PANORAMIC MOON ROOF SYSTEM Key-off Operation Function Operates even if Operating Conditions are not Satisfied

DESCRIPTION

According to the panoramic moon roof switch (roof console box sub-assembly) operation, the sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear assembly) operates its built-in motor. Using the panoramic moon roof switch (roof console box sub-assembly), if the sliding roof glass or roof sunshade can be operated normally when 45 seconds or more have elapsed since the ignition switch was turned off, the key-off operation function may be abnormal.

CAUTION / NOTICE / HINT

Note


  • If the sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear assembly) is removed and reinstalled or replaced, the sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear assembly) must be initialized.
