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.

AUTO OPERATION
The power sunroof AUTO feature makes it possible to open and close the sunroof without holding the sunroof switch in the down or up position.

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.
- from BCM terminal 29.

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".

MEMORY RESET PROCEDURE
If the battery is disconnected, or the sunroof motor harness connector is disconnected, 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), push and hold the sunroof switch in the forward (CLOSE) position until the sunroof vent is in the full-up position. This resets the sunroof motor memory and now the sunroof will operate correctly.

INTERRUPTION DETECTION FUNCTION

When sunroof motor detects an interruption during the sliding close operation, sunroof switch controls the motor for open and the sunroof will operate until full open position.
