TOPDON OBD2 Scanner AD900 Lite 8-inch Large Screen — Bidirectional Bluetooth & 10,000mAh Battery

Designed as a portable but powerful diagnostic partner, the AD900 Lite combines a large touchscreen, Android-based responsiveness, and bidirectional control to speed up troubleshooting. It reads and clears codes across all vehicle modules, performs active tests, and offers guided fault-code repairs. With wireless connectivity and an extended battery life, it’s built to work both in tight garage spaces and on-the-lift service bays.

How does the AD900 Lite speed up identifying vehicle problems?

Thanks to OE-level scans and bidirectional commands, the AD900 Lite goes beyond basic code reading. It retrieves ECU information, live data streams, freeze frames, and runs active tests that prompt components to operate so you can confirm faults quickly.

• Full-system scanning for Engine, Transmission, ABS, Airbag, TPMS, Steering, HVAC, and more
• Bidirectional control to activate injectors, pumps, windows, and other actuators
• Live data graphs and freeze-frame data to compare before-and-after behavior
• Instant read/clear codes and detailed ECU info for targeted troubleshooting

What wireless and power features make it practical in a busy shop?

The AD900 Lite offers Bluetooth 5.0 diagnostics with a range up to 10 meters, plus traditional VCI cables for hard-wired connections. A built-in 10,000mAh battery enables roughly 12 hours of continuous use, removing the need to stay tethered to a vehicle power port.

• Bluetooth 5.0 VCI for stable wireless communication up to 33 feet (10 m)
• VCI cable included for wired diagnostics when needed
• Large 10,000mAh battery for extended testing sessions without recharge
• Responsive Android 11.0 platform with a faster CPU for smoother operation

Which maintenance and service tasks can the scanner perform?

The AD900 Lite supports eight common reset and service procedures that technicians and DIYers use regularly. These service functions help maintain system calibrations and complete repairs after parts replacement.

• Oil reset and throttle adaptation for service intervals and idle adjustments
• EPB (electronic parking brake) and BMS (battery management) resets for replacements
• Steering angle sensor calibration and ABS bleeding to restore safety systems
• DPF regeneration and airbag reset support for emissions and safety workflows

How does the AD900 Lite support diagnostics with repair guidance?

This tool includes DTC repair-guides and expanding software coverage that provide fault-code definitions and suggested repair directions. That guidance helps technicians and hobbyists interpret codes and choose the next steps without searching multiple sources.

• Built-in DTC repair guide for many common codes and systems
• Coverage across 1996–2025 vehicles, with ongoing updates to expand models
• Multiple languages and a user interface tuned for quick navigation
