4. PROBLEM SYSMPTOMS TABLE
NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during sys-
tem operation and was prepared on the assumption of system component troubles (except for the wires and
connectors, etc.).
Always inspect the trouble taking the following items into consideration.
Open or short circuit of the wire harness
Connector or terminal connection fault

REGISTRATION PROCEDURE
1. KEY REGISTRATION IN AUTOMATIC REGISTRATION MODE
(a) Registration of a new transponder key.
HINT:
This must be done when you install a new Transponder key ECU.
The new Transponder key ECU is on the automatic key code registration mode. The already fixed of
key codes for this Transponder key ECU can be registered.
On this type of vehicle, up to 4 key codes can be registered.
A master and sub key are registered automatically.
HINT:
When a key is not inserted in the key cylinder on the automatic registration mode, the security indicator
always comes.
When the immobiliser system operates normally and the key is pulled out, the security indicator blinks.
(b) Automatic registration mode completion
If completing the mode forcibly when registering more than 1 key code on the automatic registration
mode, perform the following procedures.

After registering 1 more key code with master key, perform step (1) or (2) without pulling the key out
or inserting the already registered key.
(1) Turn the ignition switch LOCK " ON 5 times within 10 sec.
(2) With the hand-held tester, require automatic registration mode completion.
2. REGISTRATION OF ADDITIONAL MASTER KEY AND SUB KEY
It is possible to carry out additional registration of the supply key.
HINT:
It is possible to register up to 5 master key codes including the already registered key code.
It is possible to register up to 3 sub key codes including the already registered key code.
When any operation period described below is over, registration mode cannot be completed.
When the next procedure is performed while the previous timer is working, the timer stops counting
time, and then the next timer starts.
When replacing ºIgnition Cylinder Key Setº or ºLock Cylinder Setº, perform registration following the
procedure using the original master key. However, after the registration of the additional master key,
as the original master key and the original sub-key is not necessary any more, erase registration of
those key codes.
For the registration order, it is not necessary to distinguish between Main and Sub.
(Main key and Sub key are automatically identified)
When a registration error in the transponder key ECU is detected, the security indicator indicates the follow-
ing codes.
2 - 1Communication error between the key to be registered and the transponder key
ECU
2 - 2When trying to register the key that is already registered
2 - 3When exceeding the number of keys which can be registered (Master key: 5, Sub
key: 3)

ADJUST HEADLIGHT AIM ONLY
(a) Place the vehicle in the following conditions.
The area around the headlight is not deformed.
The vehicle is parked on a level surface.
Tire inflation pressure is the specified value.
A driver is in the driver's seat and the vehicle is in a state ready for driving (with a tank full).
The vehicle has been bounced several times.
(b) Check the headlight aiming.
(1) Prepare a thick white paper.
(2) Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
(3) Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown
in the illustration.
(4) Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
(5) Draw a vertical line (V line) to where the center line of the vehicle is to be.
(6) Draw 2 vertical lines (by connecting the low and high beam center marks) to where the both head-
lights should strike (V RH and V LH lines).
(7) Draw a horizontal line (by connecting the both low beam center marks) to where the headlights
should strike (H RH and H LH lines).
HINT:
The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
(8) Start the engine.
(9) Turn the headlights ON.
(10) Check that the headlights properly strike the position shown in the illustration.
(11) If not, adjust the lights in the vertical direction.
HINT:
As shown in the illustration, adjust each aim of the RH and LH lights.
(c) When adjusting it in the vertical direction:
Using adjusting bolt A, adjust the headlight aim to within the specified range.
