Title: SEAT: REAR POWER SEAT CONTROL SYSTEM: INITIALIZATION; 2016 - 2020 MY Sienna [12/2015 -        ]

INITIALIZATION

HINT:

  • The seatback position is initialized at the factory before shipment, so initialization is not normally required.

    There is an initialization function for cases when reinitialization is required.

  • Before performing initialization procedure and initialization release steps, make sure that the rear No. 2 seat assembly is correctly installed on the vehicle.

1. INITIALIZATION RELEASE PROCEDURE

HINT:

Before starting the following procedure, make sure that the seatback position is stored in the fold seat control ECU and reclining motor (the seatback position is initialized).

(a) Press and hold the stowing/return switch.

(b) Within 10 seconds of pressing and holding the stowing/return switch, press the folding switch 5 times with the stowing/return switch held down.

HINT:

If any of the following is performed during the initialization release steps, the release steps will be canceled.

  • Press any switch other than the stowing/return switch and folding switch while pressing the stowing/return switch for 10 seconds.
  • Release the stowing/return switch within 10 seconds.
  • Press the folding switch 6 times while pressing the stowing/return switch for 10 seconds.

(c) If the folding switch is pressed 5 times within 10 seconds of pressing and holding the stowing/return switch, the initialization release operation is complete.

HINT:

After the initialization release steps are completed, turn the engine switch on (IG) and check that the 3RD SEAT indicator on the combination meter is on. If the 3RD SEAT indicator remains off even after the initialization release steps are completed, perform the initialization release steps again.

2. INITIALIZATION PROCEDURE

HINT:

  • Before starting the following procedure, make sure that the seatback position is not stored in the fold seat control ECU or reclining motor.
  • If initialization has been completed, reinitialization cannot be performed. If reinitialization is required, release the initialization before starting reinitialization.

(a) Press the stowing/return switch to set the seat to the sitting position.

(b) Press and hold the rear power seat switch until the seatback is completely folded down.

(c) Continue pressing the rear power seat switch for another 1 second with the seatback folded down. Initialization is complete and the buzzer sounds.

HINT:

  • If initialization has not been completed, the 3RD SEAT indicator in the meter will come on regardless of the positions of the seatback and the seat leg.
  • If the buzzer does not sound, initialization has not been completed properly. Perform the initialization procedure again.
  • After initialization is completed, turn the engine switch on (IG) and check that the 3RD SEAT indicator on the combination meter goes off. If the 3RD SEAT indicator remains on even after initialization is completed, perform the initialization procedure again.
