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.
NOTICE
• ECU damage may occur if the correct battery charger mode setting is NOT used.
• Refer to Vehicle Reprogramming Tips for other approved Chargers, located on TIS,
Diagnostics – Calibrations – Reference Documents.
3. Locate appropriate calibration ID and reprogram the vehicle ECU with Techstream.
Techstream uses the Calibration Update Wizard (CUW) application to open calibration files and
facilitate the ECU flash reprogramming process.
