AUTOMATIC DRIVE POSITIONER — IVMS
EL-441
System Description
OPERATIVE CONDITION
The drive position and mirror can be set in 2 ways, manually and automatically.
Manual operation
The driver’s seat can be adjusted for sliding, reclining, front cushion height, rear cushion height, and lumbar
support with the LH power seat switches. The steering column can be adjusted for tilt and reach (telescopic)
with the steering switch. The manual operation can be adjusted with the IGN key in any position.
Automatic operation
The driver’s seat and steering column are 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 Positioner = ADP)
CONDITIONS INHIBITING AUTOMATIC OPERATION
Automatic memory setting procedures are suspended under any of the following conditions:
(a) When vehicle speed is more than 7 km/h (4 MPH).
(b) When driver’s side power seat switch, tilt or telescopic steering switch is turned on.
(c) When any two of the switches (set switch and memory switches 1 and 2) are turned ON.
(d) When cancel switch is turned on.
(e) When selector lever is in any position other than “P”.
(f) When ignition switch is turned to “START” position.
(Operation resumes when ignition switch is returned to “ON”.)
(g) When any of the following malfunctions are detected:
I
Steering tilt lock detection
(Steering tilt lock is sensed when tilt sensor signal value does not change for a certain period of time.)
I
Steering tilt/telescopic sensor failure detection
(Sensor failure is sensed when sensor output is less than 0.1 volts or greater than 4.9 volts.)
I
Detention switch abnormality detection
[Detention 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 SYSTEM
Output failure
When 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 “T2” when no “ON” 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 1°
Steering tilt
Same as above
Change angle within 1°
Absolving
I
When moving selector lever back to “P” position after having moved it to any position except “P”, fail-safe
operation will be canceled.
I
If self-diagnosis is performed using CONSULT-II, fail-safe operation will be canceled.
