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

3. Select the correct Interface Setup from the drop down list.
• If using Techstream 2.0, select MongoosePro MFC.
• If using Techstream Lite, select Mongoose MFC, MongoosePro MFC, or MongoosePro
MFC2 (green) depending on the cable being used.
NOTE
Mongoose Driver MUST be installed before Mongoose selections will be available.
See TIS – Diagnostics – Scantool page for additional information.
4. Click OK.
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.

B. Click Open to load calibration file information.
Figure 9.
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 can permanently damage the vehicle ECU.
Minimize the risk by following the steps below.
• Battery voltage MUST NOT FALL BELOW 11.8 volts during reprogramming. Confirm
battery voltage is higher than 11.8 volts, but be sure voltage DOES NOT RISE ABOVE
16.0 volts during reprogramming.
• Turn OFF all vehicle accessories (e.g. audio system, A/C, interior lights, DRL, etc.). Do
NOT add to or significantly change the vehicle’s electrical load while reprogramming.
• Confirm the hood is open and ensure under hood temperature does NOT exceed 158◦F
(70◦C).
• Confirm cable connections between the vehicle and Techstream are secure.
• Do NOT disconnect or turn off Techstream or vehicle ignition during reprogramming.
• Set parking brake.
• Complete ALL flash calibration updates provided for each ECU.
• 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.
• The GR8 Battery 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.

H. 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 – 7 minutes).
Figure 15.
NOTE
• If vehicle requires only ONE calibration update, then proceed to step N in this bulletin.
• If vehicle requires a SECOND calibration update, then continue as follows:
• For serial communication vehicles, go to step I.
• For CAN communication vehicles, go to step K.
