*b

Package (CUW) File #1

*c

Package (CUW) File #2

a) The CUW file is a package file that contains
several programs that reprogram ECUs, and
one CUW package is capable of
reprogramming multiple ECUs successively

NOTICE:
All the ECUs must be reprogrammed.

◄ CRITICAL MESSAGE ►
It is critical that T-SB-0134-16 and T-SB-0107-20 in addition to the Technical Instructions for this LSC are followed.
This TSB outlines all steps necessary to prevent reprogramming failure. Toyota will not provide reimbursement coverage
for reprogramming failures if this TSB is not followed. If you have a reprogramming failure that requires ECU
replacement and the Technical Instructions and TSB were followed correctly, please create a case with the Technical
Assistance Hotline documenting all information related to the failure. If sufficient reporting is received related to re-flash
failure, there will be consideration for reimbursement.

VIII.

VEHICLE PREPERATION

1. PLACE VEHICLE IN “POWER ON”, “READY OFF”
a) Press the power button until “POWER ON” and “Not Ready to Drive” is displayed on the dash

2.

CONFIRM ALL ELECTRICAL LOADS ARE OFF
• Vehicle in the IG position
•
(READY OFF).
•
• Transaxle in Park.
• Parking brake engaged.
•

Turn off all electrical accessories (i.e. climate control,
audio system, etc.)
Headlight switch in the DRL OFF position. (w/ DRL
OFF position)
Windshield wiper switch in the OFF position.

a) When the vehicle has no “OFF position” in the light control switch:
1) Turn the IG ON.
2) Set the light control switch to the AUTO position and make sure
that the exterior lights are turned on.
3) Light up the automatic light control sensor with work light to
keep the exterior lights turned off.

3. CONNECT THE 12V BATTERY TO A POWER SUPPLY
a) Connect the DCA-8000 or other type of a power supply (not a battery charger) to the 12 V battery.
b) Tap the Reflash icon from the Main Menu screen of the DCA-8000.
A power supply MUST be used during reprogramming. ECU damage will occur if the battery
voltage is not properly maintained during this re-flash procedure. This procedure takes 2 hours
with the vehicle on and battery power supply is crucial.
NOTICE:
A power supply must be connected directly to the 12V battery terminals and NOT the remote jump posts
under the hood (if equipped).

4. VERIFY TECHSTREAM SETUP
a) Verify that the Techstream meets the following conditions:
• The latest version of software is loaded.
• The Techstream battery is fully charged. If not, connect the Techstream to a 120 V source.
• The DLCIII cable is in good condition.
7

The Techstream’s battery voltage must also be maintained during the re-flash procedure. Plug
the Techstream into a 120 v outlet during this procedure. This procedure takes 2 hours with the
Techstream on and the battery power supply is crucial.
NOTICE:
If the Techstream communication with the vehicle fails during the re-flash procedure, the ECU will be
damaged.

IX. UPDATE CALIBRATION
NOTICE:
While reprogramming, keep IG ON. Never turn the IG off or ENGINE-START.
As reprogramming completes in approximately a maximum of five minutes per ECU, stay near the vehicle and
DO NOT allow anyone to operate the vehicle or Techstream in order to prevent troubles from occurring.
Pressing the “Cancel” button or the “X” button on the top right means to cancel reprogramming and could
damage the ECU while reprogramming. Be sure to press “Retry” to continue reprogramming.

1. DOUBLE-CLICK THE DOWNLOADED PROGRAM PACKAGE
a) Start reprogramming with package 1
b) When all reprogramming steps are completed for package 1 you
will restart the process with package 2

2. IF THE SCREEN ON THE LEFT IS DISPLAYED, CLICK “CURRENT
CUW”

3. LAUNCH CALIBRATION WIZARD
a) Select Next

8

5. SELECT A DEVICE TOOL
a) Select “Next”

6.

CONFIRM THAT EACH “NEW CAL ID” IS CORRECT, AND
THEN CLICK ON “NEXT”
a) Refer to calibration and reprogramming ID list in section VI step 2

7.

FOLLOW THE ON-SCREEN INSTRUCTIONS

8.

FOLLOW THE ON-SCREEN INSTRUCTIONS
NOTICE: DO NOT turn the IG ON with the brake pedal depressed.

9

9.

PERFORM SECURITY SIGNATURE TO THE SERVER
a) Follow the instructions on screen

Hint: The reprogramming will not begin without the security
signature

10. LOG IN TO TIS
a) Input TIS login credentials and select “Login”
Note: This step requires internet.

11. PERFORM SECURITY SIGNATURE TO THE SERVER
a) Input TIS login credentials and select “Login”

12. PERFORM SECURITY SIGNATURE TO THE SERVER
a) Select “Send”

13. COPY SIGNATURE FROM TIS
a) Select “Copy to Clipboard”

10

14. PASTE SIGNATURE INTO TECHSTREAM
a) Select “Next”

15. DUE TO COMMUNICATION BETWEEN ECUs BEING LOST
DURING REPRGORAMMING THE HEADLIGHTS MAY
TURN ON AS A FAIL-SAFE.
a) Do not cover the headlights
b) If the headlights turn on they cannot be turned off

16. RECALIBRATION WILL NOW BEGIN
Notice: Only one ECU in the package will be reprogramed at a
time.

11

17. CALIBRATION UPDAED
a) The following Screens will appear at the end of each reflash.
b) Press a key or operate the mouse to close the window.

18. REPEAT PROGRAMMING STEPS FOR EACH CAL ID IN THE PROGRAM PACKAGE
a) The IG OFF and ON operation and the security signature verification need to be conducted whenever the
Calibration process finishes. Follow the instructions shown on the screen.
19. AFTER REPROGRAMMING, MAKE SURE THAT THE
“CURRENT CAL ID” IS CORRECT

12

20. USE THE CHECKSHEET TO TRACK UPDATES AND
CONFIRM ALL CAL IDs HAVE BEEN UPDATED
a) Check the corresponding box off on the check sheet as the
reprogramming has finished. (Make a copy of the applicable
check sheet located in the appendix and use it)
*a

DO NOT skip reprogramming.

X. SEND VEHCILE INFORMATION
1. PERFORM VERIFICATION HEALTH CHECK
a) Using a Techstream, perform a Health Check.
b) Clear DTC’s that may have set during the re-flash procedure.
c) Re-run the Health Check to confirm that no DTC’s reappear.
THIS VERIFICATION HEALTH CHECK IS
NECESSARY to update the results and CID’s
to the National database.

2. COMPLETE ECU UPDATE AUTHENTICATION
a) Input TIS Credentials
HINT: Health check will complete once TIS credentials have been entered

Repeat the programming steps for the remaining ECUs (systems) using the downloaded
reprogramming package 2 (.cuw) files.
