Inspection Procedure 2
The motor does not reverse its direction when a load of
140 N or more is applied while the sunroof is closing.
Probable cause
The sunroof-ECU monitors the load conditions from the amount of current flowing
to the motor. If more than the constant amount of current is flowing, the direction
of motor operation is reversed to prevent jamming.
If the motor does not reverse direction even when an excessive load is being applied,
the cause may be a malfunction of the sunroof-ECU.
D
Malfunction of sunroof-ECU
Replace the sunroof-ECU.
Inspection Procedure 3
The timer does not operate for 30 seconds after the
ignition switch is turned to OFF.
Probable cause
The sunroof-ECU has a timer function which operates for 30 seconds after the ignition
switch is turned to OFF. If the timer does not operate, the cause may be a malfunction
of the sunroof-ECU or of the wiring harness or connector.

Inspection Procedure 4
Opening or closing of the sunroof is possible for 30
seconds after turning the ignition switch to OFF, but the
timer function is not extended when the driver’s side door
is opened within this period.
Probable cause
The sunroof timer operation period is extended when an on signal is output from
the driver’s-side door switch. Because of this, if the timer operation period is not
extended, the cause may be a malfunction of the door switch input circuit.

Malfunction of the front door switch (driver’s side)

ON-VEHICLE SERVICE
WATER TEST
Check if there are any leaks in the sunroof by the following
procedure.
1.
Fully close the roof lid glass.
2.
Adjust the water pressure so that water comes out of
the hose to a height of approximately 50 cm when the
hose is held vertically facing upwards.
3.
Hold the end of the hose approximatery 30 cm above
the roof and let the water run onto the weatherstrip for
5 minutes or more.
4.
While doing this, check if any water leaks through into
the passenger compartment from around the roof lid glass.
SUNROOF FIT ADJUSTMENT
1.
Fully close the roof lid glass.
2.
Fully open the sunshade.
3.
Remove the side decoration cover.
4.
To adjust the forward, backward and sideways position
of the roof lid glass, loosen the six roof lid glass assembly
mounting nuts and then adjust the glass forward,
backward or sideways.
NOTE
If the adjustment cannot be made by loosening the
adjustment nuts, the fully closed position of the roof lid
glass may not match that of the motor. If so, adust them
to match their fully closed positions.
5.
To adjust the height of the roof lid glass, loosen the four
guide (A) assembly mounting screws and then move the
roof lid glass assembly along the slot in the guide (A)
assembly.
6.
After adjustment, check to be sure that the sunroof
operates smoothly.
