EXIT ASSIST FUNCTION : System Diagram
EXIT ASSIST FUNCTION : System Description
OUTLINE
When exiting, if the conditions are satisfied, the seat is moved backward from normal sitting position and the steering column is moved up.
The seat slide amount at entry/exit operation can be changed.
NOTE:
OPERATION PROCEDURE
OPERATION CONDITION
Satisfy all of the following items. The exit assist function is not performed if these items are not satisfied.
Item | Request status |
Ignition switch | OFF |
System setting [Entry/exit assist function] | ON |
Initialization | Done |
Switch inputs
|
OFF (Not operated) |
CVT selector lever | P position |
DETAIL FLOW
Order | Input | Output | Control unit condition |
1 | Front door switch LH | - | Driver seat control unit receives front door switch LH signal (open) from BCM via CAN communication |
2 | - | Motors (seat sliding, tilt) | Driver seat control unit operates the seat sliding motor, which
recognizes that the driver side door is opened with ignition switch
OFF.
Driver seat control unit then requests the operations of tilt motor to auto drive positioner control unit via UART communication. The automatic drive positioner control unit operates each motor for a constant amount. |

FUEL CUT CONTROL (AT NO LOAD AND HIGH ENGINE SPEED)
If the engine speed is above 2,000 rpm under no load (for example, the
selector lever position is P or N and
engine speed is over 2,000 rpm) fuel will be cut off after some time. The exact
time when the fuel is cut off varies
