Injector Drive Circuit

To increase the responsiveness of the injector, the

voltage that drives the injector is raised to a high voltage,

accelerating  the  magnetization  of  the  solenoid  and

increasing the responsiveness of the TWV.

The  battery  voltage  is  raised  to  about  110  V  by  a

high-voltage generating circuit inside the ECU and that

voltage is supplied to the injector to actuate it.

Injector QR/ID Codes

Injectors are processed to exacting tolerances, but

there are minute variations in the amount they inject, so

to  correct  for  these  variations,  a  correction  volume  is

recorded on the QR/ID codes of the injectors.

During  manufacture,  the  QR  code  is  read  by  a

scanner  and  the  correction  value  is  registered  in  the

ECU.

IMPORTANT

• In order for the engine ECU to recognize and

calibrate injectors, if an injector or the engine
ECU is replaced, perform "Injector calibration"
using a diagnostics tool.

When Replacing an Injector

Register the ID code of the replacement injector into

the ECU.

9Y1210824ENM0026US0

When Replacing the Engine ECU

Register the ID codes of all of the injectors into the

replacement engine ECU.

When replacing an ECU, as it is necessary to write

all  of  the  data,  including  the  injector  corrections,  only

KUBOTA can write the data to the ECU.
