ID Code Entry Procedure
Note:
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will
erase all ID codes previously entered. Therefore, be sure to receive all remote controllers from the
vehicle owner when any ID code entry is performed.
Enter the identity (ID) code manually when:
lremote controller or control unit is replaced.
lan additional remote controller is activated.
To enter the ID code, follow the procedures below.
PROCEDURE
Close all doors and lock driver side door.
Insert and remove the key from the ignition more than seven times within 10 sec-
onds.
Turn ignition key switch to ``ACC'' position. (The hazard warning lamps will then
flash twice.)
Turn ignition key switch to ``OFF'' and remove the key from the ignition.
Push any button on the new remote controller once. (The hazard warning lamps will
then flash twice.)
At this time, the new ID code is entered and all previous ID memory is com-
pletely erased.
b
Do you want to enter any additional remote controller ID codes?
A maximum four ID codes may be entered. (After 4th ID code is entered, the
registration mode is ended.)
No Yes
ADDITIONAL ID CODE ENTRY
Release the door lock, then lock again
with driver side knob lock switch.
Open driver side door.
END.
After entering the identity (ID) code, check the operation of multi-remote con-
trol system.
NOTE:
lIf you need to activate more than two additional new remote controllers, repeat the procedure
``Additional ID code entry'' for each new remote controller.
lAny ID codes cannot be entered after termination of the ``setting mode''.
