IV. BACKGROUND
The subject vehicles’ transmission has improper programming that could lead a component to unnecessarily
cycle and experience abnormal wear. If this component becomes damaged, the malfunction indicator lamp
may illuminate in the instrument cluster and the vehicle could experience a reduction of speed. After
reaching a pre-determined gear ratio, the vehicle can be operated up to approximately 37 mph.
CRITICAL INFORMATION - READ THOROUGHLY
An ECM could be damaged if an error occurs in the communication while reprogramming the ECM.
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.
NOTE:
The ECM could be damaged if the battery voltage of the personal
computer drops while reprogramming.
b) Exit all applications except Techstream 2.0 (TIS Techstream /
Techstream Lite).
c) Turn off the screen saver and power saving mode of the personal
computer so that the power to the hard disk is kept supplied.
NOTE:
If the screen saver or power saving mode launches while
reprogramming, the communication may be disconnected,
resulting in the damage of the ECM.
d) DO NOT block the ventilation opening for the cooling fan of the
personal computer.
NOTE:
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 ECM.

V. ECM CALIBRATION ID VERIFICATION AND DTC CHECK
1. CHECK FOR DTC’S
a. Using a Techstream, perform a Health Check to check for
any Diagnostic Trouble Codes.
b. If DTC P2820 is present, take a screenshot of the
vehicle Health Check to prove DTC P2820 is present.
An example of this screenshot is shown below.
c. CVT assembly replacement is required at this point.
Toyota will require this screenshot prior to releasing parts
for this repair. Refer to the Dealer Letter for complete parts
ordering instructions.
• Parts will not be released if screenshot of
Health Check is not provided.
d. If CVT assembly replacement is required, see T-SB-028917 (Toyota) or S-SB-0002-18 (Scion) for repair
instructions.
Note: This Service Campaign covers only the ECM reflash,
as detailed in these instructions. It does not cover the
diagnosis or replacement of any other parts on the vehicle.
• Example of required screenshot:
VIN and DTC P2820
• If vehicle is out-of-warranty, DSPM authorization is required prior to proceeding
with CVT assembly replacement. Refer to the Dealer Letter for further instructions.

1.
VEHICLE PREP
a. Prior to vehicle shut down preform the following steps:
• Vehicle in the IG on position.
• Transaxle in the P range.
• Parking brake engaged.
• Turn off all electrical accessories (i.e. climate control, audio system, etc.)
b. Headlight switch in the DRL OFF position.
c. Turn off the vehicle.
2. CONNECT THE GR8
a. Set the GR8 to Power Supply Mode to help maintain 13.5 volts during ECM reprogramming.
• A battery charger set to power supply mode MUST be used during reflash.
• ECU damage may occur if the correct battery charge setting is not used.
3. REFLASH THE ECM
a. Click yes on the Health Check results screen or follow the links above to begin the reflash

• In case reflash failed EVEN ONCE, replace the ECM. (Refer to TIS for instructions on
2ZR-FAE ENGINE CONTROL / ECM or 2ZR-FE ENGINE CONTROL / ECM)
After ECM replacement recheck the calibration ID and perform the reflash if it is NOT
the new calibration ID.
• For general reprogramming procedures, refer to T-SB-0134-16.
• Confirm the latest version of Techstream software is being used.
• If the Techstream does not have sufficient battery power the reflash will fail.
• Confirm the DLC3 cable is in good condition before attempting reflash.
4. ATTACH THE AUTHORIZED VEHICLE MODIFICATION LABEL
a. Fill out the label.
