TILT UP / SLIDE CLOSE OPERATION
When tilt up / slide close switch is pressed,
Ground is supplied
lto sunroof motor assembly terminal 1
lthrough sunroof switch terminal 3
lthrough sunroof switch terminal 2
lthrough body grounds M21, M80 and M83.
Then, the sunroof tilt up / slide close.
TILT DOWN / SLIDE OPEN OPERATION
When tilt down / slide open switch is pressed,
Ground is supplied
lto sunroof motor assembly terminal 5
lthrough sunroof switch terminal 1
lthrough sunroof switch terminal 2
lthrough body grounds M21, M80 and M83.
Then, the sunroof tilt down / slide open.
AUTO OPERATION
The power sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the
sunroof without holding the sunroof switch in the TILT UP/SLIDE CLOSE, TILT DOWN/SLIDE OPEN position.
ANTI-PINCH FUNCTION
The CPU 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 (when tilt down
operate) or 125 mm (4.92 in) or more in an open direction (during slide close operate).
lclose operation and tilt down when ignition switch is in the ON position.

MEMORY RESET PROCEDURE
1. Please observe the following instructions while confirming the sunroof operation.
NOTE:
Do not disconnect the electronic power while the sunroof is operating or within 5 seconds after the sunroof
stops. (to wipe-out the memory of lid position and operating friction.)
2. Initialization of system should be conducted after the following conditions.
lWhen the battery is out or connector is disconnected while sunroof is operating or within 5 seconds
after sunroof stops.
lWhen the sunroof motor is changed.
lWhen an emergency handle is used.
lWhen the sunroof does not operate normally. (Incomplete initialization conditions)
INITIALIZATION PROCEDURE
If sunroof does not close or open normally, use following procedure to return sunroof operation to normal.
1. Close sunroof if it is not in close position. It may be necessary to repeatedly push TILT UP/SLIDE CLOSE
switch to close sunroof.
2. Tilt up sunroof, and release TILT UP/SLIDE CLOSE switch once.
3. Keep pushing TILT UP/SLIDE CLOSE switch. After 10seconds, glass lid will back up a few millimeters.
then will be stopped at normal tilt up position.
(Keep pushing TILT UP/SLIDE CLOSE switch during this operation.)
4. Within first 10 seconds of releasing TILT UP/SLIDE CLOSE switch, keep pushing TILT UP/SLIDE CLOSE
switch again. After 4 seconds, glass lid will be automatically TILT DOWN®SLIDE OPEN®SLIDE
CLOSE.
(Keep pushing TILT UP/SLIDE CLOSE switch during this operation.)
5. After glass lid stops, release TILT UP/SLIDE CLOSE switch later 0.5 seconds.
6. Initializing procedure is completed. Confirm proper operation of sunroof (slide open, slide close, tilt up, tilt
down).

CAN Communication System DescriptionEIS00D4X
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitEIS00D4Y
Refer toLAN-30, "CAN Communication Unit".
