< SERVICE INFORMATION >
INTERIOR ROOM LAMP
• through front door key cylinder switch LH terminal 2
• through grounds M57 and M61.
At the time the front door LH is opened, the BCM detects the front door LH is unlocked. It determines that the
interior room lamp timer operation conditions are met, and interior room lamp ON for 30 seconds.
When the key is in ignition key cylinder (key switch ON), or ignition knob switch is pushed, power is supplied
• through key switch and ignition knob switch terminal 1
• to BCM terminal 37, or
• through key switch and ignition knob switch terminal 3
• to Intelligent Key unit terminal 27.
When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
When the ignition knob switch is released, power supply to intelligent key unit is terminated. The BCM detects
that the key has been removed, determines that interior room lamp timer conditions are met, and turns room
lamp ON for 30 seconds.
When the front door LH opens → closes, and key is not inserted in key switch (or ignition knob switch is
released), BCM terminal 47 changes between 0V (door open) → 12V (door closed). BCM determines that
conditions for room lamp operation are met, and turns room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:
• Front door LH is locked (with keyfob or front door key cylinder switch LH).
• Front door LH is opened (front door switch LH).
• Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior room lamp is left ON, it will not be turned OFF even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
After lamps are turned OFF by the battery saver system, the lamps illuminate again when
• front door key cylinder switch LH is locked or unlocked
• door is opened or closed
• key is removed from ignition key cylinder or inserted in ignition key cylinder, or the ignition knob switch is
pushed or released.
Interior lamp battery saver control time period can be changed by the function setting of CONSULT-III.

• 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.
