1. Perform a seat memory operation properly. Refer to OPERATION CHECK .
2. Check that the buzzer sounds for 0.5 seconds to indicate the completion of the memory operation.
   NOTE:

   • The seat position will not be recorded 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.

   OK

   Seat position memory function operates normally.

NG → See step   19 

OK: Go to next step 

1. Perform a seat restoring operation properly. Refer to OPERATION CHECK .
2. Check that the buzzer sounds for 0.1 seconds and the seat automatically moves to the memorized position.
   NOTE:

   • The seat position will not return to the memorized position if the 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.

   OK

   Seat position restoring function operates normally.
