Intelligent Key Interlock Storage Procedure
Performing the following operation associates the regist ered driving position with Intelligent Key. When driver
door unlock operation is performed by Intelligent Key or driver door request switch, display of the registered
driving position and turnout operation can be performed.
1.STEP 1
Check the following conditions.
 Ignition switch: OFF
 Initialization: done
 Driving position: registered
>> GO TO 2.
2.STEP 2
1. Push set switch. NOTE:
Memory indicator for which driver seat position is already retained in memory is illuminated for 5 seconds.
2. Push the Intelligent Key unlock button within 5 seconds after pushing memory switch (while the memory indicator is turned ON).
NOTE:
From the time registration is performed, the app licable memory indicator blinks for 5 seconds.

DTC/CIRCUIT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000006248336
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) al lowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
