2. INITIALIZATION OF SEAT ECU

   Note

   Initializing the position control ECU assembly will clear the seat position memory.

   Tech Tips

   
   

   • Use the same procedure for the driver side and front passenger side.

   • Make sure to initialize the position control ECU assembly after replacing the seat assembly or any related parts (including removal and installation).

   • Before initializing the seat ECU, make sure that the D/C CUT fuse is normal.

   • When any of the following conditions are met, the seat position Information in the seat ECU will be cleared.

   
   

   • The power switch is turned off with any of the seat switches being operated and the D/C CUT fuse removed.

   • The power switch is turned off within 1 second of any of the seat switches being operated with the D/C CUT fuse removed.

   • If the seat is in the following positions or conditions after initialization completes, the system returns to the previous condition.

   
   

   • The headrest is folded.

   • The seat is in the extra range due to a slide or reclining operation.

   
   

   1. Reset the ECU:

      
      

      1. Seat position information is cleared. (The seat current position, memorized position and motor end position are cleared. Lift up buckle information is not cleared.))

         
         

         1. Turn the power switch on (IG).

         2. Operate the front vertical power seat switch knob to tilt the front of the power seat downward 3 times.

         3. Operate the rear lifter switch upward within 10 seconds of operating the front vertical switch. Simultaneously operate the reclining switch backward and hold the switches in operation until the buzzer sounds.

   2. Set the ECU 0 value:

      Note

      When initializing the slide and reclining operations, make sure that the headrest does not contact the ceiling. If it appears that contact will occur, operate the lifter downward in advance.

      
      

      1. Operate the slide switch knob to move the power seat to the foremost position. Continue holding the switch for 1 second after the seat has stopped at the foremost position.

         Tech Tips

         After slide initialization and cushion extension, the bottom of the headrest automatically operates and the "auto initialization function" is performed.

      2. Operate the reclining switch knob to move the seatback to the foremost position. Continue holding the switch for 1 second after the seat has stopped at the foremost position.

         Tech Tips

         After reclining initialization and headrest operation, the headrest automatically operates and the "auto initialization function" is performed.

      3. Operate the rear lifter switch knob to move the seat to the lowermost position. Continue holding the switch for 1 second after the seat has stopped at the lowermost position.

      4. Operate the front vertical switch knob to move the seat to the lowermost position. Continue holding the switch for 1 second after the seat has stopped at the lowermost position.

      5. Operate the cushion switch knob to move the seat to the rearmost position. Continue holding the switch for 1 second after the seat has stopped at the rearmost position.

      6. Operate the headrest switch knob to move the headrest to the lowermost position. Continue holding the switch for 1 second after the seat has stopped at the lowermost position.

      7. Operate the headrest switch knob to move the headrest to the rearmost position. Continue holding the switch for 1 second after the seat has stopped at the rearmost position.

   3. Lift Up Buckle (Easy Access Buckle) Initialization:

      
      

      1. Perform the Active Test according to the display on the Techstream.

         
         Body Electrical > Driver Seat > Active Test
