ETC Motor
1.
Turn the ignition switch OFF.
2.
Disconnect the ETC module connector.
3.
Measure resistance between the ETC module terminals 1 and 2.
4.
Check that the resistance is within the specification.
Specification: 0.3 ~ 100 Ω [20°C(68°F)]
Removal
1.
Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
2.
Remove the air intake hose (A) after disconnect the hose and clamp.
3.
Disconnect the ETC module connector (A).
4.
Disconnect the coolant hoses (B).
5.
Remove the installation bolts, and then remove the ETC module (A) from the engine.
Cleaning
1.
Remove the ETC Module.
(Refer to Engine Control System - "ETC System")
2.
Keep the ETC module plate (A) as open status.
3.
Clean the pollutant in the throttle body with a soft cloth moistened by cleaning fluid.
•
Do not spray cleaning fluid directly onto ETC module and use a lint free cloth moistened with cleaning fluid.
•
Be careful not to clean the coating fluid around the shaft.
If coating fluid is removed, idling control failure might occur by
foreign substance inflow or excessive air leakage.
4.
After cleaning, re-install the ETC module and then perform the ETC module learning procedure.
(Refer to Engine Control System - "ETC System" - Adjustment)
Installation
•
Install the component to the specified torques.
•
Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
1.
Install in the reverse order of removal.

ETC module learning procedure
Be sure to perform the ETC module learning procedure when replacing or re-installing the ETC module.
1.
Wait for 1 minute with the ignition switch ON.
2.
Start the engine and hold the idle status for 15 minutes.
3.
Waif for 1 minute with the ignition switch OFF.
4.
Restart the engine checking that the idle speed is stable.
The ETC module learning procedure must be performed after
replacing or re-installing ETC. The ECM will set DTC''s and illuminate
the MIL.
