About OBD2 Scanners Built Into Vehicles

On-board diagnostic computers is a technological automotive terminology referring to the on-board reporting and self-diagnosing capability of a vehicle. OBD, short for on-board computer system, was first introduced in the US market during the late 1970s. These days, nearly all vehicles in the world to come with built-in OBD2 system. However, there are still a few vehicles that require special installation of OBD2 diagnostic computer.


An obd2 scanner is an instrument used for the detection of vehicle malfunctions. It uses digital signal processing to generate a detailed picture of the troubleshooting process. The OBD2 scanner can be built-in in a vehicle’s engine management system (EMSI) or can be installed as a device that needs to be connected to an OBD2 reader through a connector, like those used with a handheld computer. A handheld obd2 reader is used to read the data from the obd2 scanner.

There are three basic reasons to have an obd2 scanner. The most important reason for having an obd2 scanner is to determine the problem or malfunction of your vehicle. The second reason is to debug trouble codes that are generated by the vehicle software. The third and final reason is to perform preventive maintenance on your vehicle. In this article, I will show you practical intro on how to operate or set up your obd2 connector or portable OBD reader.

Most cars today, especially the old vehicles, come with built-in OBD diagnostics systems. The OBD is actually a hardware device or a set of software that helps the mechanics to diagnose the problem of a certain vehicle. In most cars, you will find two kinds of OBD – the built-in and the portable. The built-in OBD uses the internal scan tool of the car whereas the portable OBD comes with a specific port for a particular scanner. It can be used in both manual and automatic cars.

The portable OBD2 scanner can be used on almost all types of vehicles, since it has the capability of reading most scanners. You can buy it directly from the market without the need of a technician. It is however important to be familiar with the vehicles specifications to know what the right product is for you. Some vehicles require a high intensity LED (or light emitting diode) scanners, while others only require the OBD2 modem.

The portable OBD2 scanners are less expensive than the built-in units. Some of the portable scanners are built with a barcode scanner built-in. This feature allows it to scan any kind of sensor. It is convenient for use even by people who have no technical knowledge. You should also check whether these scanners work on cars having the Microsoft Windows operating systems.
