  • Will the CodeReader work on American, Japanese, Korean, Australian and European cars made in ALL countries?
    YES. The CodeReader is designed to work on ALL American, Japanese, Korean, Australian and European vehicles, no matter where in the world they are assembled. It will work equally well on your locally assembled American, Japanese, Korean, Australian and European vehicles, as well as on ANY variety of new or import vehicles.

     

    What about OBD ii (OBD2) / EOBD?
    The CodeReader will read codes and live data from 100% of American, Japanese, Korean, Australian and European vehicles with OBD2 / EOBD. OBD2 started in 1996 in the USA and EOBD started in 2001 for the UK.

     

    What kind of Computer / Laptop do I need to run the Rennacs CodeReader on?
    The Rennacs CodeReader UniPlug and Manual Code Reading software will run on ANY computer / laptop capable of running Windows XP, 7 or Vista.

     

    What does the Rennacs CodeReader™ / Scanner do?
    The CodeReader / Scanner speeds up your diagnosis of vehicle problems by allowing you to quickly and easily access the diagnostic fault codes and live data found in the vehicles onboard computer memory. (It generally takes less than 3 minutes to perform a test).

    It decodes the diagnostic codes and displays them in words on your Computer screen with the code number and a full description of the vehicle self diagnostic faults.
    The CodeReader is also ideal for helping to find those frustrating intermittant vehicle faults.

    It will extract codes that are stored in the vehicle computer memory even after the fault symptoms have stopped (generally when you get the vehicle to work on!).

    Another powerful use of the CodeReader is to produce a "Condition Report" of the vehicle for your customers. You can print this report directly to your normal office or workshop printer (even onto your standard letterhead if you desire!) The "Scan All Systems" feature speeds up and simplifies the process of checking all codes in the vehicle.

    Great for pre-purchase and pre-holiday checks, or for your customers who desire that bit extra on a service or tuneup. Printouts are the perfect way to justify a CodeReader machine charge.

    The Live Data feature is perfect to help isolate and diagnose faults indicated by the fault code reading.



    How does the CodeReader™ work?
    The Universal Plug (UniPlug) plugs directly into the 16 pin OBD2 / EOBD style diagnostic socket under the dash to read and erase fault codes and read live data.

    As long as you can find the diagnostic connector (the CodeReader shows you where it is), and you know the Year and Make of the vehicle you can read the codes!

    For example the CodeReader system will read the codes and data from a Subaru EFI system automatically whether its a bizarre Japanese import or a locally assembled model. It makes your life much easier!



    Does the CodeReader™ ERASE / CLEAR fault codes?
    YES. The UniPlug system automatically erases the codes for you.



    What is on the CodeReader™ PRINTOUT?
    The CodeReader Printout will display your garage name, the registration / license plate number of the vehicle, the customers name and the operator of the tool, plus a list of the fault codes found, with the number of the code and the code description.

    For example: code P1212: Airflow meter or circuit. If there are NO fault codes present, the CodeReader will printout the "No fault codes present" message. Ideal for before and after testing and diagnosis of vehicles.

    You can also print and save the Live Data results



    How does the CodeReader™ connect to the vehicle?
    The Universal Plug (UniPlug) plugs directly into the 16 pin OBD2 / EOBD style diagnostic socket under the dash to read and erase fault codes.

    The PC system has a 10 meter long cable that runs from the USB port of your computer to the vehicle under test.

    .

    How long does a CodeReader™ test take?
    The vehicle determines the speed of communication. It can take on average around 30 seconds, to greater than 2 minutes for some vehicles. The speed of your computer will not make any difference to the code reading time.



    What range of vehicles does the CodeReader™ read from?
    The CodeReader reads from vehicles 1983 to 2010 for American, Japanese, Korean, Australian and European vehicles.
