System Description

NIS000FW

OUTLINE

Electric sunroof system consists of

●

Sunroof switch

●

Sunroof motor assembly

●

BCM (Body Control Module)

BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.

OPERATION

Sunroof can be opened or closed and tilted up or down with sunroof switch.

AUTO OPERATION

The power sunroof AUTO feature makes it possible to open and close the sunroof without holding the sunroof
switch in the down or up position.

RETAINED POWER OPERATION

When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds

●

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-16, "CONSULT-II Function (BCM)"

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 stop. 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 “Tilt down” “Slide open” “Slide close”. Release the button after the sunroof
“Tilt down” and stops.

4.

Initializing procedure is complete. Confirm proper operation of the sunroof.

INTERRUPTION DETECTION 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 sliding close operation, sunroof switch con-
trols the motor for open and the sunroof will operate until full open position.

●

automatic close operation when ignition switch is in the ON position

●

automatic close operation during retained power operation

CAN Communication System Description

NIS000FX

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.
