ETC Motor
| 1. |
Turn the ignition switch OFF.
|
| 2. |
Disconnect the ETC module connector.
|
| 3. |
Measure resistance between the ETC module terminals 3 and 6.
|
| 4. |
Check that the resistance is within the specification.
|
Specification: 0.3 - 100 [20°C(68°F)]
|
|
| 1. |
Turn the ignition switch OFF and disconnect the battery negative (-)
cable.
|
| 2. |
Remove the resonator and the air intake hose (Refer to “Intake And Exhaust
System” in EM group).
|
| 3. |
Disconnect the ETC module connector (A).
|
| 4. |
Disconnect the coolant hoses (B).
|
| 5. |
Remove the ETC module (C) after loosening the mounting bolts.

Electronic Throttle Control (ETC) Module mounting bolt :
9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)
|
|
| 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 to ETC module directly and
use a lint free cloth moistened by 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)
|
| • |
Install the component with 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, check that the idle speed is stable.
|
If not performing the ETC module learning procedure after replacing
or re-installing, MIL illumination with DTCs might occur.
