INJECTOR ADJUSTMENT VALUE REGISTRATION

Description

INFOID:0000000010309020

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 

EC9-144, "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:0000000010309021

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.

SERVICE REGENERATION

SERVICE REGENERATION

Description

INFOID:0000000010309032

Certain types of driving conditions (e.g. urban driving) may load to heavy loads in DPF (Diesel Particulate Fil-
ter). This soot mass may adversely affect the driving. This function can perform DPF regeneration under vehi-
cle stop condition.
Service regeneration is performed with CONSULT to reduce particulate matter in DPF (Diesel Particulate Fil-
ter). Service regeneration should be performed in the following cases.
• ECM enters fail-safe mode because the amount of particulate matter in DPF reaches the specified level.

NOTE:
When ECM enters fail-safe mode because the amount of particulate matter in DPF reaches the specified
level, check whether or not DTC P2002 is stored in ECM. In the case of DTC stored, perform the Diagnostic
Procedure for the DTC.

• ECM is replaced.

NOTE:
• Based on the signal from sensors ECM measures the amount of particulate matter in DPF and stores the

value in EEPROM (Electrically Erasable Programmable Read Only Memory). When ECM is replaced as
new one, there is a difference between the actual amount of particulate matter and the value stored in new
ECM, because the value stored in new ECM is initialized one. In the case above, ECM can not perform
regeneration control correctly. So, perform service regeneration to make the amount of particulate matter
in DPF zero.

• 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 

EC9-144, "Work Procedure"

.

• Component inspection for DPF is performed.

CAUTION:

Oil change is required, depending on service regeneration procedure. Because fuel mixes with
engine oil during service regeneration. The mixture does not occur during the regeneration which is
automatically performed under normal operation.

DIESEL PARTICULATE FILTER DATA CLEAR

Description

INFOID:0000000010309034

Perform “DPF DATA CLEAR” in “WORK SUPPORT” mode with CONSULT when oxidation catalyst with diesel
particulate filter is replaced with a new one. Based on the signal from sensors, ECM estimates the amount of
particulate matter in diesel particulate filter and stores the value in EEPROM as diesel particulate filter data.
When oxidation catalyst with diesel particulate filter is replaced with a new one, there is a difference between
diesel particulate filter data stored in ECM and the actual amount of particulate matter in diesel particulate fil-
ter, because no particulate matter is trapped in new diesel particulate filter. In this case, ECM cannot perform
regeneration control correctly. So perform “AFTER DPF REPLACEMENT” in “WORK SUPPORT” mode of
“ENGINE” using CONSULT to clear diesel particulate filter data stored in ECM.

CAUTION:

Never perform “AFTER DPF REPLACEMENT” in “WORK SUPPORT” mode of “ENGINE” using CON-
SULT when oxidation catalyst with diesel particulate filter is not replaced with a new one. Diesel partic-
ulate filter may be damaged because regeneration is not performed at appropriate timing.
