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.

COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-38
TECHNICAL DESCRIPTION (COMMENT)
The engine-ECU and its associated components, the
combination meter assembly, the wiring harness, or
the connector(s) may be defective.
TROUBLESHOOTING HINTS
•Malfunction of the vehicle speed sensor
•Malfunction of the engine-ECU
•Malfunction of the combination meter assembly
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III actuator test
(1) Connect the MUT-II/III to the diagnosis connector.(2) Use the MUT-II/III to enter simulated vehicle
speed.
Q: Does the speedometer show that simulated vehicle
speed?
YES :
Go to Step 6.
NO : Go to Step 2.
STEP 2. Check the output shaft speed sensor.
(MUT-II/III diagnosis code)
(1) Connect MUT-II/III to the diagnosis connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the automatic transmission system
diagnosis code.
Q: Is automatic transmission system diagnosis code
23 set?
YES :
Refer to P.23A-38.
NO : Go to Step 3.

Features the headlamp automatic shutdown function
to avoid battery drain when the headlamps are left
on. The main features are as follows:
•Extinguishes automatically in three minutes if the
ignition switch is turned off with the lighting switch
on.
•Extinguishes in one second if the driver's door is
opened within that 3-minute period.
•If the headlamps are turned on with the ignition
switch off, the headlamps and tail lamps will
extinguish in three minutes after the driver's door
is opened or closed.
The headlamps are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.

HEADLAMP AIMING
M1542000900538
PRE-AIMING INSTRUCTIONS
1. Inspect for badly rusted or faulty headlamp
assemblies.
2. These conditions must be corrected before a
satisfactory adjustment can be made.
3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not full, place a weight in luggage
room of the vehicle to simulate weight of a full
tank (0.8 kg per litre).
5. There should be no other load in the vehicle other
than driver or substituted weight of approximately
75 kg placed in driver's position.
6. Thoroughly clean the headlamp lenses.7. Place the vehicle on a level floor, perpendicular to
a flat screen 10 m away from the bulb
centre-marks on the headlamp lens.
8. Rock vehicle sideways to allow vehicle to assume
its normal position.
9. Bounce the front suspension through three (3)
oscillations by applying the body weight to hood
or bumper.
10.Four lines of adhesive tape (or equivalent
markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is
aligned with the vehicle centre line.
(2) Measure the distance from the centre-marks
on the headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or
mark on the screen is for reference of vertical
adjustment. Item Standard value Limit

When the front fog lamp switch is turned to ON with
the tail lamp or the headlamp on (the tail lamp switch
or the headlamp switch is ON), the fog lamp relay
turns on, and the fog lamps will illuminate.
If the tail lamps or the headlamps are turned off with
the lighting switch OFF while the fog lamps are on,
the front fog lamps turn off at the same time to
prevent unattended operation.
If the tail lamps are turned off by the headlamp
automatic shutdown function, the fog lamps turn off
at the same time. However, if the tail lamps illuminate
again, the fog lamps do not.
The front fog lamps are controlled by the Smart

1. Before inspection and adjustment, set vehicle in
the following condition:
•Engine coolant temperature: 80 − 90 °C•Lamps, electric cooling fan and accessories: Set
to OFF
•Transmission: Neutral ("N" or "P" for vehicles with
A/T)
•Steering wheel: Straightforward

standard value. <1300, 1600> Refer to GROUP
13A, On-vehicle Service − Basic Idle Speed
Adjustment P.13A-387.
<2000> Refer to GROUP 13B, On-vehicle Service

Standard value: 750 ± 50 r/min
3. When the A/C is running after turning the A/C
switch to ON, and the blower switch to the 3(MH)
or 4(HI) position, check to be sure that the idle
speed is at the standard value.
Standard value: 850 ± 50 r/min
NOTE: It is not necessary to make an adjustment,
because the idling speed is automatically
adjusted by the ISC system. If, however, a
deviation from the standard value occurs for some
