ON-VEHICLE INSPECTION PROCEDURE 1. INSPECT POWER SEAT MOTOR ASSEMBLY (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 to the maximum 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 has stopped). 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. |
