# TOPDON AD900 Lite Wireless Bidirectional OBD2 Scanner, 8-inch Screen

The TOPDON AD900 Lite is a wireless bidirectional OBD2 diagnostic scanner with an 8-inch touchscreen, full-system scan functions and active tests. Its larger tablet-style format and service resets suit hands-on diagnosis, but vehicle compatibility and the advertised configuration should be confirmed before purchase.

## At a glance

- Bidirectional control sends commands for active tests of supported vehicle components.
- Wireless VCI is intended to let you move around the vehicle while diagnosing, with a claimed range of up to 10 metres.
- Full-system functions include reading and clearing codes, live data and freeze-frame retrieval where modules are available.
- The eight listed service functions cover several common maintenance and reset tasks.

## Pros

- Large 8-inch screen provides more display area for diagnostic information.
- Combines active tests with code, live-data and freeze-frame functions in one diagnostic tool.
- The listed resets span oil, EPB, steering angle, DPF, ABS, battery-management and airbag functions.

## Cons

- Vehicle and function coverage can depend on the specific car and available modules, so universal-fit wording does not guarantee compatibility.

## Before you buy

- Listing details are contradictory or unconfirmed: the headline identifies the unit as AD900 Lite and specifications give model 900L-G, while feature copy also calls it ArtiDiag900 Lite and claims Android 11.0, a 10,000mAh battery and 12 hours of operation, whereas the specifications list Android 10.0 and do not confirm battery capacity or runtime. Check the selected version and vehicle/function compatibility before buying. Battery testing is optional and requires the separately identified BTMobile ProS, and the DTC repair guide is stated to cover Chrysler, Dodge, Jeep and Fiat models from 2010–2014.

## A good fit for

- DIY users wanting code reading, live data, freeze-frame information and active tests in a tablet-style scanner.
- Repair settings where wireless movement around a vehicle and the listed reset functions are useful.

## Less suited to

- Buyers who need confirmed compatibility with a particular vehicle or diagnostic function without checking coverage first.
- Anyone expecting battery testing from the scanner alone, as the listing describes it as an optional separate-analyser capability.

## Customer feedback

Customer feedback highlights readability and value, while reports on connectivity, functionality, ease of use and battery life are mixed. For buyers relying on the wireless VCI during active tests, the mixed connectivity feedback matters. The listing claims Bluetooth 5.0 and up to 10 metres, but those specifications do not settle individual connection experiences.
- Positive themes: Customers report that the tool is easy to read and consider it good value.
- Mixed feedback: Connectivity feedback is mixed, including reports of wireless connection issues despite praise for the dongle.
- Mixed feedback: Feedback on functionality, ease of use and battery life is also mixed.

## Frequently asked questions

### Can the AD900 Lite run active tests?
The listing describes bidirectional control for active tests, allowing commands to be sent to supported vehicle components. Confirm that the desired test is supported for your vehicle.
### Does it diagnose every system on every car?
The listing claims full-system diagnostics for available modules, but coverage depends on the vehicle and modules. Check compatibility for your car and required functions before purchase.
### Is battery testing built in?
Battery testing is described as optional and requires the separately identified BTMobile ProS analyser. It is not presented as a capability of the scanner by itself.
### Which Android version and battery runtime should I expect?
The details list Android 10.0, while feature copy claims Android 11.0 and 12 hours of continuous operation from a 10,000mAh battery. These claims conflict, so confirm the selected version with the listing.
