    Features of Ancel 3400 Truck Scanner

    Here are some exceptional features of the Ancel 3400 Truck Scanner that make it worth your hefty investment:


    To begin with, the Ancel 3400 Scanner hardware comes with a Quad-Core ARM Cortex-A7 CPU. In comparison with Cortex A8, this unit has a smaller size and straightforward mechanism. It even consumes lesser energy.

    Moving forward, you will get a flash drive with 8GB storage for seamlessly running the scanner's operating system and software. 1GB RAM complements it well, promoting the smooth functioning of this diagnostic tool.

    The best part? Using the tool's cable, you can easily connect the scanner to your truck's engine from an OBD2 port. This lets you diagnose underlying issues with your vehicle's engine timely before they become a nuisance.

    If we talk about this diagnostic tool's exteriors, you'd be impressed with its durability as provided by high-quality plastic. No matter how many times you use it in a day, it's meant to last for years without any wear and tear.

    Lastly, the ergonomic grips on either side of the device make it one of the user-friendly picks. With these, it's easier to hold this heavy truck scanner without fearing dropping it down as you work.

    I have a request for information due to the lack of information provided in the poorly prepared HD3400 User Manual.

    1. What engines or trucks require the use of the ‘Cat 9-pin’ connector. It appears to be the same pin configuration of the J1939 plug. On page 7 & 8, it discusses the non-OBD-II interface plugs, but provides absolutely no information as to what plugs are used on what vehicles or engines.

    2. How do you determine or know when to use the J1939, 9-pin plug compared to the ‘Cat 9’ 9-pin plug?

    It would be extremely helpful to know where more specific, detailed information can be found for my HD3400 Scanner, serial number RD34-2402-3620-0131.

    Thank you, and look forward to your timely reply.
