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
