Characteristics and functions of right angle OBD2 male to J1939 female cable

The right angle OBD2 male to J1939 female cable is a special cable used for automotive diagnosis and data transmission. The following is its related information:

Structural characteristics

Interface type: One end is a right angled OBD2 male connector, which facilitates the connection of the vehicle's OBD2 interface in some limited space areas, reducing the occupation of surrounding space, and can more flexibly adapt to different installation positions and angles. The other end is a J1939 female connector, used to connect with devices with J1939 interfaces, such as engine control units and onboard diagnostic systems for heavy-duty trucks.

Internal cable: The cable contains multiple wires that are responsible for transmitting different signals, such as power signals, data signals, etc., to achieve communication and data interaction between the OBD2 interface and J1939 devices. In order to ensure the stability and anti-interference of signal transmission, cables usually adopt shielding measures, such as adding shielding layers.

function

Protocol conversion: OBD2 is a standard protocol for on-board diagnostic systems used in light vehicles, while J1939 is a commonly used communication protocol for commercial vehicles and non road mobile machinery. This cable can achieve the conversion between these two protocols, allowing diagnostic devices or tools based on OBD2 interface to communicate with vehicles or devices using J1939 protocol, expanding the application scope of the equipment.

Data transmission: It can transmit data obtained from the vehicle electronic control unit (ECU) through the OBD2 interface, such as fault codes and vehicle operating parameters (such as vehicle speed, RPM, water temperature, etc.), to devices with J1939 interface for analysis and processing. At the same time, commands or configuration information sent by J1939 devices can also be transmitted to the vehicle's OBD2 system to achieve control or adjustment of certain functions of the vehicle.
