1.DESCRIPTION
The wireless door lock remote control system and smart key system have the memory call function.
The memory call function utilizes the transmitter key ID to recall recorded seat position, outer mirror
position, tilt and telescopic position, and seat belt anchor position preferences.
The driver seat ECU records all the positions. When each ECU detects an operation (see the charts
below), the driver seat ECU outputs a signal to restore all the positions.
2.CHECK IF MEMORY CALL FUNCTION OF WIRELESS DOOR LOCK CONTROL SYSTEM
AND SMART KEY SYSTEM ARE CANCELLED
a. After a door is unlocked by the transmitter, perform an "operation" from the chart below. Check
that the "position" to the right of each operation can function and is not limited in any way. Check

*2: Smart key system
If the result is not as specified, inspect the tilt and telescopic.
4.CHECK FRONT POWER SEAT FUNCTION
a. Check the basic functions.
1. Operate the power seat switches and check to make sure each seat function works:
Sliding
Front vertical
Lifter
Reclining
Lumbar support
Cushion sliding
Headrest
OperationTilt and Telescopic Position Operation
Key is inserted to the key cylinder*1 Engine switch is
pushed*2Vertical tilt position
Key is inserted to the key cylinder*1 Engine switch is
pushed*2Telescopic flexibility (lengthening and
shortening)

signaling that the seat position has been recorded.
3. Change the position of the seat and then press the M2 switch. Check that the buzzer sounds
for 0.1 seconds and the seat automatically moves to the position in step (c)-(1).
d. Check the M3 switch.
1. Using the seat switches, fully slide the seat rearward, fully recline the seatback rearward and
fully lower the seat cushion and headrest.
2. Press and hold down switches M3 and SET. Check that the buzzer sounds for 0.5 seconds,
signaling that the seat position has been recorded.
3. Change the position of the seat and then press the M3 switch. Check that the buzzer sounds
for 0.1 seconds and the seat automatically moves to the position in step (d)-(1).
e. Check that the switches M1, M2 and M3 cause the seat to move to the recorded seat positions
under these conditions: turn the ignition switch to the LOCK position, remove the key from the key
cylinder, open the driver side door and press M1, M2 or M3 within 30 seconds.
f. Check that the following procedures will erase the recorded seat positions of switches M1, M2 and
M3: press and hold the power seat slide switch, disconnect the battery's negative terminal cable,
and wait for at least 1 minute.
g. Restore the seat's memory.
1. Using the seat switches, fully slide the seat forward, fully recline the seatback forward, and
fully raise the seat cushion and headrest.
2. Using the seat switches, fully slide the seat rearward, fully recline the seatback rearward and
fully lower the seat cushion and headrest.
HINT:
This will restore the seat's memory of the seat's maximum positions. However, it will not restore
any recorded seat positions to switches M1, M2 or M3.
h. Attempt to record a seat position by pressing and holding the SET switch and two other switches
