Q: I plugged my programmer into a car's OBDII port and it would not power up. Do I need repairs?

A: You may, but the problem may also be the car's OBD2 port.  Please try

  1. Plug-in and remove the OBDII cable a couple of different cars to test it
  2. Plug it into a wall outlet using your Update Cable. If it still will not power up,
    send it to tech support with the repair form.
Q: When I plug in my T-Code, AD-100 & MVP, a large X appears on the screen.
A: The software on your unit has been most likely been erased. This will occur when the passcode is entered into the unit incorrectly more than 3 times in a row. This can be fixed by simply updating your unit on the Internet. Click Here for step by step MVP and TCode Classic updating instructions.
Q: When I plug in my programmer, this error message appears on the screen:
"Undefined Interrupt-Vector 44-Mask 7".  What does this message mean?
A: This can occur if your software has been partially erased due to the same reason above.  To fix this problem you must update your software on the Internet.

After doing this, a large X will appear on the screen and you can proceed with the update mentioned above.
Q: How often should I update the software on my programmer and how much does it cost?
  1. If you are receiving an error message similar to "TCode / MVP Not Connected", check to make sure you have entered your pass code into the programmer and it is on the vehicle selection screen.
  2. If the download will not start it may be blocked by your virus protection or firewall software.
    Temporarily disabling these should fix the problem.
  3. If you do not have a serial port on your computer, try using a Serial / USB adaptor from
    Radio Shack (Part # 26-183). We have found this part to work on most computers.
