CHECK POWER SEAT FUNCTION
| *1 | Reclining Function |
Check the basic function.
Operate the power seat switches and check that seat function operates properly:
Reclining function
CHECK REAR SEAT MOTOR (RECLINING FUNCTION)
Check the PTC operation inside the power seat motor.
Tech Tips
The PTC thermistor's resistance increases when the rear power seat switch is held down even after the power seat has been moved as much as possible in one direction. If the resistance increases beyond a specified level, current is cut to prevent a short circuit.
Note
The inspection should be performed with the seat installed in the vehicle.
Perform the 4 steps below to check the full range of motion for each power seat function.
Choose a power seat function. Operate the rear power seat switch and move the seat as much as possible in one direction. Keep the seat in that position for approximately 60 seconds.
Operate the rear 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 that elapses before current is cut (the sound of the motor stops).
After current has been cut, release the rear power seat switch and wait for approximately 60 seconds.
Operate the same rear power seat switch and move the seat in the opposite direction. Check that the motor operates.
