3. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The mirror heater relay is built in engine room junction block.
Also the relay is constructed with a relay block that is in the junc-
tion block as a unit. To disconnect the wire harness connecting
with relay block is impossible. If the relay has a malfunction, re-
place it with junction block assembly wire harness together.
4. INSPECT DEFOGGER WIRE
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires.
Do not use detergents or glass cleaners with abrasive in-
gredients.
When measuring voltage, wrap a piece of tin foil around the
tip of the negative probe and press the foil against the wire
with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5VOkay (No break in wire)
Approx. 10V or 0VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
wire on the battery side.
(e) Place the voltmeter negative (-) lead with the foil strip
against the wire on the ground side.
(f) Slide the positive (+) lead from battery to ground side.
(g) The point where the voltmeter deflects from several V to
zero V is the place where the defogger wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but voltage gradually increases
to about 12 V as the meter probe moves to the other end.

5. IF NECESSARY, REPAIR DEFOGGER WIRE
(a) Clean the broken wire tips with grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire for
repair.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).
(d) Using a fine tip brush, apply a small amount of the agent
to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.
6. w/ Mirror heater:
INSPECT MIRROR HEATER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
5 and the negative (-) lead to terminal 12.
(b) Check that the mirror becomes warm.
HINT:
It will take a short time for the mirror to become warm.

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)
