OUTLINE Electric sunroof system consists of
• Sunroof switch
• Sunroof motor assembly
• BCM (body control module)
BCM supplies power to the sunroof motor. S unroof operation depends on sunroof switch condition.
OPERATION Power is supplied at all times
• through 40A fusible link (letter g , located in the fuse and fusible link box)
• to BCM terminal 70, and
• through BCM terminal 69
• to sunroof motor assembly terminal 7.
When the ignition switch is in the ON or START position, power is supplied
• through 10A fuse [No. 6, located in the fuse block (J/B)]
• to BCM terminal 38, and
• through BCM terminal 68
• to sunroof motor assembly terminal 9.
Ground is supplied
• to BCM terminal 67
• through grounds M57 and M61.
TILT UP/SLIDE CLOSE OPERATION When up/close switch is pressed, ground is supplied

ANTI-PINCH FUNCTION
The CPU (central processing unit) of sunroof motor as sembly 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 oper ate 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 igniti on 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 t he 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 sw itch, 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 th is 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 approximat ely 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.

• 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 sunroo f 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 positi on, it will back up a few millimeters and stop.
5. Release the UP/CLOSE switch.
6. Within 5 seconds of releasing the UP/CLOSE s witch, press and hold the UP/CLOSE switch again. The
sunroof will move to the full open pos ition and back to the closed position.
NOTE:
If the UP/CLOSE switch is released anytime during th is 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.

RETAINED PWR This test is able to supply RAP signal (power) from BCM to power window system,
power sunroof system. Those systems can be operated when turning on "RETAINED
PWR" on CONSULT-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in "OFF" po-
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. Symptom Diagnostic procedure and repair order Refer to page
