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 during 30 seconds after the
ignition switch is turned to LOCK (OFF) position.
Probable cause
The sunroof-ECU has a timer function which operates during 30 seconds after the
ignition switch is turned to LOCK (OFF) position. 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 immediately
after turning the ignition switch to LOCK (OFF) position,
but the timer function does not operate continuously for
another 30 seconds if the driver's side door is opened
within 30 seconds.
Probable cause
The operation period for the sunroof timer 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.
D Malfunction of wiring harness or connector
D Malfunction of driver's door switch
D Malfunction of sunroof-ECU
Check the driver's door switch continu-
ity. (Refer to P.42-22.)
