Cable Note: This is a software-only activation. If your original kit did not come with Non-OBDII Heavy Duty connectors (e.g., 6-pin/9-pin round connectors for trucks), you may need to purchase a Topdon HD Cable Kit separately to physically connect to older trucks.
Topdon HGV Upgrade Subscription Knowledgebase
Which Topdon tablets is this upgrade compatible with?
The Phoenix Pro series. This HGV/Commercial upgrade works with the Phoenix Max, Phoenix Smart, and Phoenix Remote. These units use the advanced MDCI Pro (or VCI) which is hardware-capable of handling the 24V protocols used by heavy duty vehicles.
Does this work on the Phoenix Lite 2 or Elite?
No, it is not compatible. The Phoenix Lite 2 and Elite do not have the hardware architecture (specifically the dual-voltage VCI capability) required to safely communicate with heavy trucks. You must own a "Smart", "Remote", or "Max" unit.
What vehicles does this upgrade cover?
Trucks, Buses, and Agri. It unlocks the software for Heavy Goods Vehicles (HGV/Trucks), Buses, Construction Machinery (Off-Highway), and Agricultural vehicles (Tractors). It covers major brands like DAF, Scania, MAN, Volvo, Mercedes Truck, John Deere, and CAT.
Do I need special cables?
Yes, you likely need the adapter kit. While the software unlocks the capability, trucks do not use the standard OBD2 port. You will need the specific 6-pin, 9-pin (Deutsch), or 12-pin manufacturer connectors. The "HGV Upgrade Kit" from Mobile Eco Tuning (MET) typically includes these adapters.
Why should I buy this upgrade from Mobile Eco Tuning (MET)?
We are commercial vehicle experts. Our company, Mobile Eco Tuning, specialises in HGV and Agricultural tuning. We don't just sell the software; we can advise you on which adapter fits a specific tractor or how to perform a forced regen on a Scania, offering support other sellers can't match.
Is this a one-time purchase?
It is an annual subscription. The purchase gives you a 1-year license for the Heavy Duty software. It allows you to download all the truck brands and updates for 12 months. After the year expires, you will need to renew the HGV license to keep receiving updates and online functions.
Can I perform DPF Regeneration on trucks?
Yes, it is a core feature. You can perform forced DPF regenerations, SCR (AdBlue) resets, and soot load resets on major truck engines (Cummins, Detroit, Paccar, etc.). This alone can save a fleet thousands in dealer call-out fees.
Does it support 24V systems safely?
Yes, the VCI handles it automatically. The VCI included with your Phoenix Max/Smart is designed to switch between 12V and 24V automatically. Once the HGV software is activated, it safely communicates with high-voltage truck systems without needing step-down converters.
Can I perform Cylinder Cut-Out tests?
Yes, essential for diagnosis. The software allows you to perform "Cylinder Cut-Out" tests to identify a weak cylinder or faulty injector on a large diesel engine without dismantling the fuel system.
Does it cover Trailer diagnostics?
Yes, for supported systems. It includes coverage for major trailer brake and suspension systems like Haldex, Wabco, and Knorr-Bremse, allowing you to diagnose ABS faults on the trailer unit itself.
How do I activate the upgrade?
It is over-the-air. Once you purchase from Mobile Eco Tuning (MET), we process your device's Serial Number. You simply connect your tablet to Wi-Fi, go to the "Update" menu, and you will see the new "Heavy Duty" or "Commercial" vehicle packages available for download.
Can I reset the Speed Limiter?
Yes, on supported models. The software allows for parameter modification on certain ECUs, including adjusting the speed limiter (Vmax) or idle shutdown timer, provided you have the necessary security access.
Does it include Wiring Diagrams for trucks?
Yes, often integrated. Just like the car software, the HGV package often includes technical data, wiring diagrams, and component locations for major truck brands, helping you trace faults in complex air and electrical systems.
Will it work on American trucks (Mack/Peterbilt)?
Yes, global coverage. The software is not just for European trucks. It has extensive coverage for US brands (Mack, Kenworth, Peterbilt, Freightliner) using J1708 and J1939 protocols, making it perfect for mixed fleets.
Can I use my car VCI for this?
Yes, it uses the same MDCI Pro. You do not need a second VCI. The same VCI you use for cars is used for trucks; the software update simply tells the VCI how to interpret the Heavy Duty protocols.
Can I pickup a Topdon HGV Upgrade near me?
Yes. If Topdon HGV Upgrade is showing in stock, it is available for collection from our Weston Super Mare store on the same day before 5pm. Next day UK delivery is also available as well as global delivery. Visit https://shop.mobileecotuning.com/shipping for more details
