Operation Check
SEAT: FRONT POWER SEAT CONTROL SYSTEM: OPERATION CHECK
1. CHECK FRONT POWER SEAT FUNCTION
(a) Check the basic functions.
(1) Operate the power seat switches and check to make sure each seat function works:
* Sliding
* Front vertical
* Lifter
* Reclining
* Lumbar support (up - down) (for Driver Side)
* Lumbar support (forward - back)
* Cushion sliding (for Driver Side)
* Headrest
2. CHECK POWER SEAT MOTOR ASSEMBLY (SLIDING, FRONT VERTICAL, LIFTER, RECLINING, LUMBAR SUPPORT, CUSHION SLIDING AND HEADREST)
(a) Check the PTC operation inside the power seat motor.
HINT
The PTC thermistor's resistance increases when the power seat switch is held down even after the power seat has been moved as for as possible in one direction. If the resistance increases beyond a specified level, current is cut to prevent a short circuit.
NOTICE:
* The inspection should be 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 power seat switch and move the seat as much as possible in one direction. Keep the seat in that position for approximately 60 seconds.
(2) Operate the power seat switch again and continue to try to move the seat in the same direction as in the previous step. Measure the amount of time elapsed before current is automatically cut (the sound of the motor stops).
Standard:
4 to 90 seconds
(3) After current has been cut, release the power seat switch and wait for approximately 60 seconds.
(4) Operate the same power seat switch and move the seat in the opposite direction. Check that the motor operates.
3. CHECK MEMORY AND SEAT RESTORING OPERATION
(a) Turn the engine switch on (IG).
(b) Move the seat to the foremost and uppermost positions via the seat switch.
(c) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M1 switch and SET switch are pressed and held, or the SET switch is pressed and then the M1 switch is pressed within 3 seconds.
(d) Move the seat out of the foremost and uppermost positions via the seat switch.
(e) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M2 switch and SET switch are pressed and held, or the SET switch is pressed and then the M2 switch is pressed within 3 seconds.
(f) Move the seat out of the rearmost and lowermost positions via the seat switch.
(g) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M3 switch and SET switch are pressed and held, or the SET switch is pressed and then the M3 switch is pressed within 3 seconds.
(h) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the foremost and uppermost positions (memorized positions) when the M1 switch of the memory switch is pressed.
(i) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves out of the foremost and uppermost positions (memorized positions) when the M2 switch of the memory switch is pressed.
(j) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the rearmost and lowermost positions (memorized positions) when the M3 switch of the memory switch is pressed.
(k) Move the shift lever to P and check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the memorized position when the M1, M2 or M3 switch is pressed.
(l) After the engine switch is turned off and the driver side door or passenger side door is opened, check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the memorized position when the M1, M2 or M3 switch is pressed within 180 seconds.
(m) After the engine switch is turned off and the driver side door is opened and then closed, check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the memorized position when the M1, M2 or M3 switch is pressed within 60 seconds. (Only for driver side)
(n) Check that the following procedures erase the recorded seat positions of switches M1, M2 and M3: fully slide the seat forward or rearward; hold M1, M2 or M3; disconnect the cable from the negative (-) battery terminal; and wait for 3 minutes.
4. MEMORY CALL FUNCTION
(a) AUTOMATIC MEMORY CALL OPERATION INSPECTION
(1) With the transmitter's recognition code registered into the memory system, perform an entry unlock or wireless unlock operation. Open the driver door and check that the front seat, front seat belt anchor, steering wheel and outer rear view mirror automatically move to the positions recorded in memory.
(b) MEMORY REGISTRATION (WITH WIRELESS FUNCTION)
(1) Prepare by recording the driving position through the memory switch (M1, M2 or M3).
(2) With the engine switch off and the driver door closed, press and hold both of the following: a memory switch (M1, M2 or M3) and transmitter switch. Continue holding the switches until the answer-back buzzer sounds.
HINT
Either the LOCK or UNLOCK switch on the transmitter can be pressed.
(c) MEMORY REGISTRATION (WITH WIRELESS FUNCTION, CARD TYPE)
(1) Prepare by recording the driving position through the memory switch (M1, M2 or M3).
(2) Hold only the transmitter to be registered.
(3) With the engine switch off and the driver door closed, press and hold both of the following: a memory switch (M1, M2 or M3) and door lock control switch. Continue holding the switches until the answer-back buzzer sounds.
