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.
Fuses and Relays
2007 > 2.7L V6 GASOLINE >
INSPECTION
FUSE
1. Be sure there is no play in the fuse holders, and that the fuses are held securely.
2. Are the fuse capacities for each circuit correct?
3. Are there any blown fuses ?
If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew
first and completely eliminate the problem before installing a new fuse.
RELAY
1.Be sure that the relays are held the each module securely.
2. Are the relay types for each circuit correct?

TROUBLESHOOTING
Check the following items prior to performing Power Sliding Door System service.
1. Manual movement
Make sure the sliding door moves manually. Place the ON/OFF switch on the overhead console in the OFF
position. Move the door manually and check for proper door fit and latch effort. Check for interference with other
body parts such as latch striker, trim, and weather seals.
2. Battery voltage
Make sure the battery is fully charged. The PSD system is an electronic device and requires a minimum battery
voltage to operate. The PSDM(Power sliding door module) monitors the battery voltage present at the PSDM input
battery input and will not permit operation if the battery voltage is out of range.
3. Fuses
Two fuses protect the battery supply to the PSDM(Power sliding door module), one for Power, and one for logic.
Check that the fuses are intact
4. Repeat Operations
Make sure the customer has not been operating the PSD repeatedly while the vehicle is turned off. The battery will
be discharged and the PSDM(Power sliding door module) will not permit operation.
5. Vehicle on Steep Grade
Make sure the customer has not been operating the PSD system when the vehicle is parked on a steep grade
(greater than 30%). The system will operate but the force of gravity and normal flex of the vehicle body may affect
proper operation.
6. Obstacle Detection
The obstacle detection force is not adjustable. Factors that may affect the force are vehicle grade, battery voltage,
or dirt in sliding door tracks.
7. Outside handle response time
When the vehicle has been parked and OFF, there may be a delay before power operation starts after the outside
handle is pulled. This is normal because the PSDM(Power sliding door module) must wake up and check for proper
conditions before starting a power open operation.
8. The sliding doors are not identical. Open and close times and obstacle detection efforts may vary when comparing
the two doors. This is normal and is caused by vehicle build conditions such as door fit and rolling resistance.
9. Scan tool Diagnostic tool
Connect Scan tool to the K- line and check status of system.

ADJUSTMENT
POWER SLIDING DOOR INITIALIZATION
A learn cycle must be performed whenever the power is removed, a Power Sliding Door component is removed or
replaced, or a sliding door adjustment is performed. The learn cycle enables the Power Sliding Door control module
(PSDM) to learn the range of full travel and effort required to power the Sliding Door which allows it to perform
properly and safely.
POWER SLIDING DOOR SYSTEM RESET
Certain conditions may require that the PSD system be reset 1. Remove the MEMORY fuse that provides power to the PSDM.
2. Wait 1 minute. Replace fuse. Initialize PSDM.
INITIALIZATION PROCEDURE
1.Manually close and latch the sliding door.
2. Power the sliding door open using the remote control, Open/Close switch, B- pillar switch, or handle.
3. Power the door close from full open to full closed position.
4. Power the door open again to full open position.
ALTERNATE METHOD
1.Remove the black connector (J2) from the PSDM.
2. Wait a short time. Replace connector. Initialize PSDM.
a.The PSD system initialization must start from the primary or secondary latched position.
b. Obstacle detection shall be active during Sliding Door initialization.
c. Work on level ground.
