Removal
1. Remove the rear door finisher. Refer to EI-31.
2. Temporarily reconnect the power window switch.
3. Operate the power window switch to raise/lower the door win-
dow until the glass bolts can be seen.
4. Partially remove the inside seal.
5. Remove the glass run from the partition glass.
6. Remove the partition sash bolt (lower) and screw (upper) to
remove the sash.
7. Remove the glass bolts and glass.
Installation
Installation is in the reverse order of removal.
• Reset the power window limit switch.
Fitting Inspection
• Check that the glass is securely fit into the glass run groove.
• Lower the glass slightly [approximately 10 to 20 mm (0.39 to 0.79 in)], and check that the clearance to the
sash is parallel. If the clearance between the glass and sash is not parallel, loosen the regulator bolts, guide
rail bolts, and glass and carrier plate bolts to correct the glass position.

TILT DOWN OPERATION
When the tilt switch is operated for tilt down, ground is supplied
• to sunroof motor assembly terminal 10
• through sunroof switch terminal 6
• through sunroof switch terminal 2
• through sunroof motor assembly terminal 8
• through grounds M57, M61 and M79.

• to sunroof motor assembly terminal 9
• through sunroof switch terminal 3
• through sunroof switch terminal 2
• through sunroof motor assembly terminal 8
• through grounds M57, M61 and M79.

RETAINED POWER OPERATION
When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to RF-14, "
CONSULT-II Function (BCM)".
MEMORY RESET PROCEDURE
To reset the sunroof motor memory from any sunroof position (full open, partially open, closed, partially
vented, and vented), push and hold the sunroof tilt switch in the forward (DOWN) position until the sunroof is
fully closed. After it has closed all the way, push and hold the tilt switch forward (DOWN) for more than 2 sec-
onds to re-establish the motor preset position. The sunroof should now operate normally.
INTERRUPTION DETECTION FUNCTION
The CPU (central processing unit) monitors the sunroof motor operation and the sunroof position (fully-closed
or other) by the signals from the sunroof motor.
When sunroof motor detects an interruption during the following sliding close operations, sunroof switch con-
trols the motor for open and the sunroof will operate until it reaches full open position.
• automatic close operation when ignition switch is in the ON position.
• automatic close operation during retained power operation.
