SUNROOF OPERATION

The ground is supplied to the terminals 1, 2, 3, 4 and 5 of sunroof motor assembly by combining the 1, 2, 3, 4,
5 and 6 terminals of sunroof switch.
Sunroof motor assembly operates sunroof in TILT or SLIDE by combining signals of the 1, 2, 3, 4 and 5 termi-
nals.
Ground is supplied

●

to sunroof switch terminal 6

●

through body ground M14 and M78.

SUNROOF SWITCH READING FUNCTION

1.

Description

●

Sunroof switch reads sunroof switch status, and controls various electrical components according to
the results.

●

Sunroof switch reads information of 8 switches by combining five terminals.

2.

Sunroof motor assembly - Operation table of sunroof switch
Reads operation status of sunroof switch by the combination shown in the table.

RETAINED POWER OPERATION

When the ignition switch is turned to “OFF” position from “ON” or “START” position, power is supplied for 45
seconds.

●

to sunroof motor assembly terminal 9

●

from BCM terminal 53.

When power is supplied, the sunroof can be operated.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to 

RF-18, "CONSULT-II Function (BCM)"

 .

ANTI-PINCH FUNCTION

The CPU of sunroof motor 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 slid close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until full up position (when tilt down operate) or
125 mm (4.92 in) or more in an open direction (when slide close operate):

●

close operation and tilt down when ignition switch is in the “ON” position

●

close operation and tilt down during retained power operation.

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.

●

When the battery is out or connector is disconnected while sunroof is operating or within 5 seconds
after sunroof stops.

●

When the sunroof motor is changed.

●

When an emergency handle is used.

●

When the sunroof does not operate normally. (Incomplete initialization conditions)

INITIALIZATION PROCEDURE

If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.

1.

Close the sunroof if it is not in the closed position. It may be necessary to repeatedly push the switch to
close the sunroof. 

2.

Press and hold the TILT UP switch. Do not release the switch, keep pressure on it. After 10 seconds of
depressing, the sunroof will tilt up, then tilt down. Release the button.

3.

Press and hold the TILT UP switch again. Do not release the switch, keep pressure on it. While depress-
ing the switch, the sunroof will “Slide open” “Slide close” “Tilt up” “Tilt down”. Release the button after the
sunroof “Tilts down” and stops.

4.

Initializing procedure is complete. Confirm proper operation of the sunroof (slide open, slide close, tilt up,
tilt down.)

CAN Communication System Description

NIS001CV

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.
