after it is raised a little higher than the maximum TILT
position.
When this is complete, the sunroof system is

PROTECTING THE OVERHEATED MOTOR
In order to protect the
overheated sunroof motor by continuous motor operation, the sunroof ECU
controls the Run-time and Cool-time of motor as followings;
| 1. |
The Sunroof ECU 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.). |
| 8. |
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. |
