Introduction
Flash reprogramming allows the Electronic Control Unit (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.
NOTE
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:

Techstream ECU Flash Reprogramming Procedure
Process Overview
Techstream ECU flash reprogramming is a four-step process:
1.
Verify the vehicle’s applicability for recalibration and locate the 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 if the PC is connected to the Network (see figures below).
Calibration file links can be found embedded in the corresponding Service Bulletin.
Figure 3. Not Connected to a Network
Figure 4. Connected to a Network
2. Connect the DCA-8000 battery diagnostic tool using “Power Supply Mode” ONLY.
The DCA-8000 battery diagnostic tool includes a power supply mode to help maintain battery
voltage at 13.5V 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 at
TIS – Diagnostics – Reprogramming – Reference Documents.
3. Locate the appropriate calibration ID and reprogram the vehicle ECU with Techstream.
Techstream uses the CUW application to open calibration files and facilitate the ECU flash
reprogramming process.
4. Attach the Authorized Modifications Label.
Modifications to ECU calibrations MUST be recorded and properly displayed on the vehicle
using the Authorized Modifications Label.
