Bi-directional Support

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.

For 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 vehicle or determine whether there is a problem with the air compressor. 

Here are a few examples of active tests which 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.

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 gets 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 the forced regen cleaning to clear the blockage through continuous burning of 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 is to initialize the car's throttle actuators so that the learning value of the ECU returns to the initial state to more accurately control and adjust the throttle (or idle speed motor) action 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.

    Worth the money

    The scanner is user-friendly and offers a variety of functionalities and updates, making it worth the investment. I used it to check the air suspension on my Mercedes S-Class which ended up being a bad air suspension compressor. I was able to performed a full health check of the car and look at 46 control modules. It has additional features beyond reading and resetting codes but I haven't explored those much. Its convenient that it allows you to directly click on error codes and be directed to the web for more information. It was easy to set up and register. Updates are supper easy but the scanner does work out of the box and has all make software preloaded. The customer support is great. I also took it to a car auction this past week and was able to run full system scans on five different cars. That alone helped me eleminate 3 of the 5 cars I was looking to buy. I am very satisfied with its performance so far.

    Saved me money on the first diagnostic

    Found and cleared codes in the seat massage function of our Mercedes S Class. The pump that operates the massage features was not running even when out of the car and on the bench. This tool found codes, cleared them, and the pump now operates. $820 pump + who knows how much to have the codes cleared, versus $499 diagnostic tool, equals at least $321 savings.

    Works on Porsche!

    Used it right away on a 2014 Porsche Cayenne GTS. Was able to reset the oil change warning and diagnosed a faulty rear drivers door lock actuator. Very cool that the device allows you run a test and it unlocks and locks the doors and then tells you with codes that there is a problem back there.
