Nissan Maxima Service and Repair Manual: Memory function
MEMORY FUNCTION : System
MEMORY FUNCTION : System Description
OUTLINE
The driver seat control unit can store the optimum driving positions (seat,
steering column and door mirror position) for 2 people. If the front seat
position is changed, one-touch (pressing desired memory switch) operation
allows changing to the other driving position.
NOTE:
Further information for the memory storage procedure. Refer to Owner's Manual.
OPERATION PROCEDURE
- Turn ignition switch ON
- Press desired memory switch.
- Front seat LH, steering column and door mirror will move to the memorized position.
OPERATION CONDITION
Satisfy all of the following items. The memory function is not performed if these items are not satisfied.
| Item | Request status |
| Ignition position | ON |
|
Switch inputs
|
OFF (Not operated) |
| CVT selector lever | P position |
However, the memory operation can be performed for 45 seconds after opening the front door LH (front door switch LH OFF → ON) even if the ignition switch is OFF.
DETAIL FLOW
| Order | Input | Output | Control unit condition |
| 1 | Memory switch | - | The memory switch signal is inputted to the
automatic drive positioner control unit when memory switch 1 or 2 is
operated.
Memory switch signal is input to driver seat control unit via UART communication |
| 2 | - | Motors (seat, steering, door mirror) | Driver seat control unit operates each motor of seat when it recognizes the memory switch pressed and requests each motor operation to automatic drive positioner control unit via UART communication. The automatic drive positioner control unit operates each motor. |
| Memory switch Indicator | Driver seat control unit requests the flashing of memory indicator to automatic drive positioner control unit via UART communication while either of the motors is operating. The automatic drive positioner control unit illuminates the memory indicator. | ||
| 3 | Sensors (seat, steering column, door mirrors) | - | Driver seat control unit judges the operating seat position with each seat sensor input. The positions of the steering column and outside mirrors are monitored with each sensor signal that is input from auto drive positioner control unit via UART communication. Driver seat control unit stops the operation of each motor when each part reaches the recorded address |
| 4 | - | Memory switch Indicator | Driver seat control unit requests the illumination of memory indicator to auto drive positioner control unit via UART communication after all motors stop. The auto driving positioner control unit illuminates the memory indicator for 5 seconds |
