FAQ
How does this splitter cable help fleets reduce operational costs?
By simultaneously monitoring engine performance (J1708) and vehicle operational data (J1939) through a single connection, it reduces diagnostic time by ~60%, while predictive maintenance lowers unexpected downtime costs by ~30%.
Can I customize the cable length, color, or logo?
Yes, fully OEM customizable: adjustable AWG 16–24, length 0.5–8m, and brand/logo options.
Is this cable shielded against electrical interference?
Yes, triple-layer EMI shielding ensures stable, zero-loss dual data stream even during engine start.
Does dual data stream collection affect diagnostic accuracy?
Patented signal separation technology allows each protocol independent processing channels, ensuring both data streams operate without interference and improving diagnostic accuracy by ~15% compared to single-protocol mode.
How is the connector design optimized for heavy-duty trucks?
Military-grade connectors with gold-plated pins, shock-proof locking, and protocol-specific layout ensure compatibility and durability.
How many times is the product quality checked during manufacturing?
Each cable undergoes four-dimensional quality verification: conductivity, shielding, protocol compatibility, and environmental durability.
Is this cable durable for heavy-duty truck diagnostics?
Yes, full-plastic housing and high-grade pins provide long-term stability for professional fleet environments.
Does it support OEM diagnostic scanners and telematics tools?
Fully compatible with professional diagnostic and telematics devices.
What unique advantages does dual data stream collection offer compared to traditional single-protocol diagnostics?
Captures correlations between engine control units and vehicle management systems, identifying relationships between fuel efficiency degradation and driving behaviors – insights impossible with single-protocol diagnostics.

Q: What’s the main advantage of a dual data stream cable?
A: The key advantage is diagnostic efficiency. Instead of connecting to the OBD2 port and then the J1939 port, you can do both at once. This is crucial for fleet managers and technicians who need to correlate data from both networks quickly, such as comparing engine parameters (J1939) with vehicle speed (OBD2).
