Power Seat System
SEATS
• Malfunction of reclining operation
D: ADJUSTMENT
NOTE:
The calibration procedures apply only to the mem-
ory-equipped seat on the driver’s side.
1. INITIALIZATING CONDITIONS
Perform the initializing operation to the memory
module when the following conditions are met.
• When the seat was removed from vehicle.
• When the memory module was replaced.
• When the slide rail assembly or backrest hinge
and motor assembly was removed or replaced.
• When the pulse generated while the seat is mov-
ing differs from the actual distance. (When memory
replay operation is not normally carried out)
2. INITIALIZATION PROCEDURE
NOTE:
• Initialize the records inside the module by per-
forming all the following steps regardless the item
order.
• Buzzer sounds once when keeping the switch
operation for three seconds with each seat in lock*
status.
• After the completion of all items for initialization
process, the buzzer sounds three times when fin-
ishing the final operation and turning the switch
from ON to OFF.
1) Move the seat backward using slide switch, and
keep the seat lock* status for three seconds or
more.
2) Move the seat downward using tilt switch, and
keep the seat lock* status for three seconds or
more.
3) Move the seat downward using lifter switch, and
keep the seat lock* status for three seconds or
more.
4) Tilt the seatback forward using reclining switch,
and keep the seat lock* status for three seconds or
more.
* :Seat lock is the status that there is no pulse out-
put from the encoder within the specified period of
time although the switch is being operated.
NOTE:
When the following conditions are met, the initializ-
ing operation is cancelled even though the proce-
dure is carried out halfway.
• Any operation interval between each initialization
procedures from 1) to 4) exceeded 10 second.
• All operations throughout initialization procedure
1) to 4) was not performed.
• During initialization procedure, power supply
was cut off, or the voltage to the memory module
exceeded the range of operating voltage.
Step Check Yes No
1 CHECK SWITCH.
1) Disconnect the connector of power seat
switch assembly.
2) Measure the resistance between connector
terminals when moving the switch to reclining
forward and reclining backward. <Ref. to SE-22,
CHECK POWER SEAT SWITCH, INSPEC-
TION, Power Seat System.>
Is there any problem on the
inspection result? Go to step 2 . Replace the power
seat switch assem-
bly.
2 CHECK HARNESS.
1) Disconnect the power seat switch connector
and reclining motor connector.
2) Measure the resistance between the power
seat switch connector and reclining motor con-
nector.
Connector & terminal
(R201) No. 2 — (R200) No. 4:
(R201) No. 1 — (R200) No. 3:
Is the resistance less than 10
Ω ?
Go to step
3
. Check power seat
harness.
3 CHECK RECLINING MOTOR.
1) Connect the power seat switch connector
and reclining motor connector.
2) Apply 12 V to the reclining motor and check
the motor rotation.
Connector & terminal
(R200) No. 3 (+) — (R200) No. 4 (–):
(R200) No. 4 (+) — (R200) No. 3 (–):
Does the motor rotate nor-
mally? Check for tempo-
rary poor contact
or mechanical
trouble in reclining
hinge. Reclining motor
problem. Replace
the backrest hinge
and motor assem-
bly.
