This versatile OBD2 to J1939/6-Pin Y-cable serves as a universal bridge for heavy-duty vehicle diagnostics. It takes a single 16-pin OBD2 male connection and splits it into two specific round connectors: a green 9-pin (J1939) and a grey 6-pin (J1708). This allows you to switch between older and newer trucks or connect two devices simultaneously without changing cables.
Accurate Specifications & Features
- Connectors: 1x Standard 16-Pin OBD2 Male connector (Black) + 1x Green 9-Pin J1939 Male connector + 1x Grey 6-Pin J1708 Male connector.
- Protocol Support: Fully wired to support both J1939 (CAN bus) and J1708 (serial) communication protocols.
- Material Quality: Industrial-grade waterproof Deutsch connectors with red internal seals and locking rings, paired with high-quality flexible PVC wire.
- Durability: Built with pure copper wire cores for stable data transmission and heavy-duty outer jackets that resist oil, heat, and vibration in truck environments.
- Plug & Play: No hardwiring required; simply connect the OBD2 end to your scanner, then choose the 9-pin or 6-pin end and plug it into the truck's port.
Compatibility & Application
- Vehicle Fitment: Universally compatible with heavy-duty trucks, buses, and commercial vehicles (Freightliner, International, Peterbilt, Volvo, Mack, etc.) using the 9-pin or 6-pin diagnostic port.
- Tool Compatibility: Works perfectly with OBD2 diagnostic scanners, laptops with truck software (Cummins Insite, Detroit DDDL, Allison DOC), and ELD compliance devices.
- Functionality: Enables reading fault codes, live data monitoring, ECU programming, and fleet tracking on both modern (9-pin) and older (6-pin) truck systems.
