System DescriptionNBEL0206OUTLINENBEL0206S01Electric sunroof system consists of
ISunroof switch
ISunroof motor
IPower window relay
ISmart entrance control unit
Smart entrance control unit controls retained power operation.
OPERATIONNBEL0206S02The sunroof can be opened or closed and tilted up or down with the sunroof switch.
AUTO OPERATIONNBEL0206S03The 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 OPERATIONNBEL0206S04When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds
Ito power window relay terminal 2
Ifrom smart entrance control unit terminal 5.
Ground is always supplied
Ito power window relay terminal 1
Ithrough body grounds.
When power and ground are supplied, power window relay continues to be energized, and the electrical sun-
roof can be operated.
The retained power operation is canceled when the driver or passenger side door is opened.
INTERRUPTION DETECTION FUNCTIONNBEL0206S05The CPU of sunroof motor monitors the sunroof motor operation and the sunroof position (full closed or other)
for sunroof by the signals from encoder and limit switch in sunroof motor.
When sunroof motor detects interruption during the following close operation,
Iautomatic close operation when ignition switch is in the ªONº position
Iautomatic close operation during retained power operation
sunroof switch controls the motor for open and the sunroof will operate about 150 mm (5.91 in).

System Description=NBEL0210OPERATIVE CONDITIONNBEL0210S01The drive position can be set in 2 ways, manually and automatically.
Manual OperationNBEL0210S0101The driver's seat can be adjusted for sliding, reclining, front cushion height and rear cushion height with the
LH power seat switches. The manual operation can be adjusted with the IGN key in any position.
Automatic OperationNBEL0210S0102The driver's seat is adjusted to the proper positions for the driver automatically, in 3 different ways: MEMORY
AUTOMATIC SET, AUTOMATIC EXITING SETTING and AUTOMATIC SET RETURN. (Automatic Drive Posi-
tioner = ADP)
CONDITIONS INHIBITING AUTOMATIC OPERATIONNBEL0210S02Automatic memory setting procedures are suspended under any of the following conditions:
1) When vehicle speed is more than 7 km/h (4 MPH).
2) When driver's side power seat switch is turned on.
3) When any two of the switches (set switch and memory switches 1 and 2) are turned ON.
4) When cancel switch is turned on.
5) When selector lever is in any position other than ªPº.
6) When ignition switch is turned to ªSTARTº position.
(Operation resumes when ignition switch is returned to ªONº.)
7) When detention switch malfunction is detected:
IDetention switch failure is sensed when detention switch remains off for at least 2 seconds at a vehicle
speed of greater than 7 km/h (4 MPH).
FAIL-SAFE SYSTEMNBEL0210S03Output FailureNBEL0210S0301When the ignition switch is in the ON position, if any of the parts (indicated in the following chart) move more
than the specified amount within a period ªT2º when no ªONº input is sent from any of the switches (indicated
in the following chart), or an output from the automatic drive positioner is not produced, an output failure is
sensed. Motor operation will be suspended automatically, and all automatic operations will be ineffective. (In
this case, the motor will not operate manually.)
OPERATED PORTION T2 Allowable measurement
Seat sliding Approx. 2.5 sec. Within 6 mm (0.24 in)
Seat reclining Same as above Change angle within 1É
AbsolvingNBEL0210S0302When moving selector lever back to ªPº position after having moved it to any position except ªPº, fail-safe
operation will be canceled.
INITIALIZATIONNBEL0210S04After reconnecting battery cable, perform initialization procedure A or B. If initialization has not been performed,
automatic drive positioner will not operate.
PROCEDURE A
1) Insert key in the ignition key cylinder. (Ignition switch is in ªOFFº position.)
2) Open,close,open driver side door. (Do not perform with the door switch operation.)
3) End
PROCEDURE B
1) Drive the vehicle at more than 25 km/h (16 MPH).
2) End

MEMORY AUTOMATIC SET=NBEL0210S05Two drive positions can be retained in the memory. Press memory switch to set driver's seat to preset posi-
tion.
SEL592W
NOTE:
IWhen memory switch for which driver's seat positions are already retained in memory is pressed, new seat
positions will be retained in memory in place of the previously set positions.
IDrive position is erased from the memory when battery cable is disconnected more than 30 seconds. After
connecting battery cable, perform initialization procedures.

NOTE:
1) Do not keep cancel switch pressed as it will not operate.
2) Automatic exiting setting will be performed.
3) The driver's seat position (see the following Table) operates in the order of priority.
