MOONROOF SYSTEM

INPUT/OUTPUT SIGNAL CHART

MOONROOF OPERATION

• Moonroof 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 moonroof switch enables moonroof motor to move arbitrarily.

• Moonroof motor assembly receives a vehicle speed signal from combination meter and controls the moon-

roof motor torque of tilt-down at the time of high speed operation.

AUTO OPERATION

Moonroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the moonroof

without holding the moonroof 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 moonroof system to oper-

ate during the first 45 seconds that the ignition switch is cycled from the ON position to the OFF position.

Retained power function cancel conditions

• Front door CLOSE (door switch OFF)

→OPEN (door switch ON).

< SYSTEM DESCRIPTION >

SYSTEM

• When ignition switch is ON again.

• When timer time passes. (45 seconds)

ANTI-PINCH FUNCTION

The CPU of moonroof motor assembly monitors the moonroof motor operation and the moonroof position

(fully-closed or other) by the signals from moonroof motor.

When moonroof motor detects an interruption during the following slide close and tilt down operation, moon-

roof switch controls the motor for open and the moonroof will operate until full up position (when tilt down oper-

ates) or 100 mm (3.94 in) or more in an open direction (when slide close operates):

• Close operation and tilt down when ignition switch is in the “ON” position
