Memory Positioning Systems: Description and Operation

System Description

OPERATIVE CONDITION
The drive position can be set in 2 ways, manually and automatically.

Manual Operation
The 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 Operation
The 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 Positioner = ADP)

CONDITIONS INHIBITING AUTOMATIC OPERATION
Automatic 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 "P".
6. When ignition switch is turned to "START" position.
(Operation resumes when ignition switch is returned to "ON".)
7. When detention switch malfunction is detected:
- 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.)

Absolving
When moving selector lever back to "P" position after having moved it to any position except "P", fail-safe operation will be canceled.

INITIALIZATION
After 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 "OFF" 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
Two drive positions can be retained in the memory. Press memory switch to set driver's seat to preset position.




PROCEDURE FOR STORING MEMORY

NOTE:
- When 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.
- Drive position is erased from the memory when battery cable is disconnected more than 30 seconds. After connecting battery cable, perform initialization procedures.




SELECTING THE MEMORIZED POSITION






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 Table) operates in the order of priority.




AUTOMATIC EXITING SETTING
"Exiting" positions:
Driver's seat ... Slides about 40 mm (1.57 in) rear from normal sitting position.




AUTOMATIC SET RETURN
With driver's seat set to the "exiting" position, operating one of the above procedures moves it to the position previously retained in memory.
