Sun Roof

General Description

The circuit consists of sun roof switch, sun roof
control unit, safety stop switch, limit switch and sun
roof motor.
When sun roof switch is turned on, battery voltage is
applied to sun roof control unit through circuit breaker
and power window relay.
Accordingly, when sun roof switch is set to “Open” or
“Close” position, open or close relay incorporated
into the control unit is activated to change rotational
direction of sun roof motor to open or close sun roof.
Also, operational process (full close 

→

limit stop 

→

full open 

→

safety stop 

→

full close) of sun roof is

controlled by the control unit in accordance with
signals received from safety stop switch and limit
switch.
