Nov 18, 2019 Toyota products with OBD will continue to store a DTC in the ECM long term memory until the code is cleared by removing power from the ECM BATT terminal. In most cases, the EFI fuse powers this keep alive memory. Hybrid Vehicle Control Electronic Control Unit. (HV) control Electronic Control Unit (ECU).
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
3.Select the correct Interface Set up from the drop down list.
If using Techstream Lite,select Mongoose MFC
NOTE
Mongoose MFC Software and Driver MUST be installed before Mongoose MFC selection will be available.
See TIS–Diagnostics–Scan tool page for additional information
Select Mongoose MFC to Use Techstream Lite
If using TIS Techstream,select TIS Techstream VIM (this is the default)
Select TIS Techstream VIM (default )to Use TIS Techstream
4.Click OK
Toyota Techstream TIS Reprogramming ECU Flash Procedures:

B Click the Health Check button on the System Select tab
C Choose desired ECU group(s) in the Health Check dialog box
D Click Next.
E Click Continue to view Health Check result
F Available calibration updates are indicated by a Yes link in the Cal.Update? column.
Click the Yes link to acces sthe appropriate Service Bulletin onTIS
NOTE
Note:any DTCs stored in systems that will be flash reprogrammed.
Clicking the Yes link will automatically launch TIS and perform a calibration search

G Login to TIS.(If already logged in,skip this step.)
H To review the Service Bulletin and access the calibration file,click the Service Bulletin link in
the Document Title column of the Calibration Search Result portlet.
NOTE:Only Toyota Certified Technicians and above may access calibration files
2 Connect the GR8 Battery Diagnostic Station.
A Connect the GR8 Battery Diagnostic Station to the vehicle and turn it ON.
B Select Power Supply Modeby following the screen flow below
Toyota Calibration Files New
NOTICE
ECU damage may occur if the correct battery charger and mode setting are NOT used.
Power Supply Mode is used to maintain battery voltage at 13.5 volts while flash
reprogramming the vehicle.
For details on how to use the GR8 Battery Diagnostic Station,refer to the GR8
Instruction Manual located on TIS, Diagnostics–Tools & Equipment–Battery
Diagnostics.
Confirm Power Supply ModeIs Selecte
3.Click the appropriate calibration ID and reprogram the vehicle’s ECU with Techstream.
A After reviewing the procedures outlined in the selected Service Bulletin,click the appropriate calibration ID link by matching the vehicle’s current calibration ID to the Previous Calibration ID in the Calibration Identification Chart
NOTE
Calibration files are embedded as live links in the Service Bulletin.
Some vehicles require special preparation—please review the selected Service Bulletin carefully
B Click Open to load calibration file information.
NOTE
Techstream pulls calibration files as needed to ensure the latest calibration file is used.
Do NOT save calibrations locally on the hard drive or other media.
NOTICE
Errors during the flash reprogramming process scan permanently damage the vehicle ECU.
Minimize the risk by following the steps below.
1.Battery voltage MUST NOT FALL BELOW 11.4 volts during reprogramming.Confirm battery voltage is higher than 11.4 volts,but be sure voltage DOES NOT RISE ABOVE 16.0 volts duringreprogramming.
2.Turn OFF all vehicle accessories(e.g.audio system,A/C,interior lights,DRL,etc.).Do NOT add to or significantly change thev ehicle’s electrical load while reprogramming.
3.Confirm the hood is open and ensure under hood temperature does NOT exceed158◦F(70◦C).
4.Confirm cable connections between the vehicle and Techstream are secure.
5.Do NOT disconnect or turn off Techstream or vehicle ignition during reprogramming.
6.Set parking brake.
7.Complete ALL flash calibration updates provided for each ECU.
8.If the battery’s state of charge or capacity are in question,test with SST.No. 00002-V8150-KIT “Digital Battery Analyzer,”and follow Service Bulletin No. PG001-06,“Battery Maintenance for In-Stock Vehicles & Pre-Delivery”,or the appropriate “Maintenance for HV & Auxiliary Batteries ”Service Bulletin.
9.The GR8Battery Diagnostic Station MUST be used in Power Supply Mode to maintain battery voltage at 13.5 volts while flash reprogramming the vehicle.For details on how to use the GR8 Battery Diagnostic Station,refer to the GR8 Instruction Manual located on TIS, Diagnostics–Tools & Equipment–Battery Diagnostics

I Do NOT disturb the vehicle during flash reprogramming
NOTE
•ECU flash reprogramming may take anywhere from 3–30 minutes per calibration file.
•Reprogramming time will vary depending on model and ECU communication protocol.
Vehicles using CAN communication protocol will reprogram much faster (2–7minutes)
NOTE
•If vehicle requires only ONE calibration update,then proceed to step Ninthisbulletin.
•If vehicle requires a SECOND calibration update,then continue as follows:
•For serial communication vehicles,go to step J.
•For CAN communication vehicles,goto step L
J When Cal 1 has completed the update process,turn ignition OFF for a minimum of
10 seconds.Then click Next
