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 slide 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 DescriptionNIS001SZ
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 UnitNIS001T0
Refer to LAN-27, "CAN COMMUNICATION" .

1. Check the symptom and customer's requests.
2. Understand the outline of system. Refer to RF-11, "
System Description" .
3. According to the trouble diagnosis chart, repair or replace the cause of the malfunction. Refer to RF-16,
"Trouble Diagnosis Chart by Symptom" .
4. Does sunroof system operate normally? If Yes, GO TO 5. If No, GO TO 3.

Active test Gives a drive signal to a load to check the operation.RF-15
Test Item Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned ON or OFF on CONSULT-II screen when ignition switch is ON. Then turn
ignition switch OFF to check retained power operation. CONSULT-II might be stuck if “RETAINED
PWR” is turned to ON or OFF on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWR Rap signal’s power supply period can be changed by mode setting. Selects rap signal’s power
supply period between three steps

MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).
Monitor item Description
