INJECTOR ADJUSTMENT VALUE REGISTRATION

Description

INFOID:0000000010935599

Injector adjustment value indicates manufacturing tolerance and the
value is printed on the top of fuel injector.
The injector adjustment value which is correctly stored in ECM is
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 

EC-944, "Work Procedure"

.

For injector adjustment value, refer to the following table.
NOTE:
“J” and “Q”, “9” and “0 (zero)” are not applied.

Work Procedure

INFOID:0000000010935600

1.

START

NOTE:
• Before performing this procedure, record injector adjustment value printed on a fuel injector.
1.

Turn ignition switch ON (engine stopped).

2.

Select “ENTER INJECTOR CODES” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.

3.

Touch “START”.
NOTE:
When touching “START”, CONSULT reads injector adjustment values stored in ECM.

4.

Select the number of the cylinder which needs Injector Adjustment Value Registration.

5.

Input injector adjustment value.
NOTE:
• For injector adjustment value, refer to the following table.

INJECTOR ADJUSTMENT VALUE REGISTRATION

•  “J” and “Q”, “9” and “0 (zero)” are not applied.

6.

Repeat step 4 - 5 till there is no cylinder which needs Injector Adjustment Value Registration, and touch
“START”.
NOTE:
When touching “START”, injector adjustment values stored in CONSULT are written onto ECM memory.

7.

Check that the following values are same for each cylinder.

-

Injector adjustment value which is printed on a fuel injector.

-

Injector adjustment value which is displayed on CONSULT screen.

NOTE:
•

In this step, CONSULT reads injector adjustment values stored in ECM and displays the values on the
CONSULT screen. This is for checking if injector adjustment values are written onto ECM memory cor-
rectly.

•

If DTC is detected, perform DTC Confirmation Procedure for the DTC, and check if the same DTC is
detected again.

8.

Turn ignition switch OFF and wait at least 1 minute.
