TROUBLESHOOTING

The timer does not operate for 30 seconds after the
ignition switch is turned to LOCK (OFF) position. (When
the ignition switch is turned on, the sunroof operates.)

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 ETACS-ECU, sunroof-ECU or of the wiring
harness or connector.
