• Accurate Protocol Matching, Stable Communication Without Packet Loss

Strictly follows official SAE J1939 pinout definition with precise mapping of CAN-H and CAN-L signals. No delay or disconnection occurs when reading fault codes, real-time data streams and vehicle operating information, delivering accurate and reliable detection results.

• Dedicated for New North American Heavy Trucks with Wide Compatibility

The green Type2 9Pin connector is exclusively built for post-2015 North American trucks, compatible with mainstream heavy-duty models including Freightliner, Kenworth, International, Volvo and Western Star. It also works for buses, excavators and tractors powered by Cummins engines. One cable fits multiple vehicle models to cut inventory costs for repair shops.

• Industrial-Grade Automotive Durability

The round connector features dustproof, waterproof and shockproof performance, suitable for chassis environments full of oil, mud and extreme temperatures. Corrugated buffer sleeves at both connector roots prevent internal wire breakage after long-term plugging and bending, extending service life.

• Lightweight Short Cable for Easy Portability

Short cable design avoids tangling during storage, offering flexible operation for cab installation, chassis inspection and bench diagnosis. No external power supply needed; communication activates immediately after connection for simple operation.

• Dual-Purpose for Repair & Fleet Management

It supports fault diagnosis and ECU data viewing for repair garages, as well as connection with ELD loggers and GPS trackers to collect vehicle speed, mileage and engine load data, meeting regulatory compliance requirements for freight fleets.

1. Auto Repair Shop Troubleshooting: Read & clear engine fault codes, monitor real-time data of SCR aftertreatment, transmission and ABS systems;
2. Freight Fleet Management: Connect with ELD electronic loggers and vehicle GPS to collect driving data such as speed, mileage and engine load to comply with freight supervision regulations;
3. Vehicle Annual Emission Inspection: Link with emission testing equipment to read OBD emission data of diesel vehicles for annual inspection;
4. Construction & Agricultural Machinery Maintenance: Daily fault diagnosis and operating condition inspection for Cummins-powered excavators, loaders and farm tractors.

New heavy-duty trucks: Freightliner, Kenworth, International, Volvo, Western Star; Large passenger buses, construction machinery and agricultural tractors equipped with Cummins engines.

1. Interface Differentiation: Green 9Pin = Type 2 (Post-2015 New Heavy-Duty Trucks); Black 9Pin = Type 1 (Pre-2015 Older Models). The two versions have different pin definitions and cannot be used interchangeably.
2. Operation Steps: Plug the green 9Pin connector into the vehicle's factory diagnostic port, then connect the OBD female end to your scanner or tracking device; power on the equipment to read vehicle data automatically.
3. Communication Troubleshooting: Ensure the plug is fully seated and confirm your vehicle is a post-2015 model equipped with the green Type2 port.
4. Storage & Maintenance: Coil the cable gently after use, avoid sharp bending at connector roots to extend cable lifespan.
