• to sunroof motor assembly terminal 1
• through sunroof switch terminal 3
• through sunroof switch terminal 2
• through grounds M57 and M61.
Then the sunroof will tilt up/slide closed.
TILT DOWN/SLIDE OPEN OPERATION
When down/open switch is pressed, ground is supplied
• to sunroof motor assembly terminal 5
• through sunroof switch terminal 1
• through sunroof switch terminal 2
• through grounds M57 and M61.
Then the sunroof will tilt down/slide open.
AUTO OPERATION
The power sunroof AUTO feature makes it possible to slide open and slide closed or tilt up and tilt down the
sunroof without holding the sunroof switch in the UP/CLOSE or DOWN/OPEN position.
RETAINED POWER OPERATION
When the ignition switch is turned to OFF position from ON position, power is supplied for 45 seconds
• through BCM terminal 68
• to sunroof motor assembly terminal 9.
When power is supplied, the sunroof can be operated.
The retained power operation is canceled when the front door LH or RH is opened.
RAP signal period can be changed by CONSULT-III. Refer to RF-16, "
Work Support" .
ANTI-PINCH FUNCTION
The CPU (central processing unit) of sunroof motor assembly monitors the sunroof motor operation and the
sunroof position (fully-closed or other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until it reaches full up position (during tilt down
operation) or 125 mm (4.92 in) or more in an open direction (during slide close operation).
• close operation and tilt down when ignition switch is in the ON position.
• close operation and tilt down during retained power operation.
INITIALIZATION FAILURE CONDITIONS
Initialization and teaching of system should be conducted if the following conditions exist:
• sunroof will only move in the UP/CLOSE direction, having a step by step motion
• sunroof does not have any auto operation.
INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.
1. Press the switch to the UP/CLOSE position to tilt the sunroof up fully. When the sunroof reaches the full tilt
up position it will back up a few millimeters and stop.
2. Release the UP/CLOSE switch.
3. Within 5 seconds of releasing the UP/CLOSE switch, press and hold the UP/CLOSE switch again. The
sunroof will move to the full open position and back to the closed position.
NOTE:
If the UP/CLOSE switch is released anytime during this teaching process, all learned profile data will be dis-
carded and the procedure will have to be started over.
4. Release the UP/CLOSE switch. Do not disconnect power for at least two seconds. The sunroof is now ini-
tialized and taught.
Initializing procedure is complete. Confirm proper operation of the sunroof (slide open, slide closed, tilt up, tilt
down).
RE-TEACHING CONDITIONS
Re-teaching of system should be conducted if any of the following conditions exist:
• the sunroof is manually operated using the sunroof wrench with the battery discharged or disconnected.
• the sunroof is manually operated using the sunroof wrench with the key switch in the OFF position and
retained power timed out (after approximately 45 seconds or with a front door open).
• the sunroof motor assembly is replaced with a new one.
• the sunroof motor is removed from the sunroof assembly and operated before it is reinstalled.

TROUBLE DIAGNOSIS
• the sunroof motor is removed from the sunroof assembly and the glass panel position is changed.
RE-TEACHING PROCEDURE
1. Using the UP/CLOSE switch, move the sunroof toward the tilt position until it stops.
2. Release the UP/CLOSE switch.
3. Press the UP/CLOSE switch again and continuously hold. The sunroof will begin to move in about 10 sec-
onds.
4. Continue to hold the UP/CLOSE switch while the sunroof moves in a jogging motion to the full tilt position.
When the sunroof reaches the full tilt position, it will back up a few millimeters and stop.
5. Release the UP/CLOSE switch.
6. Within 5 seconds of releasing the UP/CLOSE switch, press and hold the UP/CLOSE switch again. The
sunroof will move to the full open position and back to the closed position.
NOTE:
If the UP/CLOSE switch is released anytime during this teaching process, all learned profile data will be dis-
carded and the procedure will have to be started over.
7. Release the UP/CLOSE switch. Do not disconnect power for at least two seconds. The sunroof is now re-
taught.

sition. "RETAINED PWR" should be turned "ON" or "OFF" on CONSULT-III
screen when ignition switch ON. Then turn ignition switch OFF for checking re-
tained power operation. CONSULT-III might be stuck if "RETAINED PWR" is
turned "ON" or "OFF" on CONSULT-III screen when ignition switch is OFF.
