SYSTEM OUTLINE
Current is applied at all times through the POWER fuse to TERMINAL 5 of the power relay. With the ignition SW turned on,
the current flows through the GAUGE fuse to TERMINAL 7 of the integration relay to TERMINAL (A) 24 to TERMINAL 1 of
the power relay to TERMINAL 2 to GROUND, as a result, the power relay is activated and the current to TERMINAL 5 of the
power relay flows from TERMINAL 3 to TERMINAL 4 of the moon roof control SW and relay.
1. SLIDE OPEN OPERATION
Only when the slide open switch is valid and actuated, the moon roof motor will operate continually towards the open
direction of the roof panel.
Releasing and depressing again the open switch, or depressing another operation switch shall cancel this express open
function. The relay shall operate the moon roof motor continually for only approx. 20 seconds per actuation.
2. SLIDE CLOSE OPERATION
Only when the tilt up switch is valid and actuated, the moon roof motor will operate towards the close direction of the roof
panel.
When the moon roof reaches half position, the limit switch no. 1 is turned from on to off. Thereby signaling the moon roof
control relay to stop the motor. The motor can not continue operation until the close switch is released and depressed again.
3. TILT UP OPERATION
Only when the tilt up switch is valid and actuated, the moon roof motor will operate towards the closed direction of the roof
panel.
4. TILT DOWN OPERATION
Only when the slide open switch is valid and actuated, the moon roof motor will operate towards the open direction of the
roof panel.
5. KEY OFF MOON ROOF OPERATION
With the ignition SW turned from on to off, the integration relay operates and the current flows from the DOOR fuse to
TERMINAL (A) 15 of the integration relay to TERMINAL (A) 24 to TERMINAL 1 of the power relay to TERMINAL 2 to
GROUND for about 43 seconds. In the same way as normal operation, the current flows from the POWER fuse to
TERMINAL 5 of the power relay to TERMINAL 3 to TERMINAL 4 of the moon roof control SW and relay. As a result, this
relay is still activated for about 43 seconds after the ignition SW is turned off, allowing the open/close operation of the moon
roof. Also, by opening the front door (Door open detection SW on) within about 43 seconds after turning the ignition SW to
off, a signal is input to TERMINAL 6 or 4 of the integration relay. As a result, the relay turns off and open/close movement of
the moon roof stops.
