CALIBRATION
NOTICE:
-
When the 4WD ECU assembly is replaced, before removing the 4WD ECU assembly, it is necessary to perform ECU Data Save to save the original 4WD ECU assembly information.
-
When the 4WD ECU assembly is replaced, it is necessary to perform the following in order: ECU Configuration and ECU Data Write.
-
When the 4WD linear solenoid (electro magnetic control coupling sub-assembly) is replaced, it is necessary to perform ECU Data Write (when replacing 4WD linear solenoid (electro magnetic control coupling sub-assembly)).
-
When the yaw rate and acceleration sensor (airbag sensor assembly) is replaced, it is necessary to perform ECU Data Initialization.
