PROCESS OVERVIEW

Techstream ECU flash reprogramming is a 4-step process:

  1. Verify the vehicle's applicability for recalibration and locate desired calibration file by performing the Techstream Health Check function.
    NOTE: Techstream will automatically search TIS for the appropriate Service Bulletin using the current Calibration ID from the vehicle. Calibration file links can be found embedded in the corresponding Service Bulletin.
  2. Connect the GR8 Battery Diagnostic Station using "Power Supply Mode" only.

    The GR8 Battery Diagnostic Station includes a Power Supply Mode to help maintain battery voltage at 13.5 volts during ECU reprogramming.

    NOTE: ECU damage may occur if the correct battery charger mode setting is NOT used.
  3. Perform the RAV4 EV ECU software update using the Tesla Powertrain Service Diagnostics program.

    Launch the Tesla Powertrain Service Diagnostics program and initiate the update process to complete the reprogramming.

  4. Attach the Authorized Vehicle Modification Label.

    Modifications to ECU calibrations MUST be recorded and properly displayed on the vehicle using the Authorized Modification Label.
