ENCRYPTED CODE REGISTRATION METHOD
AND RESETTING THE CODE TO THE
FACTORY SETTING
Register the encrypted code in the immobilizer-ECU and then
reset the code to the factory setting after parts have been
replaced.
Replacement partEncrypted
code
Ignition keyNecessary
Ignition key ring antenna and immobilizer-ECUNecessary
Engine-ECU*Necessary
NOTE
* : If the engine-ECU is replaced, the ignition key ring antenna
and immobilizer-ECU and ignition key should be replaced
together with it.
Each engine-ECU has an individual information for
immobilizer-ECU, and the individual information is registered
in the immobilizer-ECU.
ENCRYPTED CODE REGISTRATION METHOD
If using an ignition key that has just been newly purchased,
or if the immobilizer-ECU has been replaced, you will need
to register the encrypted codes for each ignition key being
used into the immobilizer-ECU. (A maximum of eight different
encrypted codes can be registered.)
Moreover, when the immobilizer-ECU has been replaced, you
will need to use the MUT-II
to register the password that
the user specifies into the immobilizer-ECU. (Refer to the
MUT-II
instruction manual for instructions on using the MUT-II
.)
Caution
Because registering of the encrypted codes is carried
out after all previously-registered codes have been
erased, you should have ready all of the ignition keys
that have already been registered.

CHASSIS ELECTRICAL -Clock or Center Display54A-54
BEFORE REMOVING THE BATTERY
The Center display has a large amount of data unique to the vehicle in its memory. When the battery
cable is disconnected, that memory is affected as shown in the table below. Accordingly, it is necessary
to make sure that you take notes of important information before disconnecting the battery cable.

SWS -General InformationSWS -General Information54B-5
HEADLAMP WASHER
If the headlamp washer switch at the steering
column is placed in the ON position when the ignition
switch is in the ACC or ON position and theheadlamp switch is in the ON position, the headlamp
washer drive signal is turned ON for 0.5 second.
IGNITION KEY HOLE ILLUMINATION LAMP
When the ignition switch is turned to LOCK (OFF) or
ACC position with the driver’s door opened, the
ignition key hole illumination lamp is illuminated.
If the door is closed in that state, the lamp goes out
after 30 seconds. Vehicles with keyless entrysystem, it illuminates for 30 seconds after the
ignition key is removed. In either case the lamp goes
out when the ignition switch is turned to ON position.
HEADLAMP
Headlamp Automatic Shutdown Function
If the ignition switch is turned to LOCK (OFF) or
ACC position, when the headlamps are on, the
headlamps will be switched off in three minutes.
If the driver’s door is opened within that three-minute
period, the headlamps will be switched off
automatically. This prevents the battery from
discharged.
In addition, if the headlamps are turned on when
the ignition switch is at LOCK (OFF) or ACC position,
the headlamps will not be switched off.Headlamp Dimmer Switch Automatic Reset
Function
This function allows the dimmer switch to be reset
to the low-beam position whenever the headlamp
switch is turned ON.
Daytime Running Lamp (DRL) Function

If the ignition switch is turned to ON when the
headlamps and tail lamps are off, the headlamps
(low-beam) and tail lamps turn on.
FLASHER TIMER
Turn-signal Lamp
When the ignition switch is turned to ON position
and turn-signal lamp switch is placed in the ON
position for right or left turn signaling, the system
generates turn-signal lamp drive signals (flashing
signals).
The system also notifies of a blown turn-signal lamp
bulb by shortening the flashing intervals of the
corresponding indicator lamp.Hazard Warning Lamp
The system detects a change from ON to OFF
of the hazard lamp input signal and activates the
hazard lamps if they are not in operation or
deactivates the lamps if they are operating (reversal
of state between activation and deactivation).
FRONT FOG LAMP
If the front fog lamp switch is turned ON at the
condition that the headlamp or the tail lamp is turned
ON (including the illumination by the automatic
lighting function), the front fog lamp is turned ON.Whenever the tail lamps are turned on at the next
time, the front fog lamps will always be off regardless
of the switch positions. In addition, if the tail lamp
is switched off by the automatic lighting system,
the front fog lamp will also be switched off. However,
the front fog lamp will be illuminated when the tail
lamp is switched on.
