Sunroof / Moonroof: Description and Operation

The circuit consists of the starter switch, sun roof switch, sun roof control unit, safety stop switch, limit switch, and sun roof motor.

When the sun roof switch is turned on, the battery voltage is applied to the sun roof control unit through the circuit breaker and the power window relay on the circuit. Accordingly, when the sun roof switch is set to Open or Close position, the open or close relay incorporated into the control unit is activated to change the rotational direction of the sun roof motor to open or close the sun roof.

Also, the operational process (full close> limit stop > full open > safety stop> full close) of the sun roof is controlled by the control unit in accordance with signals received from the safety stop switch and limit switch.
