Repair procedures

Inspection

The DCT system can be more quickly diagnosed for troubles by using the vehicle diagnostic system (diagnostic tool). (Refer to DTC guide)

diagnostic tool provides the following information.

1)	Self diagnosis : Inspects and displays diagnostic trouble code (DTC)

2)	CAN signals : Checks the system input/output value status

3)	Forced operation : Checks the system operating status

4)	Additional function : Controls system options, zero point adjustment and other functions

Removal

1.	Turn ignition switch OFF and disconnect the battery negative (-) terminal.

2.	Remove the air cleaner assembly and air duct. (Refer to Engine Mechnical System - "Air Cleaner")

3.	Remove the battery and battery tray. (Refer to Engine Electrical System - "Battery")

4.	Remove the ECM. (Refer to Engine Control System - "ECM")

5.	Disconnect the gear actuator connector (A).

Loosen the wiring mounting bolt (A).

Tightening torque :

9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)

Remove the gear actuator assembly after loosening bolts (A).

Tightening torque :

19.6 - 26.5 N.m (2.0 - 2.7 kgf.m, 14.5 - 19.5 lb-ft)

Installation

To install, reverse the removal procedure.

•	Check the details below before installing the gear actuator assembly.

1)	Check that the gear actuator is placed in the "neutral" state.

2)	Check the assembled state of the O-rings (A).

3)	Apply gear oil to the surface of O- rings.

4)	Check the assembled state of the dowel pins.

•	Perform the clutch touch point learning procedure using the diagnostic tool after replacing the clutch actuator assembly.
