Are both data identical?
YES
▶
Go to "Verification of Vehicle Repair".
NO
▶
If error is not corrected after reperforming "INJECTOR CORRECTION" procedure, replace ECM.
NOTE
Input IQA data of injector mounted at cylinder at replacing ECM using scantool.
If this process is not performed, engine check lamp on cluster blinks and normal engine power generation is impos-
sible.
VERIFICATION OF VEHICLE REPAIR
EF565CD3
After a repair, it is essential to verify that the fault is corrected.
1.
After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.
2.
Clear recorded DTC using Scantool.
3.
Drive the vehicle within DTC "Enable conditions" in "General information".
4.
After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.
5.
Are any DTCs recorded ?

DTC P2009 INTAKE MANIFOLD RUNNER CONTROL CIRCUIT LOW(BANK 1)
COMPONENT LOCATION

Variable Swirl Control Actuater
SCMFL6509L
GENERAL DESCRIPTION
E6F57131
Variable swirl control actuator consists of DC motor and motor position sensor(potentiometer) which detects the position
of swirl valve.As closing one intake port out of two at idle and below 3000RPM, swirl effect is taken on intake air. This
swirl effect increases air flow rate.
However, because air flow rate is too high, swirl effect is neglectable thus, swirl valve is opened for efficiency of intake air.
To prevent swirl valve and shaft form being stuck by foreign metarial, and to learn max opening and closing position of
swirl valve, it is fully opened and closed twice at turning engine OFF.
※
Swirl
The air flow which indicates Intake air swirls with respect to the axis passing through the centre of piston with length-
direction by intake port which is eccentric from the centre of combustion chamber.
DTC DESCRIPTION
E52AFD3E
P2009 is set when 1) short to ground in variable swirl actuator driving motor (+) or (-) output terminal. or 2) tiny open in
motor (-) output terminal for a long period occurs.The polarity of (+) and (-) lines shift each other in accordance with the
condition of swirl valve(opened or closed) thus, checking both (+) and (-) circuits is required.
