SUNROOF
System DescriptionINFOID:0000000006141225
SUNROOF SYSTEM
 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 s witch enables operate sunroof motor to move arbi-
trarily.
 Sunroof motor assembly receives a vehicle speed signal from combination meter and controls the sunroof motor 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 dur-
ing 45 seconds even when 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
The CPU of sunroof motor assembly monitors the s unroof 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 the sunroof will operate until full up position (when tilt down operate) or
150 mm (5.91 in) or more in an open direction (when slide close operate):
