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:
+remote controller or control unit is replaced.
+an 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 six times within 10 seconds.
Turn ignition key switch to ``ACC'' position. (The hazard warning lamps will then
¯ash twice.
Push any button on the new remote controller once. (The hazard warning lamps will
then ¯ash 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. Any attempt to enter more will be
ignored.
No Yes
ADDITIONAL ID CODE ENTRY
Release the door lock, then lock again
with driver side knob lock switch.
Open driver side door or turn the ignition key switch to ``OFF'' position.
END.
After entering the identity (ID) code, check the operation of multi-remote con-
trol system.
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.
+Any ID codes cannot be entered after termination of the ``setting mode''.

C/U INITIALIZATION When replacing any of the following three components, C/U initialization is necessary.
[NATS ignition key/IMMU/ECM]
SELF-FUNCTION CHECK ECM checks its own NATS communication interface by itself.
SELF-DIAGNOSTIC RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialisation is performed, all ID previously registered will be erased. So all NATS ignition
keys must be registered again.
The engine cannot be started with an unregistered key. In this case, the system may show ``DIFFER-
ENCE OF KEY'' or ``LOCK MODE'' as a self-diagnostic result on the CONSULT screen.
HOW TO READ SELF-DIAGNOSTIC RESULTS
NOTE:
+If trip number is more than 1, MIL does not blink.
+Time data is not indicated for TB45E engine models.
