Approved J2534 Devices only provide reprogramming capabilities and do not support diagnostic scantool functions. For full diagnostic capabilities, please consider TIS Techstream or Techstream Lite
Toyota, Scion, and Lexus ECMs can be reprogrammed with the TIS Techstream, Techstream Lite, Diagnostic Tester, or can also be reprogrammed using a Toyota validated J2534 interface. Vehicle recalibration requires the use of the following:
- Toyota validated J2534 interface
- TIS Professional Level Subscription
- Toyota Calibration Update Wizard software (installed along with Techstream Software)
- Personal Computer running Microsoft Windows XP/2000 or later operating system
Toyota strongly recommends USING ONLY VALIDATED INTERFACE DEVICES that appear on this list.
