SEATS
• Malfunction of reclining operation
Step
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.>
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.

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.

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.
Power Seat System
Check
Is there any problem on the
inspection result?
Is the resistance less than 10
Ω?
Does the motor rotate nor-
mally?
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.
