Product details

The new green J1939 Male/Female to J1939 Female/Male + OBD Angled adapter is a game-changer for heavy-duty vehicle, industrial equipment, and automotive professionals. Its distinct green housing and rugged connectors address key pain points in diagnostics, data logging, and telematics, delivering flexible, reliable access to Controller Area Network (CAN) data. Unlike fixed-standard adapters, it has a unique J1939 system: one end with male/female pins, the other with matching female/male sockets, creating a full gender-changing pass-through. A right-angle OBD-II female port complements this, solving space issues in crowded dashboards and reducing cable strain or connector damage.

At its core, the adapter acts as a gateway to the SAE J1939 network—the high-speed CAN protocol linking diesel engines, transmissions, brakes, and other electronic control units (ECUs). It forms a direct, passive bridge between the vehicle’s J1939 diagnostic port and universal OBD-II, enabling simultaneous, non-intrusive data streaming. Multiple devices can interact with the network without disrupting normal operations.

The J1939 pass-through simplifies in-line use: technicians insert it into existing diagnostic harnesses without extra couplers, cutting failure risks—vital for road-test monitoring or auxiliary system installs. The right-angle OBD port works with universal tools (scan tools, telematics dongles, emissions testers) and boosts durability by routing cables away from obstructions, lowering impact/breakage risks. The green housing allows quick identification, reducing setup time and misuse.

Internally, precision-mapped pinouts ensure flawless transmission of CAN High/CAN Low signals and stable power/ground connections, preventing data errors. Engine ECU data (engine load, fuel rate, DEF levels, trouble codes) reaches tools accurately.

Applications span industries: repair technicians use dual tools (factory software via J1939, data loggers via OBD) to find intermittent faults; fleet managers integrate OBD GPS trackers for fuel consumption and driver behavior data; R&D engineers inject simulated J1939 messages while monitoring networks; inspectors use angled OBD for emissions compliance checks.

More than a connector, this adapter bridges proprietary heavy-duty systems and universal OBD-II, boosting uptime, efficiency, and data-driven insights for transportation and industry.
