• 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 & slide open/close signals from sunroof switch enables operate sunroof motor to move arbi-
trarily.
• Sunroof motor assembly receives a vehicle speed signal from unified meter and A/C amp. and controls the
sunroof motor torque of tilt-down 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.

The CPU of sunroof motor assembly monitors the sunroof motor operation and the sunroof position (fully-
closed or other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open. And then the sunroof will operate until full up position (when tilt down oper-
ate) or 150 mm (5.91 in) or more in an open direction (when slide close operate):
• close operation and tilt down when ignition switch is in the “ON” position
