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.

THROTTLE VALVE POSITION LEARNING

Description

INFOID:0000000010309022

Throttle valve position learning is an operation to learn the fully closed position of the throttle valve by monitor-
ing the throttle position sensor output signal. It must be performed each time harness connector of electric
throttle control actuator or ECM is disconnected.
• Electric throttle control actuator is removed.
• Electric throttle control actuator is replaced.
• ECM is replaced.

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"

.

Work Procedure

INFOID:0000000010309023

1.

START

1.

Check that accelerator pedal is fully released.

2.

Turn ignition switch ON and wait at least 10 seconds.

3.

Turn ignition switch OFF and wait at least 1 minute.
NOTE:
Check that throttle valve moves by confirming the operating sound.

EXHAUST THROTTLE VALVE POSITION LEARNING

Description

INFOID:0000000010309024

Exhaust throttle valve position learning is an operation to learn the fully closed position of the exhaust throttle
valve. It must be performed each time harness connector of exhaust electric throttle control actuator or ECM is
disconnected.
• Exhaust electric throttle control actuator is removed.
• Exhaust electric throttle control actuator is replaced.
• ECM is replaced.

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"

.

Work Procedure

INFOID:0000000010309025

1.

START

1.

Turn ignition switch ON and wait at least 10 seconds.

2.

Turn ignition switch OFF and wait at least 1 minute.

EGR VOLUME CONTROL VALVE POSITION LEARNING

Description

INFOID:0000000010309026

EGR volume control valve position learning is an operation to learn the fully closed position of the high pres-
sure EGR volume control valve by monitoring the high pressure EGR volume control valve position sensor
output signal. It must be performed under any of the following conditions:
• High pressure EGR volume control valve is removed.
• High pressure EGR volume control valve is replaced.
• ECM is replaced.

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"

.

Work Procedure

INFOID:0000000010309027

1.

START

1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON and wait for 1 minute.
NOTE:
Check that high pressure EGR volume control valve moves by confirming the operating sound.
