6. 6
   The panoramic roof reset procedure is complete.
7. 7
   The sunroof ECU determines the motor operating time.
8. 8
   The motor can operate continuously for the 1st operating time (120 ± 10 sec.).
9. 9
   The motor that operates continuously stops after the 1st operating time (120 ± 10 sec.).
10. 10
    The motor then stays off for the 1st cooling time (18 ± 2 sec.).
11. 11
    The motor operates for the 2nd operating time (10 ± 2 sec.) when continuous motor operation resumes after the 1st cooling time (18 ± 2 sec.).
12. 12
    The motor that operates continuously stops after the 2nd operating time (10 ± 2 sec.).
13. 13
    The motor does not operate for the 2nd cooling time (18 ± 2 sec.).
14. 14
    The motor repeats the 2nd operating time and the 2nd cooling time during continuous motor operation.

    A.	If the motor is not operated continuously, the operating time limit for overheat protection is increased.

    B.	The motor operating time is reset 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.

Overheat Protection To protect the sunroof motor from overheating during continuous operation, the sunroof ECU monitors the motor operating time and cooling time as follows:
