1.

IG "OFF" and disconnect the air hose between throttle body and air mass flow sensor.

2.

Check stuck on throttle valve..

3.

Is the throttle valve normal?

	▶ Go to "Check ETC motor resistance" as follows.
	▶ Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.

4.

IG "OFF" and disconnect ETC Motor & TPS connector.

5.

Measure the resistance between ETC motor(+) and (-) terminals of ETC Motor & TPS connector (component side).

Specification : Approx. 1.275 ~ 1.725Ω @ 23℃(73.4℉)

6.

Is the throttle valve normal?

	▶ Is the measured resistance within specification ?
	▶ Substitute with a known - good ETC motor and check for proper operation. If the problem is corrected, replace ETC motor and go to "Verification of Vehicle Repair" procedure.

※ Procedure of ETS Initialization

1)

Erase the trouble codes on ECM

2)

Turn the ignition key off and keep this condition until the main relay is turned off.(It will take 10sec.)

3)

Turn ignition key on more than 1second to record the throttle motor position on the EEPROM

7.

IG "OFF" and connect ETC Motor & TPS connector.

8.

After IG "ON", execute the "ETC motor actuation test" by Scantool.

9.

Is the measured resistance within specification ?

	▶ Substitute with a known - good ECM and check for proper operation. If the problem is corrected, replace ECM and go to "Verification of Vehicle Repair" procedure. note There is a memory reset function on scantool that can erase optional parts automaticallydetected and memorized by ECM. Before or after testing ECM on the vehicle, use this function to reuse the ECM on the others
	▶ Substitute with a known - good ETC motor and check for proper operation. If the problem is corrected, replace ETC motor and go to "Verification of Vehicle Repair" procedure.
