REMOTE CONTROL ENTRY SYSTEM
ID Code Entry Procedure
Enter the identity (ID) code manually when:
remote controller or control unit is replaced.
an additional remote controller is activated.
To enter the ID code, follow the procedures below.
PROCEDURE
I Close all doors and lock driveis side door. I
Insert and remove the key from the ignition more than six times within 10 seconds.
(Power door lock will then unlock.)
Within
3 seconds after door lock is unlocked, turn ignition key switch to "ACCn posi-
tion and lock the driver's side door.
At this time, the original ID codes are erased.
Push any button on the new remote controller once. (Power door lock will then
unlock.)
At this time, the new ID code is entered. e
Lock driver's side door.
Do you
want to enter any additional remote controller ID codes?
A maximum four ID codes may be entered. Any attempt to enter more will be
ignored.
I Open driver's side door or turn the ignition key switch to 'OFF position. I
No
END.
After entering the identity (ID) code, check the operation of remote control
entry system.
Yes
NOTE
If you need to activate more than two additional new remote controllers, repeat the procedure
"Additional ID code entry" for each new remote controller.
If the same ID code that exists in the memory is input, the entry will be ignored.
Entry of maximum four ID codes is allowed and any attempt to enter more will be ignored.
