What are the features of OBD2 To Green Right Angle Type2 J1939 Cable
Structural characteristics
One end is a 16 pin plug that complies with the OBD2 standard, used to connect the vehicle's OBD2 diagnostic interface. This is a standard interface that most modern cars are equipped with, making it easy to connect with external diagnostic devices.
The other end is the green right angle type 2 J1939 interface, typically a 9-pin structure, which has specific electrical characteristics and physical shapes for communication with devices that support the J1939 protocol. The design of the green right angle helps to better adapt to spatial layout during installation and use, avoiding excessive bending or compression of cables.
function
Protocol conversion: OBD2 is mainly used for fault diagnosis and basic information reading of automobiles, while J1939 is a widely used communication protocol in commercial vehicles and some industrial vehicles, used for complex data exchange and communication between various electronic control units (ECUs) of vehicles. This cable can achieve the conversion between OBD2 protocol and J1939 protocol, allowing devices that support OBD2 (such as General Motors diagnostic instruments) to communicate with vehicle ECUs that use J1939 protocol, thereby expanding the application scope of diagnostic equipment and facilitating fault diagnosis, parameter setting, and performance monitoring of vehicles using J1939 protocol.
Data transmission: It can transmit data obtained from the vehicle OBD2 interface, such as engine speed, vehicle speed, fault codes, etc., to devices with J1939 interface, such as professional commercial vehicle diagnostic instruments, onboard computers, etc. At the same time, it can also transmit instructions or configuration information sent by J1939 devices to the vehicle's OBD2 system, achieving bidirectional data transmission and interaction.
