AUTOMATIC DRIVE POSITIONERPFP:28491
System Description AIS002XB

The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
driver positioner control unit can also store the optimum driving positions (driver seat, pedal position and
door mirror position) for 2 people. If the driver is changes, one-touch operation allows changing to the
other driving position.

The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display unit (without NAVI) or display control unit (with NAVI) to driver seat con-
trol unit.

Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position [seat position, steering wheel position (tilt, telescopic) and door mirror position] can be
adjusted with the power seat switch or ADP steering switch or door mirror remote control switch.
NOTE:

The seat can be manually operated with the ignition switch OFF.

The door mirrors can be manually operated with the ignition switch turned ACC or ON.
A U T O M AT I C O P E R AT I O N
NOTE:

Disconnecting the battery erases the stored memory.

After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open)→OFF (close)→ON
(open), the Entry/ Exiting operation becomes possible.

After exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
MEMORY STORING AND KEY FOB INTERLOCK STORING

Store the 2 driving positions and shifts to the stored driving position with the memory switch.
Function Description
Memory switch operation The seat, steering and door mirror move to the stored driving position by pushing
memory switch (1 or 2).
Entry/Exiting functionExiting operation At exit, the seat moves backward and steering wheel moves forward/upward.
Entry operationAt entry, the seat and steering wheel returns from the exiting position to the previous
driving position.
Key fob interlock operationPerform memory operation, exiting operation and entry operation by pressing key fob
unlock button.
Auto operation temporary stop
conditions.When ignition switch turned to START during memory switch operation and return opera-
tion, memory switch operation and entry operation is stopped.
Auto operation stop conditions.

When the vehicle speed becomes 7 km/h (4 MPH) or higher.

When the setting switch, memory switch 1, or 2 are pressed.

When A/T selector lever is in any position other than P.

When the door mirror remote control switch is operated (when ignition switch turned to
ON or ACC).

When power seat switch turned ON.

When ADP steering switch turned ON (telescopic operation or tilt operation).

When door mirror operates (only memory switch operation).

When driver seat sliding Entry/Exiting setting is OFF (only entry/exiting operation).

When steering wheel tilt and telescopic Entry/Exiting setting is OFF (only entry/exiting
operation).

When the tilt and telescopic sensor malfunction is detected.

Detention Switch (P Range Switch) Circuit CheckAIS002XW
1. CHECK FUNCTION
With CONSULT-II
Make sure when the A/T selector lever is in P position, “P POSITION
SW” on the DATA MONITOR becomes ON.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Check voltage between drive seat control unit conductor and
ground.
OK or NG
OK >> Detention switch circuit is OK.
NG >> GO TO 2.
2. CHECK DETENTION SWITCH POWER SUPPLY CIRCUIT HARNESS
1. Key is removed form ignition key cylinder.
2. Disconnect driver seat control unit connector and A/T device
(detention switch) connector.
3. Check continuity between driver seat control unit connector
B152 terminal 17 (PU) and A/T device (detention switch) con-
nector M67 terminal 3 (R/Y).
4. Check continuity between driver seat control unit connector
B152 terminal 17 (PU) and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness between driver seat control unit and A/T device (detention switch).
