According to the map light assembly operation, the sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear sub-assembly) operates its built-in motor. Using the map light 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.
If the sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear sub-assembly) is removed and reinstalled or replaced, the sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear sub-assembly) must be initialized.

Before replacing the main body ECU (multiplex network body ECU), refer to Registration.
