Techstream ECU Flash Reprogramming Procedure

Introduction

Flash reprogramming allows the ECU software to be updated without replacing the ECU. Flash
calibration updates for specific vehicle models/ECUs are released as field-fix procedures described
in individual Service Bulletins. This bulletin details the Techstream ECU flash reprogramming
process and outlines use of the Technical Information System (TIS) and the Calibration Update
Wizard (CUW) . Flash calibration updates can only be applied to the vehicle/ECU combination for
which they are intended . ECUs have internal security that will not allow them to be programmed with
another ECU 's information .
ECU
Electronic Control Unit (ECU) is a Toyota term used to describe integrated computerized devices
responsible for managing the operation of a system or subsystem. For the purposes of this
bulletin, the term "ECU" is used as a generic label for the following SAE J1930 standard references:
•

Powertrain Control Module (PCM)

• Engine Control Module (ECM)
• Transmission Control Module (TCM)
• Or any other Toyota specific control unit

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 perform ing
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 .

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 .
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.
