LOW PRESSURE EGR VOLUME CONTROL VALVE POSITION LEARNING

LOW PRESSURE EGR VOLUME CONTROL VALVE POSITION LEARNING

Description

INFOID:0000000010309028

Low pressure EGR volume control valve position learning is an operation to learn the fully closed position of
the low pressure EGR volume control valve by monitoring the low pressure EGR volume control valve position
sensor output signal. It must be performed under any of the following conditions:
• Low pressure EGR volume control valve is removed.
• Low 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:0000000010309029

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 low pressure EGR volume control valve moves by confirming the operating sound.

INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION LEARNING

Description

INFOID:0000000010309030

Intake manifold runner control valve position learning is an operation to learn the fully closed position of the
intake manifold runner control valve. It must be performed each time harness connector of intake manifold
runner control valve actuator or ECM is disconnected.
• Intake manifold runner control valve is removed.
• Intake manifold runner 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:0000000010309031

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.

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.

Work Procedure

INFOID:0000000010309033

1.

CHECK DTC

1.

Turn ignition switch OFF and wait at least 1 minute.

2.

Turn ignition switch ON.

3.

Check DTC.

Is any DTC detected?

YES

>> Perform trouble diagnosis for detected DTC. Refer to 

EC9-108, "DTC Index"

.

NO

>> GO TO 2.

2.

CHECK ENGINE OIL LEVEL

Refer to 

LU-48, "Inspection"

.

CAUTION:

When the oil level reaches maximum, drain engine oil as to be in MIN and HALF.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Drain or refill engine oil. And then GO TO 3.

3.

PERFORM OK OR NG JUDGEMENT FOR SERVICE REGENERATION

1.

Close the engine hood.

2.

Start engine and warm it up to normal operating temperature.
NOTE:
For best results, warm up the engine until “WATER TEMP” on “DATA MONITOR” mode of “ENGINE”
using CONSULT reaches at least 80

°

C (176

°

F).

3.

Select “PARTICLE FILTER REGENERATION” in “WORK SUPPORT” mode of “ENGINE” using CON-
SULT.

4.

Touch “START”.

Which is displayed on CONSULT screen?

Judged OK>>GO TO 4.
