The repair quality of covered vehicles is extremely important to Toyota. All dealership technicians performing this
LSC are required to successfully complete the most current version of the E-Learning course “Safety Recall and
Service Campaign Essentials”. To ensure that all vehicles have the repair performed correctly; technicians
performing this LSC repair are required to currently hold at least one of the following certification levels:
•
•
•
•

Certified Technician (any specialty)
Expert Technician (any specialty)
Master Technician
Master Diagnostic Technician

It is the dealership’s responsibility to select technicians with the above certification level or greater to perform this
LSC repair. Carefully review your resources, the technician skill level, and ability before assigning technicians to
this repair. It is important to consider technician days off and vacation schedules to ensure there are properly
trained technicians available to perform this repair at all times.

D

The Data Communication Module (DCM) in the subject vehicles are equipped with software to identify the location of
the vehicle using the Global Positioning System (GPS) to support features of the Safety Connect system. Due to
incorrect programming in the DCM software, after November 2nd, 2019, the GPS coordinates for this system will be
calculated incorrectly. This will cause the system to use incorrect vehicle coordinates if one of the system’s features
is activated.

V. PROCEDURE OVERVIEW

CRITICAL INFORMATION

02
2

• You will perform the reprogramming after installing a dedicated CUW application (Special CUW (only for
DCM)) to a Techstream. By using this dedicated CUW application, the reprogramming time can be
shortened.
• The reprogramming takes more than 60 minutes to complete, and the vehicle will turn the IG OFF
automatically when it has passed about 60 minutes with IG ON while the shift lever is in P position.

VI. 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.

be
r1
,2

02
2

STABILIZE THE POWER TO THE TECHSTREAM SIDE
a) Be sure to connect the Techstream to an external AC power supply.
NOTE:
The ECU could be damaged if the battery voltage of the
Techstream drops while reprogramming.

Turn off the screen saver and power saving mode of the
Techstream 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 ECU.

c)

DO NOT block the ventilation opening for the cooling fan of the
Techstream.
NOTE:
If the ventilation opening for the cooling fan is blocked with a
sheet cover or the like, the Techstream may be heated
excessively, causing the operation of the Techstream to stop.
Due to the stop of the operation, the communication for
reprogramming signals could be stopped, resulting in the
damage of the ECU.

VEHICLE PREPERATION
a) Record settings of the audio system, air conditioner, front seats position, etc. since the cable of the negative
battery terminal is going to be disconnected in a later step.

Confirm the following conditions
•
•

•

Vehicle in the IG ON position (engine off).
Turn off all electrical accessories (i.e. audio system, etc.)
Windshield wiper switch in the OFF position.

CONNECT THE 12V BATTERY TO A POWER SUPPLY (GR8/DCA)
a) Connect the GR8/DCA or other type of a power supply (not a battery charger) to the 12V battery.
b) Select the Power Supply Mode from the Charge Menu of the GR8/DCA.
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.

NOTE: A power supply must be connected directly to the 12V battery terminals and NOT the remote
jump posts under the hood (if equipped).

IX. CHECK FOR DTC’S
CONNECT THE TECHSTREAM TO THE VEHICLE
a) Turn the IG OFF.
b) Using a Cable No.1 (provided tool), connect the Techstream to the vehicle.
NOTE: DO NOT use this tool except for this campaign.

Follow the instructions below. Otherwise, the battery voltage will decrease or communication
will become disabled, and this may require the replacement of the DCM.
• Turn off the screen saver and power saving mode of the PC.
• Use the external power supply for the PC. (DO NOT use the PC’s internal battery or vehicle’s battery.)
• Ensure that the communication cable connectors are securely connected, the cable is in
good condition, and the connection is stable.

VERIFY TECHSTREAM SETUP
a) Verify that the Techstream meets the following conditions:
• The software version 14.1 or higher is loaded.
• The Techstream battery is fully charged. If not, connect the Techstream to a 120V 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.

NOTE: If the Techstream communication with the vehicle fails during the re-flash procedure, the
DCM will be damaged.
