Detailed specifications are listed in the table below:
|
Component Name |
Interface Type |
Core Functions |
Product Advantages |
|
Vehicle Main Connection Port |
Green Type2 9Pin Male Connector (with fixing flange base) |
Matches the original diagnostic socket of new North American heavy trucks, accurately collects and transmits J1939 CAN bus data covering engine, transmission, exhaust aftertreatment, ABS braking and other full-vehicle systems. |
Equipped with flange locking structure to prevent loose connection during vehicle vibration; thick integrated injection-molded housing delivers dustproof, waterproof and oil-resistant performance; tail corrugated protection avoids wire fracture from repeated bending. |
|
Monitoring Split Port |
Green 9Pin Female Extension Port |
Adopts straight-through lossless split design, enabling long-term stable connection with fleet GPS trackers, ELD loggers and urea monitoring modules to ensure 24/7 continuous operation of vehicle monitoring systems. |
Precise pin alignment realizes zero signal loss; original Deutsch female connector ensures tight plug-in connection, effectively avoiding poor contact and virtual connection failures. |
|
Diagnostic Expansion Port |
16Pin Standard OBD2 Male Plug (J1962 Compliant) |
Compatible with mainstream automotive diagnostic scanners, emission inspection devices and portable fault readers on the market, supporting real-time reading of vehicle fault codes, dynamic data streams and emission parameters. |
Universal industry-standard plug-and-play interface requires no extra debugging, compatible with over 99% of civilian OBD detection equipment with outstanding universal adaptability. |
|
Y-Split Assembly |
Integrated Injection-Molded Split Housing |
Optimizes dual-channel wiring layout, evenly disperses tensile stress and reinforces the overall wire structure to prevent fracture at the split junction. |
Hard plastic one-piece molding features excellent shock resistance, tensile strength and distortion resistance, perfectly adapting to bumpy and harsh driving environments of heavy trucks. |
|
Main Transmission Wire |
Automotive Oil-Resistant Shielded Signal Cable |
Stably transmits CAN-H and CAN-L bus signals, guarantees synchronous operation of dual devices and eliminates electromagnetic interference and data interruption risks. |
High-purity oxygen-free copper core with full-range shielding layer resists electromagnetic interference; featuring high and low temperature resistance, corrosion resistance and oil resistance, it adapts to extreme under-hood operating conditions. |
|
Port Protection Structure |
Corrugated Elastic Buffer Sleeve |
Fully wraps the wire roots of all connectors to relieve mechanical damage caused by frequent plugging, pulling and repeated bending. |
Made of high-elastic wear-resistant PVC material, it resists cracking and peeling under long-term frequent use, greatly extending the overall service life of the harness. |
Core Product Advantages
1 .Dual-Channel Synchronous Operation, Eliminates Frequent Interface Switching
After being connected to the original vehicle diagnostic port, the harness supports parallel operation of vehicle monitoring and fault diagnosis systems. The 9Pin female port can be permanently connected with ELD loggers and GPS monitoring terminals to collect full-time vehicle operation data and meet fleet compliance supervision standards. The expanded OBD port allows on-demand diagnostic detection and maintenance without dismantling existing vehicle monitoring equipment, significantly boosting overall repair and inspection efficiency.
2. Lossless Bus Distribution, Stable & Accurate Dual-Channel Communication
Fully compliant with official SAE J1939 pin arrangement standards, the internal straight-through wiring design achieves zero signal attenuation. Dual connected devices can synchronously acquire full-vehicle CAN bus data without communication disconnection, packet loss or data delay. It delivers highly accurate and consistent detection results, perfectly matching high-precision automotive maintenance and diagnosis scenarios.
3.Dedicated Type2 New-Gen Specification, Extensive Vehicle Compatibility
Custom engineered for upgraded North American diesel heavy trucks launched after 2015, this harness is fully compatible with mainstream models including Freightliner, Kenworth, International, Volvo and Western Star. It also applies to Cummins-powered passenger coaches, construction excavators and agricultural tractors. Distinct from legacy red Type1 interfaces, this single multi-functional harness covers diverse vehicle and equipment types, effectively reducing inventory pressure and procurement costs for repair shops.
4. Industrial-Grade Automotive Craftsmanship, Harsh Environment Adaptability
Equipped with genuine Deutsch industrial circular connectors, the harness integrates dustproof, waterproof, oil-proof and anti-vibration properties, capable of withstanding mud contamination, oil erosion and drastic temperature changes in heavy truck chassis environments. Reinforced buffer protection at all connector key positions offsets damage from long-term driving vibration and manual bending, offering far superior durability than ordinary civilian wiring harnesses.
5. Universal Expansion Port, Lower Equipment Investment Costs
There is no need to purchase expensive professional heavy-duty truck diagnostic hosts. Ordinary commercial 16Pin OBD scanners and official emission inspection equipment are fully compatible with this harness. It enables small and medium-sized repair shops and inspection stations to complete full-range detection and maintenance of new North American heavy trucks without additional investment in professional equipment, achieving outstanding cost performance.
Application Scenarios
- Compliance Management for Freight Fleets: One branch connects ELD electronic loggers to collect speed, mileage and engine load data to meet freight supervision regulations; the other OBD branch links diagnostic scanners for vehicle fault troubleshooting during maintenance.
- Fault Repair for Auto Shops: No need to disconnect fleet GPS monitoring devices; directly plug diagnostic tools into OBD port to read & clear engine fault codes, monitor real-time data of urea aftertreatment, transmission and ABS systems.
- Vehicle Annual Emission Inspection: Connect emission testing equipment via OBD port to rapidly read diesel vehicle OBD compliance emission data without interrupting normal operation of original on-board monitoring devices.
- Maintenance for Construction & Agricultural Machinery: For Cummins-powered excavators, loaders and tractors, support real-time equipment condition monitoring and simultaneous fault diagnosis.
Compatible Vehicle Models
New heavy-duty trucks: Freightliner, Kenworth, International, Volvo, Western Star;
Large passenger buses, construction machinery and agricultural tractors equipped with Cummins engines.
Interface Distinction & Usage Tips
- Old & New Interface Differentiation: Green 9Pin = Type2 (Post-2015 New Heavy-Duty Trucks); Red 9Pin = Type1 (Pre-2015 Older Models). Two versions have different pin definitions and cannot be used interchangeably.
- Operation Steps: Insert green 9Pin male plug into vehicle factory diagnostic port; connect fleet GPS/ELD devices to 9Pin female port permanently; plug diagnostic scanner or inspection equipment into OBD male port as needed.
- Communication Troubleshooting: Confirm all plugs are fully seated, and verify your vehicle is post-2015 model with Type2 green 9Pin port.
- Storage & Maintenance: Coil the cable gently after use, avoid sharp bending at connector roots to extend cable service life.
