The XTOOL AD20 wireless code reader and scan tool provides comprehensive OBD2 diagnostics, allowing you to perform 10 essential tests:

Read Trouble Codes, Clear Trouble Codes, View Live Data, Read Freeze Frame Data, I/M Readiness Check, On-Board Monitor Testing, O2 Sensor Monitoring, Component Testing, Retrieve Vehicle Information, Modules Present Check.

The XTOOL AD20 supports engine diagnostics, including detecting error codes related to the check engine light. It can identify and read engine-specific error codes to help you address issues promptly.

When paired with your car and left plugged into the OBDII port, the AD20 acts as a powerful engine analyzer. It provides a Performance Test Trip feature that helps you monitor crucial parameters such as acceleration, fuel efficiency, coolant temperature, engine speed, and voltage. The device also sends alert messages if it detects high coolant temperatures or OBD2 fault codes while driving.

The Smart Dash feature projects engine information onto your windshield, eliminating the need to look down at the dashboard and allowing for safer driving. Unlike many Bluetooth OBD2 readers that only work with OBD2 data, the AD20’s Smart Dash transforms your mobile device into a digital dashboard, enhancing both safety and convenience.

With the AD20, you can easily monitor your vehicle's battery condition at any time. Simply tap the car switch on the app to view the real-time test data.

Each trip's data is accompanied by a detailed analysis, covering driving time, distance, average fuel consumption (for reference only), average speed, and maximum speed.

The Advancer AD20 offers lifetime free updates, lifetime technical support, and lifetime online service, with no subscription fees or hidden costs.
