II. IDENTIFICATION OF AFFECTED VEHICLES
1. CHECK VEHICLE FOR CAMPAIGN ELIGIBILITY
a) Compare the vehicles VIN to the VIN listed on the Repair Order to ensure they match.
b) Check the TIS Vehicle Inquiry System to confirm the VIN is involved in this recall, and that it has not already been completed.
NOTICE:
TMNA warranty will not reimburse dealers for repairs completed on vehicles that are not affected or were previously completed, even by another dealer.
III. PREPARATION
A. TOOLS & EQUIPMENT
• Standard Hand Tools
• DCA-8000 Battery Diagnostic Station
• T-SB-0134-16
• T-SB-0107-20
• Techstream ADVi / Techstream 2.0 / Techstream Lite

IV. BACKGROUND
The subject vehicles are equipped with a 12.3-inch Thin Film Transistor (TFT) Liquid Crystal Display (LCD) monitor, which is used to display various information such as warning and indicator lights, vehicle gauges, messages and more. The LCD monitor can go blank due to a software issue. A blank monitor creates a noncompliance with certain federal requirements. This can reduce the driver’s recognition of certain operating conditions, which can lead to an increased risk of a crash.
V. SAFETY 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 the damage of the ECU.
3
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 the damage of the ECU.
VI. COMBINATION METER ASSEMBLY CALIBRATION ID VERIFICATION
1. CHECK FOR DTC’S
a) Using a Techstream, perform a Health Check to check for any Diagnostic Trouble Codes.
NOTICE:
This Campaign covers only the software update to the Combination Meter System, as detailed in these instructions. It does not cover the diagnosis or replacement of any other systems on the vehicle.
NOTE:
Before completing Health Check, “Send Vehicle Information” window may be displayed. If displayed, then click “Yes” to send the vehicle information.
• If “Failed to send data to the server” is displayed, click “No” to close the window and proceed to the next step.
4
2. CHECK CURRENT CALIBRATION
a) Locate the Update column for the Combination Meter System in the Stored Data tab for this vehicle.
b) Determine the status of an available update; indicated by a YES or NO.
HINT:
If the CID’s indicate ‘Yes’, proceed with the update procedure.
◄ CRITICAL MESSAGE ►
It is critical that T-SB-0134-16 and T-SB-0107-20 in addition to the Technical Instructions for this Safety Recall 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 Combination Meter 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 PREPERATION
1. VEHICLE PREPARATION
a) Confirm the following conditions:
• Vehicle in the IG position (engine 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.
• Windshield wiper switch in the OFF position.
Is there an update available for the Combination Meter System?
Campaign complete. Return the vehicle to the customer.

2. HYBRID MODEL ONLY: STOP THE OPERATION OF THE ELECTRIC FAN
a. Disconnect the connector from the cooling fan.
NOTE:
• DO NOT pull from the wire side.
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.
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.
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.
The Techstream’s battery voltage must also be maintained during the re-flash procedure. If necessary, plug the Techstream into a 120v outlet during this procedure.
NOTICE:
If the Techstream communication with the vehicle fails during the re-flash procedure, the Combination Meter ECU will be damaged.
