DESCRIPTION
An optimal seat position set by a driver can be memorized in P/seat unit by memory SW and position SW, which
enables restoration of seat position set by the driver despite seat adjustments.
Furthermore, data is transmitted between P/seat and IPM, DDM, ADM, RAM, FAM, CLUSTER through CAN BUS.
Seat position presets cannot be recalled while driving. An emergency stop function is provided; additional functions are
described below.
1. It conducts manual operation of seat by CAN BUS data transmitted by DDM as well as that of adjustable pedal by
CAN BUS data transmitted by IPM received when operating SW manually.
2. Manual SW behavior when communication stops (back- up behavior)
a. Slide front/rear
b. Recline front/rear
c. Position control of slide motor is possible by manual SW even in case of congestion in CPU or removal of a
fuse for P/seat unit B.
3. 2 memory locations are provided for storing seat, outside mirror, and adjustable pedal presets.
4. The driver seat can be set to slide rearward when the ignition key is removed, and forward when the key is
inserted.
5. 2 additional presets for seat, mirror, and adjustable pedal position can be stored with the RKE transmitter.
OPERATION
MANUAL OPERATION
Manual operation of the driver seat and adjustable pedals is possible provided the transaxle is in 'P' range and the
vehicle speed is 0 MPH. Operation of the manual controls overrides any automatic operation commanded via CAN.
MEMORY OPERATION
1. Pressing the 'M' button on the control panel will place the system into memory storage mode and will result in a
single pulse from the output buzzer.
2. If one of the memory location buttons is pressed and held within 5 seconds of pressing the 'M' button, the output
buzzer will pulse twice to indicate successful storage of seat, mirror, and adjustable pedal positions.
3. The ignition switch must be in the RUN or START position, the vehicle speed must be 0 MPH, and the transaxle
must be in 'P' range to store memory presets.
4. Pressing the 'M' button while recalling a stored preset will halt the preset recall operation.
5. Memory will be cleared if battery is removed.
MEMORY REPLAY OPERATION
1.Pressing one of the memory location buttons will result in the driver seat, outside mirrors, and adjustable pedals
being positioned based on the stored preset data.
2. The ignition switch must be in the RUN position, the transaxle must be in 'P' range, the vehicle speed must be 0
MPH, and the manual functions must not be in operation to recall stored presets.
3. Others
a. Play operation not recorded in the position switch will not be conducted and there will be no buzzer output.
b. If other data is received during preset recall operation, the most recent preset recall signal will take
precedence.
c. If engine is started during preset recall operation, halt preset recall operation, and resume it toward target
position 100ms after Ignition switch is returned to "RUN". However, if the START state lasts over 5 sec., it will
not resume even after returning to RUN.
d. If preset recall order is received during engine start, preset recall operation is inhibited.
e. If input from manual switch for seat and adjust pedal occurs during preset recall operation of seat and adjust
pedal, halt all their preset recall operations.
f. If an error occurs during manual operation of seat and adjust pedal, delete Memory.

DIAGNOSIS AND TESTING - POWER TAILGATE SYSTEM
The power tailgate system is a complex system containing many components. In order to perform conclusive testing,
or receive outputs the power tailgate control module must be checked.
The most reliable, efficient, and accurate means to diagnose the power tailgate system requires the use of a scan tool
and the proper Body Diagnostic Procedures manual. The scan tool can be used to observe current switch status
recorded in the power tailgate control module to help the technician diagnose an inoperative switch.
Before any testing of the power tailgate system is attempted, the battery should be fully charged, all power tailgate
system inhibitors read and understood (Refer to power tailgate system description for list).
Following are quick reference diagnostic tables to help when diagnosing and testing the power tailgate system.
