Read This First

If you're only looking to diagnose the check engine light, there's a chance you may not need to rent a scanner. Your local auto parts stores like AutoZone, Advance Auto Parts, or O'Reilly may have a scanner available for you to borrow, completely free of charge. Their scanners are designed to read and clear codes from Engine Control Unit (ECU) only that activate the check engine light. However, it's important to note that these scanners are limited to only reading and clearing codes from the engine system. They won't be able to diagnose issues with other vital systems like ABS, transmission, air conditioning, air suspension, airbags, traction control, TPMS, and more.

If you require a more comprehensive diagnosis that includes all vehicle systems, including those mentioned above, then the YOUCANIC full system scanner is a valuable tool to have. This scanner can analyze your vehicle's sensors and diagnose any issues with the different systems in your vehicle, including traction control, ABS, SRS, airbags, air conditioning, ESP, TPMS, ESC, stability control, sunroof, convertible top, and more. You can also use the YOUCANIC scanner to code injectors, bleed ABS brakes, bleed SBC, raise vehicles with air suspension, register a new battery, release electronic parking brakes, and more.

    Reset Functions

    • BMS: Reset a battery after you have replaced it.
    • Brake Bleed: Keep the tires from locking up immediately when there are brakes.
    • DPF: Help you clear the blockage in the DPF filter, to meet emission standards.
    • Immo Keys: This function is mainly used to disable the lost vehicle keys and create a new replacement key fob, to protect your car from being stolen.
    • Injector: Read injector-related problems and adjusts them.
    • SAS: Calibrating and resetting the steering position is just a click away.
    •  Injector coding, Suspension, Throttle, WIN DR ROOF, Seats, Odometer, Lang Change, Headlamp, change tire size, TEC Learn, and Trans Adaption are all available for certain models. 
    • 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 oil may damage the engine. So vehicles can recalculate another optimal oil life change interval depending on the vehicle's driving conditions and climate. 
    • 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 DPF filter. When a regeneration cycle is completed, the D-P-F light automatically goes off.

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 an important 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 so as to more accurately control and adjust the throttle (or idle speed motor) action to regulate the intake of the amount. ( Kindly NOTICE: it can not only work on American cars but also support many foreign cars from Asia/Europe/China. The menu is classified by different regions. For honda, click "ASIA". For Audi, click "Europe".)
    • 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.

    Bidirectional / Active Tests

    For example, Suppose an air suspension compressor is not working and leads to a lowered vehicle. In that case, the YOUCANIC scanner can activate the air suspension compressor to help you quickly determine whether it’s a wiring, relay, or pump issue without removing any parts.

    Why do I have to pay for this? A local auto parts store will diagnose my car for free. 

    Scanners used by local auto parts stores such as Advance and AutoZone are not full system professional level scanners. Those scanners will diagnose your Engine Control Unit (ECU). That is only one of your car's possible thirty or more control units. So if you have problems with airbags, transmission, climate control, ABS, blind spot system, etc., the local auto parts scanner will not help. 

    Can I use the scanner in more than one car? 

    Yes. Use it in as many cars as possible In fact; we want you to help your friends, family, and neighbors while you have the scanner. 

    Why should I not take my car to the dealer? 

    You can if you have the time and want to pay twice as much. Most dealerships will charge a full-hour rate; during that time, they do all they do is read and look at the codes. That's pretty standard.  We also have a platform where our ASE-certified mechanics give you feedback on your codes. It's free to use. Just take a few pics of the codes and post them up to get help. 

    Can I diagnose my car? I have never used a scanner before.

    We will diagnose one car free of charge. Once you get the scanner, we can remotely connect to the vehicle and do a full scan and health check. Please contact us to set up a time when a technician can remotely connect to the vehicle.

      Clayton Greene (West Virginia, United States)
      Youcanic bliss

      I rented the scanner to troubleshoot my 2012 Mercedes GL550, no start problem. I was skeptical until I tried it. I was able view the real-time data as I turned to key in the ISM, which showed me that the ISM was not sending the signal to the start relay to allow it to start. I was able to repair the ISM, that had a broken connector and was able to see the signal from the ISM to the relay. The car still wouldn't start, so I went further, and found that the starter was also bad. I was very pleased to save a bunch of money, even with the rental fee,taken into consideration.
      The only thing I had an issue with was the fact that the scanner wasn't able to test the starter, which I had to remove and het tested. I liked it so much that I bought one, with no hesitation. Even woth the purchase price plus the rental fee, it was much cheaper than letting the Dealer/Stealer fix the problems. Lol

      Great Deal

      Great deal to rent a super easy scanner for those pesky modules. I used mine on Volvo's SRS module and it worked great. Wish you could use its email functionality to send yourself diagnostics, and returning the rental should be an easier process (shouldnt have to email to get the label). But otherwise, a great deal.

      Dennis J. (Connecticut, United States)
      Ucan-2 scanner rental

      I highly recommend this to the home mechanic. I had a few issues to sort out on my 08 volvo and this was the way to finish out my work.
      I set the transmission to learn, recalibrate the ac system, sorted out my haldex AWD, got rid of my airbag warning, and cleared up a traction control issue.
      Plus cleared out old codes from over the years.
      It's easy to use and was in new condition.
      The company is easy to work with also.

      Kyle F (Tennessee, United States)
      No issues with renting.

      The whole process went very smoothly from beginning to end. Before renting I asked if the tool could do what I needed to and tech support confirmed it could. Renting was straightforward and the tool was easy enough to use. Did not need to schedule a remote tech support session. Once I was done with the tool I emailed them asking for a return label which was they promptly emailed me. Got my refund when they received their tool back. 10 out of 10 would rent from them again.

      Awesome product glad you have this

      Jim W. (Maryland, United States)

      One of my cars is a 2010 Mercedes S400 and have used YOUCANIC in the past.

      YOUCANIC sent me a remote diagnostic scanner (for a small fee) and it took less than 2 minutes to hook up. They were able remotely to tell me I needed a new adjustable strut and there were no other problems. I saved a trip to the Mercedes dealership and probably $125-$150 in cost. Also, they recommended the adjustable strut to buy (comes with lifetime warranty). I called the Mercedes dealership and was told the strut cost $1,400 ( no lifetime warranty) and $800 to install. I bought the strut recommend by Youcanic (lifetime warranty) for $475 and paid $300 to install.

      The Youcanic remote diagnostic scanner works for any vehicle sold in USA.

      Jeremy Smith (Maryland, United States)
      Saved me time and money

      Rented the scanner. It arrived in 3 days. Was able to read the codes and YOUCANIC team even provided feedback on those fault codes. The problem ened up being the ABS wheel speed sensor at the front right. Shipped the scanner back and got my deposit back. Saved some money compared to going to the dealer.
