Frequently Asked Questions
Everything you need to know.
Is the software updated regularly? Are updates free?
Yes. UR300 includes lifetime free software upgrades. No annual subscription required.
What's the difference between UR300 and the MA200 Plus?
The key difference lies in functional depth and advanced capabilities. The UR300 is an advanced, high-tier diagnostic tool featuring bidirectional control (active tests), ECU coding, and 48 service reset functions. The MA200 Plus is a cost-effective, DIY-focused tool designed for all-system code scanning and 6 essential service reset functions.
The UR300 cannot recognize my vehicle by AutoVIN, does it mean the device is faulty?
Not necessarily. Send your VIN to our support team and we'll confirm AutoVIN compatibility within 24 hours. In the meantime, you can manually select your vehicle model — all diagnostic functions will still work normally. We'll add your VIN to our database in the next update.
DTCs can be read normally but fail to be cleared or reappear after clearance, why?
Please keep ignition on and engine off. Record freeze frame data first before clearing codes.
Persistent hardware faults need physical repair prior to code clearance.
Some fault codes of systems like SRS and ABS can only be cleared after finishing bidirectional tests.
