Sunroof / Moonroof: Description and Operation

SUNROOF

System Description

OUTLINE
Electric sunroof system consists of
- Sunroof switch
- Sunroof motor assembly
- BCM (body control module)

BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.

OPERATION
Sunroof can be opened or closed and tilted up or down with sunroof switch.

RETAINED POWER OPERATION
When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 seconds
- to sunroof motor assembly terminal 5
- through BCM terminal 53.

When power is supplied, the sunroof can be operated.

The retained power operation is canceled when the driver or passenger side door is opened.

RAP signal period can be changed by CONSULT-II. Refer to "CONSULT-II Function (BCM)".

MEMORY RESET PROCEDURE
If the battery is disconnected or the sunroof motor harness connector is disconnected, the slide switch will become inoperable and the sunroof motor memory must be reset. To reset the sunroof motor memory from any sunroof position (full open, partially open, closed, partially vented, and vented), repeatedly push the sunroof tilt switch to the forward (CLOSE) position until the sunroof is fully closed. Finally, push and hold the tilt switch forward (CLOSE) for more than 2 seconds to re-establish the motor preset position. The sunroof should now operate normally.

INTERRUPTION DETECTION FUNCTION
The CPU (central processing unit) of sunroof motor 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 sliding close operation, sunroof switch controls the motor for open and the sunroof will operate until it reaches full open position.
- automatic close operation when ignition switch is in the ON position
- automatic close operation during retained power operation.

INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to normal.
1. If the sunroof is open, push and hold the tilting switch toward the tilt down position until the lid is fully closed. If the sunroof is already closed, perform step 2.
2. Push the tilting switch toward the tilt up position for more than 1 second.
