Which devices can use J1939 to OBD2 cables?

Here are some devices that can use J1939 to OBD2 cables:

Diagnostic instrument: General automotive diagnostic instruments usually follow the OBD2 protocol, while electronic control units (ECUs) in trucks often use the J1939 protocol. By using J1939 to OBD2 cable, the universal diagnostic instrument can be connected to the truck ECU to achieve functions such as fault diagnosis, reading and clearing fault codes, and monitoring vehicle operating parameters.

Data collector: In fleet management and vehicle performance research, data collectors are used to collect various operational data of trucks. By using J1939 to OBD2 cable, the ECU data of the truck based on J1939 protocol can be converted into OBD2 format, which is received and recorded by the data collector for subsequent analysis.

Car computer: Some car computers need to communicate with the vehicle's ECU to obtain vehicle status information, achieve functions such as real-time display of vehicle operating parameters, navigation, and integration of vehicle information. By using J1939 to OBD2 cable, the onboard computer with OBD2 interface can be smoothly connected to the truck ECU with J1939 protocol.

Remote monitoring terminal: In order to achieve remote monitoring of trucks, the remote monitoring terminal needs to exchange data with the vehicle ECU. The J1939 to OBD2 cable can transmit data from the truck ECU to a remote monitoring terminal, which then sends the data to a remote server or monitoring center through a wireless communication network.

Aftermarket modification equipment: such as some aftermarket devices such as intelligent fuel consumption monitoring systems and engine performance optimization devices, in order to obtain accurate vehicle operating data and communicate with the vehicle ECU, J1939 to OBD2 cables are also used to connect with the truck ECU.
