MOONROOF SYSTEM

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

AUTO OPERATION

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

NOTE:

If initialization setting is not performed, the automatic function does not operate.

During automatic operation, when the moonroof switch assembly is operated, automatic operation can be stopped.

RETAINED POWER FUNCTION

Retained power operation is an additional power supply function that enables moonroof system to operate for 45 seconds after ignition switch is placed 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

Moonroof motor assembly, sunshade motor assembly and BCM transmit and receive signal via LIN communication.

ANTI-PINCH FUNCTION

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