1. CHECK FRONT POWER SEAT FUNCTION
(a) Check the basic functions.
*a |
Sliding function |
*b |
Front vertical function |
*c |
Lifter function |
*d |
Reclining function |
*e |
Lumbar support function |
(1) Operate the power seat switches and check to make sure each seat function operates properly:
2. CHECK POWER SEAT MOTOR ASSEMBLY (SLIDING, FRONT VERTICAL, LIFTER, RECLINING)
(a) Check the PTC thermistor operation inside the power seat motor.
HINT:
The PTC thermistor resistance increases when the power seat switch is held down even after the power seat has been moved to as much as possible in one direction. If the resistance increases beyond a specified level, current is cut to prevent a short circuit.
NOTICE:
(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 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 cut (adjuster operation sound stops).
Standard:
4 to 90 seconds
(3) After current is cut, 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.
