SYSTEM OUTLINE

CURRENT ALWAYS FLOWS TO TERMINAL 4 OF THE POWER MAIN RELAY THROUGH THE POWER FUSE, WITH THE IGNITION SW
TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 2 OF THE POWER MAIN RELAY. THIS ACTIVATES THE
RELAY AND CURRENT FLOWING TO TERMINAL 4 OF THE POWER MAIN RELAY FLOWS TO TERMINAL 1 OF THE POWER MAIN RELAY
TO TERMINAL 6 OF THE SUN ROOF CONTROL RELAY.
1.
SLIDE OPEN OPERATION
WHEN THE IGNITION SW IS ON AND THE SUN ROOF SW IS PUSHED TO THE OPEN SIDE, A SIGNAL IS INPUT TO TERMINAL 8 OF THE
SUN ROOF CONTROL RELAY. WHEN THIS OCCURS ACTIVATING THE RELAY SO THAT CURRENT FLOWS FROM TERMINAL 6 OF THE
RELAY TERMINAL 5
TERMINAL 12 GROUND, THE MOTOR ROTATES TO THE OPEN SIDE AND THE SUN ROOF SLIDES OPEN AS LONG AS THE SUN
ROOF CONTROL SW IS PUSHED TO THE OPEN SIDE.
WHEN THE SUN ROOF IS OPENED COMPLETELY, EVEN IF THE SUN ROOF SW IS PUSHED CONTINUOUSLY, THE CURRENT TO THE
SUN ROOF MOTOR INCREASES.
IN THIS CASE, THE CIRCUIT BREAKER BUILT INTO THE MOTOR OPENS AND CUTS OUT THE CURRENT TO THE MOTOR,
PREVENTING THE MOTOR FROM BURNING OUT.
2.
SLIDE CLOSE OPERATION
WHEN THE IGNITION SW IS ON AND THE SUN ROOF CONTROL SW IS PUSHED TO THE CLOSE SIDE, A SIGNAL IS INPUT TO
TERMINAL 7 OF THE SUN ROOF CONTROL RELAY. THIS ACTIVATES THE RELAY AND THE CURRENT FLOWING TO TERMINAL 6
FLOWS TO TERMINAL 1
TERMINAL 12 GROUND. THIS CAUSES THE MOTOR TO ROTATE TO THE CLOSE SIDE AND SLIDE CLOSE OPERATION CONTINUES
AS LONG AS THE SUN ROOF CONTROL SW IS PUSHED TO THE CLOSE SIDE.
100 MM BEFORE THE FULLY CLOSED POSITION THE SUN ROOF LIMIT NO. 1 SW TURN OFF. THIS SIGNAL IS INPUT INTO THE RELAY,
SO THE RELAY STOPS OPERATION. THUS CURRENT DOES NOT FLOW TO THE SUN ROOF MOTOR AND THE SUN ROOF
AUTOMATICALLY STOPS.
IF THE SUN ROOF SW IS THEN PUSH AGAIN, THE TIMER INSTALLED IN THE SUN ROOF CONTROL TURNS ON AND THE RELAY
OPERATES FOR 0.65 SEC. TO RE–OPERATE THE MOTOR SO THAT THE SUN ROOF LIMIT SW NO. 1 TURNS ON (SUN ROOF LIMIT SW
NO. 2 TURNS OFF). AS A RESULT, AS LONG AS THE SUN ROOF SW IS PUSHED, SLIDE CLOSE OPERATION OCCURS AND THE SUN
ROOF IS ABLE TO FULLY CLOSE.
3.
TILT UP OPERATION
WHEN THE SUN ROOF CONTROL SW IS PUSHED TO THE TILT UP POSITION, WITH THE IGNITION SW TURNED ON AND THE SLIDE
ROOF COMPLETELY CLOSED A SIGNAL IS INPUT TO TERMINAL 2 OF THE SUN ROOF CONTROL RELAY AND SUN ROOF LIMIT SW
NO. 2 IS TURNED OFF (SUN ROOF LIMIT SW NO. 1 TURNS ON) SIMULTANEOUSLY, CAUSING THE SUN ROOF CONTROL RELAY TO
OPERATE. AS A RESULT, THE RELAY IS ACTIVATED AND CURRENT FLOWS FROM TERMINAL 6 OF THE RELAY
TERMINAL 3 OF THE SUN ROOF MOTOR
ROTATING THE MOTOR FOR TILT UP OPERATION.
4.
TILT DOWN OPERATION
WHEN THE SUN ROOF CONTROL SW IS PUSHED TO THE TILT DOWN POSITION, WITH THE IGNITION SW TURNED ON AND THE
SLIDE ROOF TILTED UP, A SIGNAL IS INPUT TO TERMINAL 9 OF THE SUN ROOF CONTROL RELAY SIGNALS THAT SUN ROOF LIMIT
SW NO. 1 AND NO. 2 ARE OFF ARE INPUT SEPARATELY TO TERMINAL 10 AND TERMINAL 4.
AS A RESULT, RELAY ACTIVATES AND THE CURRENT FLOWS FROM TERMINAL 6 OF THE RELAY
THE SUN ROOF MOTOR
MOTOR FOR TILT DOWN OPERATION.
