BODY -
Sunroof
42-79
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.
