OBD2 EOBD and OBD3 are two different kinds of scanners, the former is more capable to detect specific problems associated with emission as compared to the latter.
As opposed to OBD1, OBD2 is capable of scanning for trouble spots such as fuel line obstructions, electronic signals interfering with the car’s performance, leaks and other problems that will eventually be identified as they occur.
In order to scan properly, it must also have a chip installed which enables it to read the car’s diagnostic codes. The chips can either be purchased or they can be built by a car owner himself.
OBD2 scanner is designed for cars manufactured before the year 2000 and it is possible that some older models may need to have their codes upgraded on and thus, the price tag for this service may be more expensive.
However, this kind of scanner is very efficient when it comes to discovering the source of the problem and hence, allows you to quickly put your car back on track. It also enables you to find out the car code for any car manufactured in the last two years. This is very important especially if you happen to come across a car code that matches your vehicle.
You will find various versions of OBD2 scanner. Some of them are designed specifically for vehicles that have the OBD1 facility installed in it. These are the ones that you would need in case you are having a problem with your vehicle only because of an OBD1.
A scanner like this can easily detect trouble spots like power leaks and the like. With this device, you will be able to diagnose and rectify problems regarding your car’s emission system.
OBD scanner is basically a computer that has been equipped with the ability to read data from your vehicle’s diagnostic system. By making use of the scanner, you will be able to decipher the codes or signs of trouble inside your car and print them out to your specified document.
Once you get hold of these codes, you will be able to assess what exactly is wrong with your car. For example, there could be a slight problem with your fuel system or your engine might be overheating. Once you determine what the problem is, you can fix it by installing the necessary parts.
Before buying an OBD2 scanner, you should find out how compatible it is with your car. The scanners usually come with software to make it compatible. However, you will have to check this so as to see whether you will be able to download the software from the Internet. There are some cases where you will not be able to do so. If there is no compatible software, you should buy one that will work with your specific model.
Another important thing to consider is the quality of the scanner. Look for one that is portable and is capable of scanning all the important channels. There are scanners that are only meant to work on a certain channel. In this case, you will not be able to use it in some cars as they are not supported. In addition, the OBD2 OBD reader will support the latest revisions of the technical standards for cars.
