needed for precise fuel injection control.
A performance of emission control and a driveability may effect
when there is a mismatch between the following two values.
• The injector adjustment value stored in ECM
• The injector adjustment value of the injector which is installed on
the vehicle
Injector Adjustment Value Registration must be performed after the
following cases.
• Injector(s) are replaced.
- Injector Adjustment Value Registration for the replaced fuel injector must be performed.
• ECM is replaced.
- Injector Adjustment Value Registration for all the fuel injectors must be performed.
NOTE:
The necessary operation is different depending on the operation result of ECM data save or write. Always
perform the operation according to procedures. Refer to
For injector adjustment value, refer to the following table.
NOTE:
