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".
