Spent way too much aggravating time trying to get it to work. Product does not live up to expectations and is being returned Review: The scanner comes in very handy and has deemed very useful, but you will have to really take your time to figure out this unit on your own. The instructions that come with it are very basic and does not go into much detail into all of the features and functions. For example, it does not describe what the "expert mode" is or what it does when selecting that function to clear codes verses the normal code clearing function. If you try to contact customer support, you can only do so through email and their response time is about 48 hours. In my case, the customer support team was not helpful at all in answering my questions. They actually had told me that they can not recommend a product for my engine while having the exact product for my particular engine which made the customer support seem really uneducated on their own scanners. In summary, it is a great tool that has been very helpful, but you will need to spend time learning how to use all of the functions on your own. ## Features - Designed for Cummins Ancel HD3400 heavy duty truck scanner can read/clear codes, live data, ECU, DPF regen, DPF reset, etc. for your Cummins engine: Cummins X12/x15/ISX15/L9/B6.7/Westport L9N/ISB/ISD/ISL/ISG/ISX/ISF/ISBe/QSM11/ISM/QSX15/ISC/ISN/ISK, such as Freightliner, Peterbilt, Kenworth, International, Ford Pick-up F650/F750, Chevy Pick-up, RAM Pick-up, Volvo Truck, Mack, Western Star, Autocar, Ford F600/F700, Terex TR50, Bluebird, Bobcat, Komatsu, Zoomlion, ect. - Designed for Detroit HD3400 heavy duty truck scan tool can work for your Detroit DD13/DD15/DD16, Series 50/60, MBE 900/MBE 4000, OM501/OM 502, DDDL 6/DDDL 7, Freightliner Cascadia M2/108SD/114SD/122SD, Western Star 4700/4800/4900/6900/47X, Kenworth C500, ect. - Designed for Paccar The diesel scan tool is compatible with your Paccar engine: Paccar PX-7/PX-9, MX-11/MX-13, such as Kenworth T780/K270E/K370E/T680 Next Gen/T680/T880/W990/T180/T280/T380/T480, Peterbilt 579/389/567/367/365/548/535/536/537/220, ect. ️Please note that for PACCAR engines that need to do dpf function after 2017, HD3400 truck diesel scanner also need another crossover adapter to be compatible. - Designed for Caterpillar HD3400 diesel scanner diagnostic tool also work for your Caterpillar C7/C9/C11/C13/C15/C32, Ford Pick-up F-650/750, Freightliner M2/Argosy, Peterbilt 379/387/385/378/357, Kenworth C500, Caterpillar 320D/312E,/312F, ect. - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09R3L5BP2 | | Brand | ANCEL | | Customer Reviews | 4.0 4.0 out of 5 stars (214) | | Date First Available | 18 Feb. 2022 | | Item Weight | 1.34 kg | | Item model number | HD3400 | | Manufacturer | ANCEL | | Manufacturer part number | HD3400 | | Model | HD3400 truck scanner | | Product Dimensions | 19.2 x 11.81 x 4.8 cm; 1.34 kg | | Special Features | Extendable, Memory, Power Folding | ## Product Details - **Automotive Fit Type:** Vehicle Specific Fit - **Brand:** ANCEL - **Global Trade Identification Number:** 00704771873374 - **Manufacturer:** ANCEL - **Operating system:** Android 4.0 - **Power source:** Corded Electric - **Product dimensions:** 19.2L x 11.8W x 4.8H centimetres - **Screen size:** 5 Inches - **UPC:** 704771873374 ## Images ![ANCEL HD3400 Pro Full System Heavy Duty Truck Scanner - DPF Regen, Free Lifetime Updates - 98% Compatibility - Diesel Diagnostic Scan Tool for Cummins, Detroit, Caterpillar, Paccar & More - Image 1](https://m.media-amazon.com/images/I/710t2-8YPiL.jpg) ![ANCEL HD3400 Pro Full System Heavy Duty Truck Scanner - DPF Regen, Free Lifetime Updates - 98% Compatibility - Diesel Diagnostic Scan Tool for Cummins, Detroit, Caterpillar, Paccar & More - Image 2](https://m.media-amazon.com/images/I/71c3PwiJNHL.jpg) ![ANCEL HD3400 Pro Full System Heavy Duty Truck Scanner - DPF Regen, Free Lifetime Updates - 98% Compatibility - Diesel Diagnostic Scan Tool for Cummins, Detroit, Caterpillar, Paccar & More - Image 3](https://m.media-amazon.com/images/I/71tOo6ksXbL.jpg) ![ANCEL HD3400 Pro Full System Heavy Duty Truck Scanner - DPF Regen, Free Lifetime Updates - 98% Compatibility - Diesel Diagnostic Scan Tool for Cummins, Detroit, Caterpillar, Paccar & More - Image 4](https://m.media-amazon.com/images/I/71hmOWOnlWL.jpg) ![ANCEL HD3400 Pro Full System Heavy Duty Truck Scanner - DPF Regen, Free Lifetime Updates - 98% Compatibility - Diesel Diagnostic Scan Tool for Cummins, Detroit, Caterpillar, Paccar & More - Image 5](https://m.media-amazon.com/images/I/715AlPIhEDL.jpg) ## Questions & Answers **Q: Does it come with a power supply?** A: No. And it doesn't require a separate power supply. It gets both power and diagnostics directly from your truck's OBD port. You can temporarily use a 12V adapte or Type-c cable (not included) to power on, but this will NOT enable vehicle diagnostics. **Q: Can it do DPF regen on all engines?** A: It supports DPF regen on major engines like Cummins, Paccar, Caterpillar, Detroit, Volvo, Mack, International/Maxxforce, Isuzu, Fuso, and Hino. Some newer Freightliner trucks with Detroit engines use the UDS protocol, which is not supported. **Q: Is this a bidirectional tool?** A: It reads/clears codes, runs DPF regen, Oil Reset and shows live data—but it does not support coding or parameter programming. **Q: Do I need Wi-Fi to use it?** A: Only for the first-time setup and updates. Once activated, it works offline with no Wi-Fi needed. **Q: What if it shows ECU error or won't connect?** A: Please check ignition, cable connection, and vehicle compatibility.

OVER CHARGE, over priced…. all it does is read code/erase.. it does describe the code but thats it… and force regen… there are units out there $80-100-200 that does what this does… waste of $449.99. Hope this helps someone not waste there hard earned money…. ## Frequently Bought Together - ANCEL HD3400 Pro Heavy Duty Truck Scanner | DPF Regeneration, Lifetime Free Update, Compatible with Commercial Vehicles with Cummins, Paccar, Caterpillar, Detroit, Volvo, Mack, International Engines - ANCEL Large Protective Case for OBD2 Scanner and Code Reader, Diagnostic Scan Tool Battery Tester, Storage Box (L) Compatible with ANCEL Products --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/498008583-ancel-hd3400-pro-full-system-heavy-duty-truck-scanner-dpf](https://www.desertcart.us/products/498008583-ancel-hd3400-pro-full-system-heavy-duty-truck-scanner-dpf) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-27*
