OUTLINE
Electric sunroof system consists of

Front door switches

Sunroof switch

Sunroof motor assembly

BCM (body control module)
BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.
OPERATION
Power is supplied at all times

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

through BCM terminal 69

to sunroof motor assembly terminal 5.
With ignition switch in ON or START position, power is supplied

through 10A fuse (No. 59, located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied

to BCM terminal 67 and

to sunroof motor assembly terminal 7

through grounds M57, M61 and M79.

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.

automatic close operation when ignition switch is in the ON position.

automatic close operation during retained power operation.

CONSULT-II Function (BCM)EIS004VW
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II OPERATION
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.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn igni-
tion switch ON.
2. Touch "START (NISSAN BASED VHCL)".
3. Touch "BCM". If "BCM" is not indicated, go to GI-40, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
BCM diagnostic
test item Diagnostic mode

Work item Description
RETAINED PWR SET RAP signal
’s power supply period can be changed by mode setting. Selects RAP sig-
nal ’s power supply period between the following three steps:

MODE 1 (45 sec.) / MODE 2 (OFF) / MODE 3 (2 min.)
Test item Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM to power window system,
power sunroof system. 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 ON. Then turn ignition switch OFF for checking
retained power operation. CONSULT-II might be stuck if "RETAINED PWR" is
turned "ON" or "OFF" on CONSULT-II screen when ignition switch is OFF.
