Front seat:
INSPECT LIFTER MOTOR PTC THERMISTOR OPERATION (): Passenger's seat
a. Connect the positive (+) lead from the battery to terminal 2(1), the positive (+) lead from the ammeter to terminal 1(2) and the negative (-) lead to battery negative (-) terminal, then move the rear edge of seat cushion to the highest position.
b. Continue to apply voltage, and check that the current changes to less than 1 ampere with 4 to 90 seconds.




c. Disconnect the leads from terminals.
d. Approximately 60 seconds later, connect the positive (+) lead from battery to terminal 1(2) and the negative (-) lead to terminal 2(1), and check that the seat cushion begins to descend.
If operation is not as specified, replace the motor.




Front seat:
INSPECT RECLINING MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the motor turns counterclockwise.
b. Reverse the polarity, and check that the motor turns clockwise.
If operation is not as specified, replace the motor.




Front seat:
INSPECT RECLINING MOTOR PTC THERMISTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1, the positive (+) lead from the ammeter to terminal 2 and the negative (-) lead to battery negative (-) terminal, then recline the seat back to the most forward position.
b. Continue to apply voltage, and check that the current change to less than 1 ampere with 4 to 90 seconds.




c. Disconnect the lead from terminals.
d. Approximately 60 seconds later, connect the positive (+) lead from battery to terminal 2 and the negative (-) lead to terminal 1, check that the seat back starts to fall backwards.
If operation is not as specified, replace the motor.




Front seat:
INSPECT LUMBAR SUPPORT MOTOR OPERATION (): Driver's Upper Side Control
a. Connect the positive (+) lead from the battery to terminal 1(2) and the negative (-) lead to terminal 2(1), and check that the lumbar support moves release side.




b. Reverse the polarity, and check that the lumbar support moves forward.
If operation is not as specified, replace the motor.




Front seat:
INSPECT LUMBAR SUPPORT MOTOR PTC THERMISTOR OPERATION (): Driver's Upper Side Control
a. Connect the positive (+) lead from the battery to terminal 2(1), the positive (+) lead from the ammeter to terminal 1(2) and the negative (-) lead to battery negative (-) terminal, then move the front edge of seat cushion to the highest position.
b. Continue to apply voltage, and check that the current changes to less than 1 ampere with 4 to 90 seconds.




c. Disconnect the leads from terminals.
d. Approximately 60 seconds later, connect the positive (+) lead from battery to terminal 1(2), and the negative (-) lead to terminal 2(1), and check that the seat cushion begins to descend.
If operation is not as specified, replace the motor.




Rear seat:
INSPECT SLIDE MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1 and check that the motor turns counterclockwise.
