OBD2 to Open End Cable: An Important Tool for Automotive Diagnosis

In the field of automotive electronic diagnostics, the OBD2 to open end cable, with its unique design and strong compatibility, has become the core tool for connecting in vehicle diagnostic systems with diverse equipment. This cable uses a standard 16 pin OBD2 interface at one end, which is compatible with various diagnostic ports for passenger and commercial vehicles; The other end is designed as an open end or a customizable pin interface, which can flexibly connect devices such as oscilloscopes, logic analyzers, and custom diagnostic modules, providing highly open diagnostic solutions for technicians.

Technical Features: Balance between Standardization and Customization

The OBD2 interface strictly follows the SAE J1962 standard and achieves power supply, CAN bus communication, and K-line protocol transmission through specific pins. The open end design breaks through the limitations of traditional diagnostic equipment, and users can choose welding, crimping, or plug-in terminals according to their needs.

Application scenarios: From maintenance workshops to intelligent networking

In traditional maintenance scenarios, this cable can be connected to multi brand diagnostic instruments to quickly read fault codes from systems such as powertrain (P code) and chassis (C code). In the field of new energy vehicles, its compatibility advantage is more prominent - it can simultaneously connect battery management systems (BMS) and motor controllers (MCU) to achieve insulation monitoring and thermal management strategy verification of high-voltage systems.

With the development of the Internet of Vehicles, this cable is becoming a key component for remote diagnosis. By integrating 4G/5G modules through the open end, vehicle data can be uploaded in real-time to the cloud diagnostic platform, and automated fault analysis can be achieved through the use of tools.
