TECHSTREAM PREPARATION
Selecting the Correct VIM
Techstream software requires a VIM selection before it can be used for reprogramming.
Perform the following:
- Select Setup from the Techstream Main Menu screen.
- Select VIM
Select from the Setup drop down menu.
- Select the correct Interface Setup from the drop down list.
For Techstream 2.0, select MongoosePro MFC .
NOTE: Mongoose Driver MUST be installed before Mongoose selections will be available.
Refer to the Technical Information System (TIS), Diagnostics - Scantool page for additional information. - Click OK .
PROCESS OVERVIEW
Techstream ECU flash reprogramming is a 4-step process:
- 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.
- 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. - 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.
- Attach the Authorized Vehicle Modification Label.
Modifications to ECU calibrations MUST be recorded and properly displayed on the vehicle using the Authorized Modification Label.
OPERATION PROCEDURE
- Verify the vehicle's applicability for recalibration and locate desired calibration file.
- Connect Techstream and establish a vehicle connection.
- Click the Health Check
button on the System Select
tab.
