stops (to wipe-out the memory of lid position and operating friction).

2.

Initialization of system should be conducted after the following conditions.
• When the battery has been disconnected or discharged.
• When the sunroof motor has been disconnected from power.
• When the sunroof motor is changed.
• When the sunroof does not operate normally (Incomplete initialization conditions).

automatically fully closed. Keep pushing the switch during this operation. Release the switch when the
operation is complete.

4.

Push and hold the tilt up switch within 10 seconds of step 3.

SUNROOF

System Description

INFOID:0000000001724559

SUNROOF SYSTEM

INPUT/OUTPUT SIGNAL CHART

SUNROOF OPERATION

• The sunroof motor assembly is supplied with constant battery power. The BCM supplies power while the

ignition switch is ON or retained power is operating.

• The open & close signals from the sunroof switch enable the sunroof motor to move arbitrarily.

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.

ANTI-PINCH FUNCTION

The CPU (central processing unit) of the sunroof motor assembly monitors the sunroof motor operatin and the
sunroof position (fully-closed or other) by signals from the sunroof motor.
When the sunroof motor detects an interruption during the slide close or tilt down operation, the sunroof motor
assembly will reverse to slide open or tilt up.
