When you open the hood of a car, you might be puzzled by various plugs and cables. One of the key components is OBD, OBD2, and EOBD, which stand for On-Board Diagnostics systems.In this blog post, we will disscuss this difference.
OBD ,which full nume is On-board diagnosic,is an early version of the car diagnostic system,applicable to cars manufactured between 1980 and 1995.OBD uses a 16-pin standard data interface,primarily used for detecting engine issues, emission system problems, and faults in other components.
The OBD2 port is an upgraded OBD standardized connector that is widely used in cars manufactured after 1996. Through the OBD2 interface, OBD2 scanners such as Autel MX808S,MK808BT Pro,MP808BT Pro are connected to identify problems and fault codes of automotive components such as the engine.
OBD2 is not only a standardized connector port, but also a standardized communication protocol. For use in vehicles, it is designed to provide faster data transfer and improved diagnostic capabilities through professional diagnostic scanners such as Autel Ultra and updated versions with the standard CAN protocol.
EOBD is the European version of OBD2, extensively applied in the European market. EOBD terms needs to comply with European emission standards and has higher requirements in terms of data transmission rate and detection speed. It is primarily applicable to the automotive market in Europe.
OBD and OBD2 are both American standard interfaces and protocols. Their main differences are as follows:
Unlike the American standard OBD and OBD II, EOBD is dedicated to the European version of OBD II. The system is mainly applicable to all cars and diesel vehicles made after 2001 and 2003 respectively.
|Suitable vehicle||Cars manafactured between 1980 and 1995||Cars manafactured after 1996||after 2001 all gasoline vehicle and after 2003 diesel vehicle|
|Application||Californian standard||Federal standard||European standard|
1.First you need to purchase an Autel diagnostic tool, such as Autel MX808S scan tool;
2.Next, insert the Autel MX808S diagnostic scanner into the OBD2 interface;
3.Then click Diagnosis and select Read DTCs in the Autel Maxicheck MX808S interface.
4.Finally you can see the error code diagnosed by Autel professional MX808S scanner.
Autel covers OBD2 diagnostic scanners from entry-level to advanced, which establishes contact with the vehicle through the OBD2 or EOBD interface, reads the vehicle's DTCs, and processes them.
Here are some popular Autel diagnostic scanner recommendations:
OBD and OBD2 feature 16-pin universal communication interfaces, while EOBD may utilize either 16-pin or 18-pin interfaces. These protocols comply with North American or European standards and facilitate automotive diagnostics. Professional OBD2 scanners such as Autel MK808BT Pro and MP808BT Pro can be connected to vehicles via these interfaces to retrieve freeze frames and real-time data, aiding car owners in diagnosing DTCs.
