Components

Panorama Sunroof Switch Repair procedures

Inspection

1.	Disconnect the negative (-) battery terminal.

2.	Open the sunglass case cover from the overhead console then remove the 2 screws holding the overhead console. Disconnect the switch connector and Map lamp connector, and then remove the overhead console lamp (A).

3.	Check for continuity between the terminals. If the continuity is not as specified, replace the panoramaroof switch.

Panorama Sunroof Motor Repair procedures

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the roof trim assembly. (Refer to Body - "Roof Trim")

3.	Remove the panorama sunroof motor (A) after loosening the screws and disconnecting the connector.

4.	Remove the roller blind motor (A) after loosening the screws and disconnecting the connector.

Sunroof Reset

When One-Touch operation with the switch is activated but the sunroof glass or the roller blind does not move automatically and only moves through manual hold down of the switch, it is because the default setting has been deleted. In such a case, the sunroof must be reset as detailed below.

You need to reset the sunroof motor to its default settings for the following cases :

-	The sunroof motor loses battery power temporarily because the battery or fuse is replaced or the battery has died.

-	The automatic opening or closing of the sunroof, a one-touch feature, does not function properly.

-	The sunroof reopens during automatic closing even if there is no object caught in the sunroof (safety feature)

1.	After IG ON, use CLOSE Switch to fully close the sunroof glass and roller blind.

2.	When the glass and the roller blind is fully closed, release the CLOSE Switch and then press and hold down the switch (about 10 sec.) until the glass and the blind moves slightly one time.

Release the CLOSE Switch and then press and hold down the switch again, and the glass and the blind opens and closes in below order and completes Sunroof Reset process.

Blind slides open > Sunroof glass tilts, slides open, and then closes > Blind slides and closes.

? If the CLOSE Switch is released while above operation is in progress, the reset process is cancelled and you must go back and repeat the process from step 1.

Protecting the Overheated Motor

In order to protect the overheated panoramaroof motor by continuous motor operation, the panoramaroof SCU controls the Run-time and Cool-time of motor as followings;

1.	The panoramaroof SCU (Sunroof Control Unit) detects the Run- time of motor

2.	Motor can be operated continuously for the 1st Run-time(120 ± 10sec.).

3.	Motor which is operated continuously stops operating after the 1st Run-time(120 ± 10sec.).

4.	And then Motor is not operated for the 1st Cool-time(18 ± 2sec.).

5.	Motor is operated for the 2nd Run-time(10 ± 2sec.) at the continued motor operation after 1st Cool-time(18 ± 2sec.)

6.	Motor which is operated continuously stops operating after the 2nd Run-time(10 ± 2sec.)

7.	Motor is not operated for the 2nd Cool-time(18 ± 2sec.).

Motor repeats the 2nd Run-time and 2nd Cool-time at the continued motor operation.

A.	In case that motor is not operated continuously, the Run-time which is limited for protecting the overheated motor is increased.

B.	The Run-Time of motor is initialized to "0" if the battery or fuse is reconnected after being disconnected, discharged or blown.

T1 : 120 ± 10 sec., T2 : 18 ± 2 sec.,

T3 : 10 ± 2 sec., T4 : 18 ± 2 sec.

If the CLOSE Switch is released while above operation is in progress, the reset process is cancelled.

In this case, you have to go back step 1 and restart the Sunroof Reset process.
