IV. 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.
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.
V. CALIBRATION ID VERIFICATION
1.
CHECK FOR DTC’S
a) Using a Techstream, perform a Health Check to check for any
Diagnostic Trouble Codes.
NOTE:
This Campaign covers only the software update to the DCM, as
detailed in these instructions. It does not cover the diagnosis or
replacement of any other systems on the vehicle.
