Our verdict

A tablet-style bidirectional scanner with thousands of active tests and dozens of service resets for serious home mechanics and small shops. FCA gateway access and update renewal are extra, and coverage varies by vehicle.

Overview

A wireless MaxiVCI dongle plugs into the OBD port and streams data to an Android tablet, so you can walk around the car while commanding windows, fans, injectors and pumps. Autel adds full system scans, service resets and Wi-Fi printed reports.

Shop-level active tests and newer CAN FD and DoIP protocols in a handheld tablet cover far more than a code reader. The FCA AutoAuth account and update renewal after the first year are separate purchases, and function support depends on the exact car.

Who it's for

Home garages that bleed ABS, code injectors and calibrate steering angle sensors get real use from it. A casual driver checking a warning light needs only a basic reader.

Pros and cons

Pros
  • Thousands of bidirectional active tests
  • Wide service and reset coverage
  • Wireless VCI frees you from the cable
  • Wi-Fi printed pre and post scan reports
Cons
  • Update renewal after the first year
  • FCA AutoAuth sold separately
  • Battery test needs a separate tester
  • Function coverage varies by vehicle

Performance notes

Bidirectional control works by sending commands to each control module and watching the actuator respond, which pins a fault to a part rather than a circuit. Newer CAN FD and DoIP protocols are needed to talk to recent GM, Volvo, Jaguar Land Rover and BMW platforms. A wireless link means the tablet's battery and Wi-Fi strength set the working limits.
