OBD1 needs corded connection while OBD2 can be connected hands freely via Bluetooth or wifi. Thus, OBD2 provide better and more standardized vehicle protocols and system checks data. In like manner, OBD2 is an advanced technology improved from OBD1. In this article, we will explain in details the difference between OBD1 and OBD2 scanners. Later more standardized and vehicle’s information was developed in OBD1 and OBD2 respectively. In its early phase, the development of OBD system was mainly to turn on the malfunction light in cars. OBD is onboard diagnostic, a process to scan vehicle with an onboard computer. But, what is the main difference between OBD1 and OBD2 scanners? There are two main types of OBD scanners on the market: OBD1 and OBD2 scanners. In fact, mechanics, too, use these devices to diagnose car problems. Without them, you won’t know what’s wrong with your car. OBD scanners are devices that let you read and diagnose error codes your car displays.
