The Adapter Cable converts a 6-pin J1708 diagnostic connector, commonly found in older commercial vehicles, to a standard 16-pin OBD2 (J1962) connector. This product enables connecting modern OBD2 diagnostic equipment to vehicles using the J1708 communication standard. The cable is specifically designed to provide a stable and reliable data connection between the vehicle and the reading device.
Thanks to its construction, this Adapter is suitable for use in demanding environments such as workshops and garages. The cable supports the communication protocols transmitted via the J1708 port, including J1587. This allows technicians to read diagnostic trouble codes (DTC's), view live data, and analyze other system parameters of the engine and electronic control units (ECU's) on compatible trucks, buses, and industrial machines.
Application and functionality:
The cable serves as a physical bridge between two different types of diagnostic connectors, extending compatibility between older vehicle systems and modern scanners.
- Connectivity: Connects a 6-pin J1708 port of the vehicle to a 16-pin OBD2 port of a diagnostic device.
- Diagnosis: Enables reading engine data, sensor data, and fault codes on vehicles using the J1708/J1587 protocol.
- Compatibility: Designed for heavy commercial vehicles, such as trucks and buses, that are not equipped with a standard OBD2 or J1939 port.
Compatible vehicles and applications:
This Adapter Cable is designed for a wide range of heavy and commercial vehicles equipped with a 6-pin J1708 diagnostic port. This includes various trucks, buses, and other work vehicles, mainly from North American and certain European manufacturers from around 1995 to the mid-2000s.
Compatible brands include, among others:
- Caterpillar
- Cummins
- Detroit Diesel
- Freightliner
- International
- Kenworth
- Mack
- Peterbilt
- Volvo Trucks
- Western Star
Important: Before purchasing the product, always check your vehicle's connection. This may vary by model, engine, and year of manufacture.
