SUNROOF SYSTEM

INPUT/OUTPUT SIGNAL CHART

SUNROOF OPERATION

• The sunroof motor assembly operates with a power supply that is output from the BCM while the ignition

switch is ON or retained power is operating.

• The tilt up/down & slide open/close signals from the sunroof switch enable the sunroof motor to move arbi-

trarily.

AUTO OPERATION

The sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof

without 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 the sunroof system to operate

up to 45 seconds after the ignition switch is turned OFF.

Retained power function cancel conditions

• When a front door is opened (door switch ON)

• When ignition switch is turned ON again.

• When 45 seconds elapse on the timer.
