ANCEL HD200 Bluetooth Heavy Duty Truck Scanner, Speed Limit and Idle Reset for Cummins & Caterpillar Engines, J1939/J1708 Diesel Code Reader & All-System Diagnostic Tool, Lifetime Free Updates

Works well great help to my business

Not at all helpful. Claimed it would do this and that. Once you get into it. It does nothing that it said it would.

This worked great,tracked down the problem then cleared the codes!

Does not change the speed on a vehicle

It provides lots of information

Didn't work like it's supposed to. Couldn't even read the truck information correctly and you couldn't erase codes, read them properly, and or change the speed limits. Took over a month to get a refund back. I would not buy this.

Great product thanks

It does great at reading codes. Do not buy it if you have a Detroit and are looking to run dpf regen or wanting to adjust idle settings. It does not work for either of those.

Some cord was clear and some not

À date il lit les code et les efface j’ai pas essayé de faire une regen encore , et j’ai un Cummins X15 date de production 06/2021

ANCEL HD200 Bluetooth Heavy Duty Truck Scanner Full System Diesel Scanner Diagnostic Tool Speed Limit Reset for Cummins and Caterpillar Engine Diesel HDOBD & OBD2 Code Reader for Diesel Trucks & Cars. I could only test this on OBD2 at this time. I was able to use it, but only with the app from the company. The device would not work with my existing OBD2 analyzer apps even though those apps use every other OBD2 dongles I have tried them with. Once connected to the new app, it was able to read all my engine info just fine. However, I am not as familiar with the app, so I wasn't as comfortable with it. I suspect anyone using this for the heavy engine diagnostics will have a better experience, since it appears to be geared towards those engines.

This heavy duty truck scanner uses a compact Bluetooth dongle for quick, roadside diagnostics without bulky gear. It supports speed limit adjustments on Cummins and Caterpillar engines and helps catch small problems early. This tool reads and clears codes across engine, ABS, and transmission systems for full diagnostic coverage. It adjusts max speed settings to match local laws, improving safety and helping avoid insurance penalties. This scanner includes lifetime free software updates, avoiding subscription fees and saving money long-term. It connects in 2 seconds via Bluetooth and shows real-time data faster than most check engine lights. The system is simple to use with an easy main menu and portable design that works well in emergencies. It works with most truck brands and uses OBD and J1939 links, built tough for harsh driving conditions. I think this is unique. I haven't seen other bluetooth HD truck scanners. Cool :)

At first glance, this would seem like a very simple scanner. It does not have a big tablet screen, or thick cables running all around. It does not come with a thick book of instructions, to tell you how to sue it. In fact, it looks like many of the those smaller scanners for cars, but just larger. Does it perform the same way? Heck, no! This scanner is astounding! Here's why... First, you download the Ancel Trucker app to your phone. Zero fees involved - nice! You then simply plug the unit into an OBD2 port on your car or smaller truck - or the Green 9-pin on your full-sized unit - and let the two connect. That's about it. It's that simple. The amount of information is amazing. Not only can you pull up just about any codes your on-board computer module reads, but you can also ask for "live information". And you can select different live information to be layered over top of other information. Think of this as a handheld diagnostic computer scanner, in a very streamlined package. As simple as the unit looks, it also appears built for the road. It has a very tough exterior, and although I would not use it to drive nails with, it does seem tough and well built. You can read virtually any code your vechicle can throw. You can modify a number of parameters. For example, you can change idle characteristics. You can circumvent speed settings that the truck has built in. And you can clear codes. A library function allows you to look up code meanings. This does not replace a good mechanic, but it does allow you to begin to isolate a problem area, and then determine if it is something you feel confident enough to look into, or take the truck in. There are no extras with the purchase of this unit. Ancel states that up-dates will be offered at no charge, and there will not be hidden fees, charges or ads embedded into the app. The Bluetooth worked without a fault! There was no issue at any time - it just worked! Bottom Line - For less than the cost of two hours of shop charges, you can purchase a tool that will help you gain insight into how your vechicle is doing, and it will perform like that for years to come. Ancel should be commended for making such a comprehensive tool, and keeping it updated at no cost to the consumer! Even if you are not the trucks owner, this simple and small device could save your trip by letting you know a new thrown code is not going to harm the truck, if you keep going. A really excellent device!
