(1) Operate the power seat switches and check to make sure each seat function operates properly:

Sliding

Front vertical

Lifter

Reclining

Lumbar support

2. CHECK POWER SEAT MOTOR ASSEMBLY (SLIDING, FRONT VERTICAL, LIFTER, RECLINING)

(a) Check the PTC thermistor operation inside the power seat motor.

HINT
The resistance of the PTC thermistor increases when the front power seat switch is held down even after the power seat has been moved to the farthest possible position in one direction. If the resistance increases beyond a specified level, the current is shut off to prevent a short circuit.

NOTICE:
* Make sure the inspection is performed with the seat installed in the vehicle.
* Perform the 4 steps below for each power seat function.

(1) Choose a power seat function. Operate the front power seat switch and move the seat to the farthest possible position in one direction. Keep the seat in that position for approximately 60 seconds.

(2) Operate the front power seat switch again and continue to try to move the seat in the same direction as in the previous step. Measure the time until the current is shut off (motor operation sound will stop).

Standard:

4 to 90 seconds

(3) After the current is shut off, release the front power seat switch and wait for approximately 60 seconds.

(4) Operate the same front power seat switch and move the seat in the opposite direction. Check that the motor operates.

3. CHECK LUMBAR SUPPORT MOTOR

(a) Check the PTC thermistor operation inside the lumbar support motor.

NOTICE:
Make sure the inspection is performed with the seat installed in the vehicle.

(1) Operate the power seat switch assembly and move the lumbar support to either the foremost or rearmost position. Keep the lumbar support in that position for approximately 60 seconds.

(2) Operate the power seat switch assembly again and continue to try to move the lumbar support in the same direction as in the previous step. Measure the time until current is shut off (motor operation sound will stop).

Standard:

4 to 90 seconds

(3) After current is shut off, release the power seat switch assembly and wait for approximately 60 seconds.

(4) Operate the power seat switch assembly and move the lumbar support in the opposite direction. Check that the motor operates.

4. CHECK MEMORY AND SEAT RESTORING OPERATION

(a) Check the memory and restore operation.

HINT
If the M1 switch and M2 switch are simultaneously pressed while the SET switch is pressed and held, the seat position will not be stored.

(1) Turn the engine switch on (IG) and move the shift lever to P.

(2) Move the seat to the maximum front and upper positions via the seat switch.

(3) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M1 switch and the SET switch are pressed and held, or the SET switch is pressed and then the M1 switch is pressed within 3 seconds.

(4) Move the seat out of the maximum front and upper positions via the seat switch.

(5) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M2 switch and the SET switch are pressed and held, or the SET switch is pressed and then the M2 switch is pressed within 3 seconds.

(6) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the maximum front and upper positions (memorized positions) when the M1 switch is pressed.

(7) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves out of the maximum front and upper positions (memorized positions) when the M2 switch is pressed.

(8) Turn the engine switch off and open the driver door. Check that the buzzer sounds for 0.1 seconds and the seat automatically moves to the memorized position by pressing the M1 or M2 switch within 180 seconds after the engine switch is turned off.

(9) Turn the engine switch off and close the driver door. Check that the buzzer sounds for 0.1 seconds and the seat automatically moves to the memorized position by pressing the M1 or M2 switch within 60 seconds after the engine switch is turned off.

(b) Clear the memory.

(1) Turn the engine switch on (IG).

(2) Press the front power seat switch (front vertical switch) downward 3 times.

HINT
Perform each switch operation within 10 seconds of the previous operation.

(3) Within 10 seconds of the above operation, begin the following operation: perform the rearward reclining operation and upward lifter operation simultaneously for 10 seconds or more (a buzzer sounds for 0.5 seconds). This clears the memory.

5. CHECK MEMORY CALL FUNCTION

(a) Automatic memory call function check

(1) With a transmitter key recognition code registered:

Perform a wireless door unlock operation and check that opening the driver side door causes the following:

The buzzer sounds for 0.1 seconds.

The driver seat and outer mirror automatically move to the memorized positions.

HINT
* The registered transmitter key recognition code is recalled automatically.
* If the automatic memory call function is not operated, the buzzer will not sound.

(b) Memory registration

(1) Prepare by recording the driving position through the memory switch (M1 or M2).

(2) With the driver side door closed, turn the engine switch from on (IG) to off, and while holding down the previously registered M1 or M2 switch, press and hold the unlock switch on the key to be registered until the answer-back buzzer sounds.

(c) Memory deletion

(1) With the driver side door closed, turn the engine switch from on (IG) to off, and while holding down the SET switch, press and hold the unlock switch on the key to be deleted until the answer-back buzzer sounds.

6. CHECK MEMORY CALL EMERGENCY STOP FUNCTION

(a) During a memory call operation, perform one of the following operations and check that the memory call operation stops.

Press a memory switch (M1, M2 or SET).

Press the front power seat switch LH.

7. CHECK POWER SEAT POWER EASY ACCESS SYSTEM

HINT
When troubleshooting a function, first make sure that the function is set to the default setting.

(a) Away function

(1) Turn the engine switch off and move the shift lever to P.

(2) Disengage the seat belt tongue plate from the buckle.

(3) Make sure that the seat slides rearward.

(b) Return function

(1) Turn the engine switch on (ACC or IG) or move the shift lever to P, and then engage the seat belt tongue plate with the buckle.

(2) Make sure that the seat slides forward.
