Bi-directional / Active Tests

Featuring bi-directional control, the YOUCANIC scanner can read any ECU data and monitor the operation of the actuators. This bi-directional diagnostic scanner can precisely locate car problems through active tests, also called actuator tests, letting you quickly know whether a specific system, component, or subsystem is functioning correctly.

Example: If an air suspension compressor is not working and leads to a lowered vehicle, the YOUCANIC scanner can activate the air suspension compressor to help you raise the car or determine whether there is a problem with the air compressor. 

Here are a few examples of active tests that can help you test components, sensors, and switches:

  • Test air suspension compressor
  • Turn the a/c clutch on and off;
  • Switch the interior lights on and off;
  • Perform an evaporative emissions leak test
  • Activate folding side mirrors, exterior mirrors
  • Test adaptive headlamp
  • Test window regulators and motors. 
  • Activate the window up or down. 
  • Turn on/off the radiator fan/interior & exterior lights

  • Operate Mirrors/Fuel Injector Balance/ Injector Buzz Test, Door Lock/Window/Horn/ Light/ Headlamp Test,
  • and a lot more. 

    40+ Maintenance & Reset Functions

    • ABS Bleeding: ABS brake bleeding to get a firm brake pad after repairing the ABS pump system. 
    • Oil Light Reset: reset the Oil Life Reminder (turn off the Oil Service Light) when the replacement of engine oil is done in case of the impurities in the oil may damage the engine so vehicles can recalculate another optimal oil life change interval depending on the vehicle's driving conditions and climate. Your driving safety is also ensured.
    • Crankshaft/Camshaft Relearn: The crankshaft position sensor (CKP) is a magnetic induction sensor, the function of which is to determine the position of the crankshaft. It will help you know which cylinder piston is at the top dead center to determine the ignition time and detect the crankshaft's rotation angle (engine speed sensor). This function must be done after the engine has replaced the ECU and disassembled or replaced the timing belt assembly and crankshaft position sensor.
    • DPF Regeneration (Diesel Particulate Filter Regeneration) lets you perform forced regen cleaning to clear the blockage by continuously burning the particulates captured in the D-P-F filter. When a regeneration cycle is completed, the D-P-F light automatically goes off.
    • EPB Reset: (Electronic Parking Brake Reset) This function can maintain the electronic braking system safely and effectively. The applications include deactivating and activating the brake control system, assisting with brake fluid control, opening and closing brake pads, setting brakes after disc or pad replacement, and so on.
    • Battery Registration: Allows the scan tool to evaluate the battery charge state, monitor the close-circuit current, register the battery replacement, and activate the rest state of the vehicle.
    • SAS Calibration: (Steering Angle Sensor Calibration) Steering wheel angle sensor, a vehicle stability control system component, is mainly installed in the direction column below the steering wheel. It helps clear faulty steering angle sensor memories and plays a vital role in steering angle sensor calibration.
    • Throttle Body Relearn: Throttle matching initializes the car's throttle actuators so that the learning value of the ECU returns to the initial state to control and adjust the throttle (or idle speed motor) action more accurately to regulate the intake amount.
    • Electronic Park Brake: Release the electronic parking brake to replace the rear brake pads and rotors. 
    • TPMS Reset: (Tire Pressure System Reset ) When the car tire pressure failure indicator light is on, low or leaking tire pressure is, replacement or installation of TPMS equipment, replacement of tires, damage to the tire pressure sensor, etc. need to do TPMS reset after maintenance.TPMS Service: Looks up the tire sensor IDs from the vehicle's ECU and performs TPMS sensor relearn procedures after tire sensors are replaced.

    Not all reset functions apply to all vehicle makes and models. For example, battery registration is mainly for BMW and MINI. Most other makes and models do not require battery registration.

      Geny Rojas (Florida, United States)
      The Best Scanner

      Thank you for your business. Thank you for your Invention. I Can Be My Own Mechanic.


      Works great! Way more than I needed or expected. But then again, I don’t buy cheap stuff.

      CHRISTOPHER CODY (Michigan, United States)
      Scan Tool (Christopher)

      Definitely enjoying this unit. So far, it has performed well alongside our Matco Maximus (10x the price.) The video scope is nothing to write home about. I would suggest is an option for an oscilloscope and any software required. I would gladly purchase.

      ALFONSO SANCHEZ (California, United States)

      Worked as advertised and the YouTube videos are very helpful. Replaced a set of rear air springs on a MB 450 GLS and used the scanner to inflate the new air springs and reset the air system.

      Derek Robinson (Florida, United States)
      Best scan tool I've ever owned. Bar NONE.

      I've been buy, updating, upgrading and (trying) to use scan tools since OBD became standard and I can tell you all....THIS ONE IS THE BEST!

      George baranowski (Illinois, United States)
      Not bad for a non OEM scanner

      Overall I have to say the UCAN-II-B PRO Full System Scanner did what was advertised, but I wish it had a few more Active Test features (like Opening and Closing the Convertible Top flaps on a R230 MB.)


      Excellent product at excellent price.

      David Anderson (California, United States)
      Quite The Machine!

      It is capable of doing great things, I am still learning, but what it can do, surpasses the other scan tools.

      Geary Alferes (California, United States)
      MB airbag reset

      About every 4 to five months my passenger airbag side in my sprinter van light comes on…the dealer says everything is good then they reset for $150 this has happened twice before, I made my purchase when it happened for the time. The UCANIC work perfectly \

      E.V. (Bacău County, Romania)
