IGNITION SWITCH
GENERAL INFORMATIONM1543009901274
IGNITION KEY REMINDER BUZZER
The ignition key reminder buzzer will sound under
the following condition, and warn the driver to
remove the ignition key.
•The driver's door is opened when the ignition
switch is at "LOCK" (OFF) or "ACC" position
without removing the ignition key.
However, the lamp reminder buzzer will take
precedence over this function.
DOOR LOCK PREVENTION FUNCTION
If the key is left in the ignition switch while the driver’s
door opened or the assistant door opened, all door
are automatically unlock to prevent locking the
ignition key in the vehicle after door is locked.
IMMOBILIZER SYSTEM
The immobilizer system consists of the ignition key
with a transponder, the immobilizer-ECU, and the
engine-ECU or engine-A/T-ECU . Only
the registered ignition key permits the engine to start,
therefore, the engine can never be started by means
of a forged key or by connecting the ignition wiring
directly. The system is significantly safe and reliable
against theft. In addition, the driver has only to turn
the ignition switch to the "ON" position to activate the
immobilizer system. If the requirements for starting the engine are not satisfied, the engine will be
immobilized. If a registered ignition key is lost, all
your ignition keys need to be registered again using
MUT-II/III to ensure security (Refer to P.54A-20). An
additional ignition key can be registered as follows
(only if no ignition keys are lost):
•Using MUT-II/III (Refer to P.54A-20).
OPERATION
1. When the ignition switch is turned to "ON"
position, the engine-ECU or
engine-A/T-ECU sends a requirement for
the encrypted code to the immobilizer-ECU (at
this time, the engine is remobilized).
2. When the immobilizer-ECU receives the
requirement from the engine-ECU or
engine-A/T-ECU , the immobilizer-ECU
supplies power to the transponder inside the
ignition key via the antenna. The energized
transponder sends the encrypted code back to the
immobilizer-ECU via the antenna.
3. The immobilizer-ECU judges the encrypted code
with its code logic in itself. If they are identical, the
immobilizer-ECU sends the encrypted code to the
engine-ECU or engine-A/T-ECU.
4. If the engine-ECU or engine-A/T-ECU can
not receive the encrypted code, the engine will be
immobilized.

Encrypted code registration criteria table
The ignition key contains a transponder (small
transmitter), which retains an unique encrypted code.
Under any of the conditions below, the encrypted
code should be registered in the immobilizer-ECU
again. The immobilizer-ECU can retain maximum
eight different encrypted codes. This means that
maximum eight ignition keys can be registered.

DIAGNOSIS PROCEDURE
STEP 1. Check for presence of other key near the
key in the ignition.
Q: Is there any other key near the key in the ignition?
YES :
Move the other key well away from key
being used. Retest the system.
NO : Go to Step 2.
STEP 2. Check that the engine start using the
spare ignition key which encrypted code has
been registered.
Q: Does the engine start using the spare ignition key
for which the encrypted code has been registered?
YES :
Replace the ignition key that does not work.
Then register the password (secret code)
and encrypted code P.54A-20. Retest the
system.
NO : Go to Step 3.
STEP 3. Check whether the diagnosis code is
reset.
Q: Which diagnosis code is set, code No.11 or 12 the
encrypted code has been registered?
Code No.12 is set :
Refer toP.54A-11.
Code No.11 is set : Go to Step 4.
STEP 4. Connector check: Immobilizer-ECU
connector C-202-1.
Q: Are immobilizer-ECU connector C-202-1 in good
condition?
YES :
Replace immobilizer-ECU and Then
register the password (secret cod) and
encrypted code P.54A-20. Retest the
system.
NO : Repair or replace the damage
component(s).
Code No.12: Encrypted Codes are Not identical or not Registered
DIAGNOSIS CODE SET CONDITION
The encrypted code sent by the transponder is not
the same encrypted code which is registered in the
immobilizer-ECU.
NOTE: Diagnosis code No.12 is always set together
with MPI system diagnosis code No.P0513.
TROUBLESHOOTING HINTS
•The encrypted code in the ignition key has not
been properly registered.•Malfunction of immobilizer-ECU.
DIAGNOSIS PROCEDURE
Was the encrypted code registered?
YES :
Replace the immobilizer-ECU and then
re-register the encrypted code (Refer to
P.54A-20).
NO : Register the encrypted code (Refer to
P.54A-20).
