      *a Slide Function
      *b Reclining Function
      *c Rear Lifter Function
      *d Front Vertical Function

      Check the basic functions.


      1. Operate the power seat switches and check that the following seat functions operate properly:


        • Slide function

        • Reclining function

        • Rear lifter function

        • Front vertical function

  2. CHECK POWER SEAT FUNCTION (for Front Passenger Seat)


    1. B006LW2C01
      *a Slide Function
      *b Reclining Function
      *c Ottoman Function

      Check the basic functions.


      1. Operate the power seat switches and check that the following seat functions operate properly:


        • Slide function

        • Reclining function

        • Ottoman function

  3. CHECK POWER SEAT MOTOR (for Driver Seat)


    1. Check the PTC operation inside the power seat motor.

      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.

      Tech Tips

      The resistance of the PTC thermistor increases when a switch of the front power seat switch LH*1 or RH*2 is held down even after the 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.


      1. Operate the seat to the furthest position in either the front/rear or up/down direction, and then wait for approximately 60 seconds.

      2. Further operate the seat in the same direction for 90 seconds, and then check that the motor does not operate when operating the seat in the opposite direction.

      3. Turn the front power switch LH*1 or RH*2 off. After approximately 60 seconds, check that the motor operates when operating the seat in the opposite direction.

  4. CHECK POWER SEAT MOTOR (for Front Passenger Seat)


    1. Check the PTC operation inside the power seat motor.

      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.

      Tech Tips

      The resistance of the PTC thermistor increases when a switch of the front power seat switch RH*1 or LH*2 or front power seat switch assembly RH*1 or LH*2 is held down even after the 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.


      1. Operate the seat to the furthest position in either the front/rear or up/down direction, and then wait for approximately 60 seconds.

      2. Further operate the seat in the same direction for 90 seconds, and then check that the motor does not operate when operating the seat in the opposite direction.

      3. Turn the front power switch RH*1 or LH*2 or front power seat switch aseembly RH*1 or LH*2 off. After approximately 60 seconds, check that the motor operates when operating the seat in the opposite direction.

    *A for RHD *B for LHD
    *1 SET Switch *2 M1 Switch
    *3 M2 Switch *4 M3 Switch

    Tech Tips


    • The SET, M1, M2 and M3 seat memory switches are shown in the illustration.

    • The seat position will not be stored if the SET switch and 2 or more of the seat memory switches (for example, M1 switch and M2 switch) are pressed simultaneously.

      If a memorizing operation has failed, release all switches. The seat memory function does not operate unless the switches are released.

    • The seat will not return to the memorized position if 2 or more of the seat memory switches (for example, M1 switch and M2 switch) are pressed simultaneously.

      If a restoring operation has failed, release all switches. The seat memory restoring function does not operate unless the switches are released.
