DELAYED POWER OPERATION

When the ignition switch is turned to OFF position from ON or START position, power is supplied for approxi-
mately 45 seconds

●

to sunroof motor assembly terminal 6

●

from BCM terminal 135.

Then the electrical sunroof can be operated.
The retained power operation is canceled when the driver or passenger side door is opened.

ANTI – PINCH SYSTEM

The CPU of sunroof motor monitors the sunroof motor operation and the sunroof position (full closed or other)
by the signals from sunroof motor. When sunroof motor detects interruption during the following close opera-
tion, sunroof switch controls the motor for open and the sunroof will operate about 150 mm (5.91 in).
The operation condition is the following

●

●

automatic close operation during retained power operation.
