SUNROOF SYSTEM

The sunroof motor assembly receives the signal from the sunroof switch assembly to operate the sunroof, and transmits the signal from the sunroof switch assembly to the sunshade motor assembly via communication line.
The sunshade motor assembly operates the sunshade with the operate signal received from the sunroof switch assembly or the communication line received from the sunroof motor assembly.

AUTO OPERATION

The sunroof and sunshade operates automatically by operating the sunroof switch assembly.

note	If initialization setting is not performed, the automatic function does not operate. During automatic operation, when the sunroof switch assembly is operated, automatic operation can be stopped.

RETAINED POWER FUNCTION

Retained power operation is an additional power supply function that enables sunroof system to operate for 45 seconds after ignition switch is turned OFF.

RETAINED POWER FUNCTION CANCEL CONDITIONS

Any of the following conditions is satisfied.

Front door CLOSE (door switch OFF)→OPEN (door switch ON)
When ignition switch is ON again.
When timer time passes. (45 seconds)

LIN COMMUNICATION

Sunroof motor assembly, sunshade motor assembly and BCM transmit and receive signal by LIN communication.

ANTI-PINCH FUNCTION

The sunroof motor assembly monitors the sunroof condition using the signals from sunroof motor. When sunroof motor assembly detects an interruption during auto operation (close or tilt down operation), sunroof motor will tilt up or open [150 mm (5.91 in) or more] sunroof.
The sunshade motor assembly monitors the sunshade condition using the signals from sunshade motor. When sunshade motor assembly detects an interruption during auto close operation, sunshade motor will open [150 mm (5.91 in) or more] sunshade.

caution

There are some small distances immediately before the closed position which cannot be detected.

note	If initialization setting is not performed, the anti-pinch function does not operate. When the distance between pinching position and fully-open position is less than 150 mm (5.91 in), sunroof or sunshade reverses to fully-open position.
