Question:
I’m going to buy a Topdon Artidiag800 BT 2 diagnostic scanner when the 2 year subscription runs out will the biderectinal function still work and what other features might I lose?
Answer:
The new AD800 BT2 supports bi-directional control and comes with 2 years of free updates. Once the subscription period ends, the Bi-directional control will still work. Even if the subscription expires, most basic diagnostic functions on your device can still be used offline. For example, you can read and clear trouble codes, view some live data streams, and perform basic functions that don’t require server authorization. These operations rely mainly on the vehicle’s own ECU data, so they don’t need an internet connection. You’ll still have access to the vehicle software versions available before the expiration date.
After the software update expires, new versions released afterward cannot be updated (software released before the expiration can still be downloaded normally). However, some advanced features—like matching, adaptation, online coding, brand-level special functions that require server authorization, firmware updates, and vehicle software updates—will not be available offline. Also, for vehicles that require online gateway unlocking (like SGW or FAG), those functions cannot be executed without being online. For instance, on Chrysler vehicles from 2018 onwards, offline access may restrict trouble code retrieval, live data, module information, active tests, special functions, and online coding.
Question:
How does this differ from the 800BT2 that has free lifetime updates?
Answer:
The lifetime free update version AD800 BT2 (older version) doesn’t include bi-directional control function.
