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.
3
•• PROTECTED 関係者外秘
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 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.
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 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 ECU.
VI.
CIRCUMFERENCE MONITORING CAMERA CONTROL MODULE SYSTEM CALIBRATION ID VERIFICATION
1.
CHECK FOR DTC’S
a)
Using a GTS+, click the “Health Check” button on the Main Menu.
NOTE:
This Campaign covers only the software update to the Circumference Monitoring Camera Control Module System, as detailed in these instructions. It does not cover the diagnosis or replacement of any other systems on the vehicle.

•• PROTECTED 関係者外秘
b)
When the vehicle has no “OFF position” in the light control switch:
•
Turn the IG ON.
•
Set the light control switch to the AUTO position and make sure that the exterior lights are turned on.
•
Light up the automatic light control sensor with work light to keep the exterior lights turned off.
2.
STOP THE OPERATION OF THE ELECTRIC FAN (For HV Model)
a)
Disconnect the electrical connector from the cooling fan on the radiator fan shroud.
If the cooling fans run during the Calibration update procedure, the battery voltage will be inconsistent and could cause damage to the control module(s).
NOTE:
The illustration is an example of ES.
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 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.
NOTE:
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 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.
NOTE:
If the GTS+ communication with the vehicle fails during the re-flash procedure, the parking assist ECU will be damaged.
VIII.
