How to use Toyota Techstream TIS Reprogramming ECU Flash

This article introduce the procedures of Techstream TIS ECU Flash Reprogramming.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.

PS: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:

1.Powertrain Control Module (PCM)

2.Engine Control Module (ECM)

3.Transmission Control Module (TCM)

4.Or any other Toyota specific control unit

 

What vehicle models this guide applicability:

Year from:2001-2013

Vehicle models:4Runner, Avalon, Camry, Camry HV, Celica, Corolla, Echo, FJ Cruiser, Highlander, Highlander HV, Land Cruiser, MR2 Spyder, Matrix, Prius, Prius C, Prius PHV, Prius V, RAV4, Sequoia, Sienna, Solara, Tacoma, Tundra, Venza, Yaris

 

Techstream ECU flash reprogramming is a 4-step process:
1.Verify the vehicle’s applicability for recalib ration 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 Stationusing “PowerSupplyMode”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 withTechstream. 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

 

Techstream ECU Flashing Preparation:

Selecting the TIS Techstream VIM or the Mongoose MFC VIM.
Techstream software requiresa VIM selection before you can use the Mongoose MFC VIM.
If using TIS Techstream,no changes are needed.
Perform the following:
1.Select Setup from the Techstream Main Menu screen.
2.Select VIM Select from the Set up drop down menu
