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

TROUBLE DIAGNOSIS
• 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-17, "
Work Support" .
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 open or close automatically, use the following procedure to return sunroof operation to
normal.
NOTE:
If the sunroof switch is released at any time during step 3, the procedure must be started over again. Leave
the ignition switch ON for at least 2 seconds after this procedure.
1. Push the ignition switch to the ON position.
2. Hold the sunroof switch in the tilt up position. Release the switch when the s unroof has reached the full tilt
up position.
3. Within 5 seconds of releasing the switch in step 2, hold the sunroof switch in the tilt up position again. The sunroof will move from the open position and back to t he close position. Release the switch only when
the sunroof has reached the full closed position.
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 sunroof toward the tilt position until it stops.

Description
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.
