TILT UP OPERATION
When the tilt switch is operated for tilt up, ground is supplied

to sunroof motor assembly terminal 4

through sunroof switch terminal 4

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will tilt up.
TILT DOWN OPERATION
When the tilt switch is operated for tilt down, ground is supplied

to sunroof motor assembly terminal 10

through sunroof switch terminal 6

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will tilt down.
SLIDE OPEN OPERATION
When the switch is operated for slide open, ground is supplied

to sunroof motor assembly terminal 9

through sunroof switch terminal 3

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will slide open.
SLIDE CLOSE OPERATION
When the switch is operated for slide close, ground is supplied

to sunroof motor assembly terminal 3

through sunroof switch terminal 1

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will slide closed.
RETAINED POWER OPERATION
When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds.
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)" .
MEMORY RESET PROCEDURE
To reset the sunroof motor memory from any sunroof position (full open, partially open, closed, partially
vented, and vented), push and hold the sunroof tilt switch in the forward (DOWN) position until the sunroof is
fully closed. After it has closed all the way, push and hold the tilt switch forward (DOWN) for more than 2 sec-
onds to re-establish the motor preset position. The sunroof should now operate normally.
INTERRUPTION DETECTION FUNCTION
The CPU (central processing unit) monitors the sunroof motor operation and the sunroof position (fully-closed
or other) by the signals from the sunroof motor.
When sunroof motor detects an interruption during the following sliding close operations, sunroof switch con-
trols the motor for open and the sunroof will operate until it reaches full open position.

Operation Procedure
1. After turning OFF the ignition switch, connect CONSULT-II and the CONSULT-II CONVERTER to the data
link connector.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
2. Touch "START (NISSAN BASED VHCL)", "AIR LEVELIZER", "WORK SUPPORT" in order on the CON- SULT-II screen.
If "AIR LEVELIZER" is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
CAUTION:
When "START (NISSAN BASED VHCL)" is touched immediately after starting the engine or turning
on the ignition switch, "AIR LEVELIZER" might not be displayed in the "SELECT SYSTEM" screen.
In this case, repeat the operation from step 2.
3. Select "STANDARD HEIGHT LEVEL", "ADJUST HEIGHT INI" or "CLEAR HEIGHT INI" on the "SELECT WORK ITEM" screen.
NOTE:
Read and perform screen instructions if "STANDARD HEIGHT LEVEL" or "ADJUST HEIGHT INI" is
selected.
4. Touch "START" to begin the desired work support.
