has necessitated developments in the auto industry with tools which are likely able to work and give results commensurate to the technology itself. With more demand for the OBD scan tools, more improvements are brought forth.
OBD2 is simply a replica of OBD 1, with only noted difference in terms of coding scope. Some of the notable differences may come as;
- The installation– the old diagnostic tool referred to as OBD 1 was initially installed under the vehicle dashboard. In contrast, the new generation OBD 2 is usually installed within the drivers compartment where reaching it cannot be a challenge.
- Engine check– in the diverse cases at a glance, the use of OBD 2 is synonymous with the term check engine light. This feature alone has the capacity to go directly into the areas of fault and at times even help with its eventual correction. It has the capacity of therefore putting the user away from the eventual risks posed. In contrast, the OBD 1 scan tool had no capacity to pinpoint , it only read the codes,
- Reliability– the replacement of OBD 1 with the new version was necessitated by the need for the user to access relevant information useful for the healthy use of the car. It is in this respect that the OBD 1 could not meet the diverse need for the information. OBD 2 provides the information and even more.
- Engine performance– knowing how your vehicle engine performs is heavenly. While the old OBD could provide certain technology based aspects to do with the car engine. The OBD 2 has been seen to be the Alfa and the Omega when it comes to getting information that pertains to the engine efficiency.
- Formation-while it is known that most OBD 2 Scan tools are software based formations which work on particular range of supported protocols, their ability to provide quick data rests on the embedded chip. To conform to the times, the chip is reprogrammed or updated but is neither replaceable nor removable. It is this place that all the relevant data is stored. The option of replacing the chip in OBD 1 made them weak to give information or as data storages.
- Fast– OBD scan tool devices can be expected to give the most relevant and fast data that a mechanic can use in correcting the trouble codes. The system puts it above the old generation model which had very limited capacity to give fast data. The data covered by the OBD 2 is also not comparable to the OBD 1.
- Software specifications– the OBD 2 has come with the most relevant software suited for the 21st The specifications on most of their software makes them easy to install and used. Moreover, the software within the OBD 2 category is in most cases open source. The OBD 1 was hard to find in terms of the software and even the physical tool itself.
- User satisfaction– using the OBD1 was hard. In most cases, they were manufacture based tools which could only be accessed from the specific car manufactures. Not any more, the engineering society recommended the manufacture of universal OBD 2 scan tools which could be used across the board. This helps cuts on the overall cost of purchasing the tools.
These and many more other factors clearly spell the diverse difference. OBD 2 has been changing its face with the advent of even better ones like the several wireless and Bluetooth versions. The use of OBD 1 among the beginners in the area of OBD scan tool use is still widespread.
