SUNROOF OPERATION
• Sunroof motor assembly operates with the power supply that is output from BCM while ignition switch is ON
or retained power is operating.
• Tilt up/down and slide open/close signals from sunroof switch activates the sunroof motor to move arbitrarily.
• Sunroof motor assembly receives a vehicle speed signal from unified meter and A/C amp. and controls the
sunroof motor torque at the time of high speed operation.
AUTO OPERATION
Sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof with-
out holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.
RETAINED POWER OPERATION
Retained power operation is an additional power supply function that enables sunroof system to operate 45
seconds even after the ignition switch is turned OFF.
RETAINED POWER FUNCTION CANCEL CONDITIONS
• Front door CLOSE (door switch OFF)
→
OPEN (door switch ON).
• When ignition switch is ON again.
• When timer time passes. (45 seconds)
ANTI-PINCH FUNCTION
CAUTION:
There are some small distances immediately before the closed position that cannot detected.
The CPU of sunroof motor assembly monitors the sunroof condition by the signals from sunroof motor. When
sunroof motor assembly detects an interruption during close or tilt down operation, sunroof motor tilts up or
open [150 mm (5.91 in) or more] sunroof.
