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
motor assembly controls the motor until full up position (when tilt down operate) or 125 mm (4.92 in) or more to
open direction (when slide close operate).
The function is operated in the following conditions.

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

close operation and tilt down during retained power operation.
INITIALIZATION PROCEDURE
If the battery is disconnected, the sunroof motor connector is disconnected 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 the SLIDE OPEN/TILT DOWN switch for approximately 1 second or more.
3. Initialization procedure is completed. Confirm proper operation of the sunroof (slide open, slide close, tilt
up, tilt down.)

CONSULT-II Function (BCM)NIS0023V
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II START PROCEDURE
Refer to GI-38, "CONSULT-II Start Procedure" .
ACTIVE TEST
WORK SUPPORT
DATA MONITOR
BCM diagnostic test item Check item diagnostic test mode Content
RETAINED PWRWork support Changes setting of each function.
Data monitor Displays the input data of BCM in real time.
Active test Gives a drive signal to a load to check the operation.
Test Item Description
RETAINED PWRThis 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 PWRRap 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.).
Work item Description
IGN ON SW Indicates (ON / OFF) condition of ignition switch
DOOR SW–DR Indicates (ON / OFF) condition of front door switch driver side
DOOR SW–AS Indicates (ON / OFF) condition of front door switch passenger side
