V. SEAFETY PRECAUTIONS
CRITICAL INFORMATION - READ THOROUGHLY
An ECU could be damaged if an error occurs in the communication while reprogramming the ECU. Confirm all work is
performed as described in these instructions.
1.
STABILIZE THE POWER TO THE PERSONAL COMPUTER SIDE
a) Be sure to connect the personal computer to an external AC
power supply.
NOTICE:
The ECU could be damaged if the battery voltage of the personal
computer drops while reprogramming.
b)
Turn off the screen saver and power saving mode of the personal
computer so that the power to the hard disk is kept supplied.
NOTICE:
If the screen saver or power saving mode launches while
reprogramming, the communication may be disconnected,
resulting in damage to the ECU.
2
c)
DO NOT block the ventilation opening for the cooling fan of the
personal computer.
NOTICE:
If the ventilation opening for the cooling fan is blocked with a
sheet cover or the like, the personal computer may be heated
excessively, causing the operation of the personal computer to
stop.
Due to the stop of the operation, the communication for
reprogramming signals could be stopped, resulting in damage to
the ECU.
VI. Brake/EPB SYSTEM CALIBRATION ID VERIFICATION
1.
CHECK FOR DTCs
a) Using a GTS+, click the “Health Check” button on the Main Menu.
HINT:
This Campaign covers only the software update to the Brake/EPB
System, as detailed in these instructions. It does not cover the
diagnosis or replacement of any other systems on the vehicle.
2.
CHECK CURRENT CALIBRATION
a) Locate the “Update” column of the “Calibration Information” for the Brake/EPB system on the "Health
Check Result" screen.
b) Determine the status of an available update; indicated by a YES or NO.
HINT:
If the CIDs indicate ‘Yes’, proceed with the update procedure.
3
Yes
Is there an update available for
the Brake/EPB System?
No
Campaign complete. Return the
vehicle to the customer.
Proceed to section VII. Vehicle
preparation on page 5.
◄ CRITICAL MESSAGE ►
It is critical that T-SB-0107-20 Rev. 2 in addition to the Technical Instructions for this Recall [or LSC/CSC] 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 No. 2 skid control
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.
VII. VEHICLE PREPARATION
1.
VEHICLE PREPARATION
a) Confirm the following conditions:
• Vehicle in the IG position (READY
OFF).
•
•
Transaxle in Park.
Parking brake engaged.
2.
•
•
•
Turn off all electrical accessories (i.e. climate control,
audio system, etc.)
Headlight switch in the DRL OFF position.
Windshield wiper switch in the OFF position.
STOP THE OPERATION OF THE COOLING FAN
a) Disconnect the connector from the cooling fan on the radiator fan
shroud.
b) Cover the disconnected connector with a tape, etc. to prevent
foreign material or water, etc. from adhering.
If the cooling fan runs during the Calibration
update procedure, the battery voltage will be
inconsistent and could cause damage to the
control module(s).

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 12V 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.
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 GTS+ SETUP
a) Verify that the GTS+ meets the following conditions:
•
•
•
The latest version of the software is loaded.
The GTS+ battery is fully charged. If not, connect the GTS+ to a 120V source.
The DLC III cable is in good condition.
The GTS+’s battery voltage must also be maintained during the re-flash procedure. If necessary,
plug the GTS+ into a 120V outlet during this procedure.
