Filament Check
1. Attach probe circuit tester (in volt range) to middle portion ofeach filament.6 volts = Normal filament
2. If a filament is burned out, circuit tester registers 0 or 12 volts.
3. To locate burned out point, move probe to left and right along filament to determine point where tester needle swings
abruptly.
I When measuring voltage, wind a piece of tin foil around
the top of the negative probe and press the foil against the
wire with your finger.

Filament Repair
REPAIR EQUIPMENT
1. Conductive silver composition (Dupont No. 4817 or equivalent)
2. Ruler 30 cm (11.8 in) long
3. Drawing pen
4. Heat gun
5. Alcohol
6. Cloth
REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area clean with acloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive sil- ver composition on break with drawing pen. Slightly overlap
existing heat wire on both sides [preferably 5 mm (0.20 in)] of
the break.
4. After repair has been completed, check repaired wire for con- tinuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
5. Apply a constant stream of hot air directly to the repaired area for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area
and hot air outlet. If a heat gun is not available, let the repaired
area dry for 24 hours.

System Description
The TCU (Time Control Unit) has the following functions.
INTERIOR LAMP TIMER
The interior lamp timer is controlled by the TCU.
The TCU keeps the interior lamp illuminated for about 30 seconds when:
Ithe ignition key is turned from ªONº to ªACCº to ªLOCKº
I the driver's door is unlocked
I a door is opened and then closed while the ignition switch is in the ªOFFº position. (Interior lamp switch
in the ªDOORº position).
The timer is canceled when:
I driver's door is locked, or
I ignition switch is turned ªONº.
IGNITION KEY WARNING CHIME AND LIGHT WARNING CHIME
The ignition key and light warning chime are controlled by the TCU.
The warning chime is combined with the TCU.
The light warning chime will not sound, when ignition switch is in the ªONº or ªSTARTº position. (When power
supply exists at TCU terminal
U01.)
With ignition switch in the OFF position, driver's door open, and lighting switch in 1ST or 2ND position, warn-
ing chime will sound.
Or, with the key in the ignition switch in the ªACCº or ªOFFº position, and locking the driver's door from the
outside, the warning buzzer will sound.
REAR WINDOW DEFOGGER TIMER
The rear window defogger and door mirror defogger system are controlled by the TCU.
The rear window and door mirror defogger operate only for approximately 15 minutes.
POWER DOOR LOCK (Super Lock)
The power door lock (super lock) is controlled by the TCU.
For further information, refer to ªPOWER DOOR LOCK Ð Super Lockº (EL-179).
MULTI-REMOTE CONTROL SYSTEM
The multi-remote control system is controlled by the TCU.
When the following input signals are both supplied:
I Key switch OFF (when ignition key is not inserted in key cylinder);
I door switch CLOSED (when all the doors are closed);
The two above signals are already input into time control unit. At this point, time control unit receives a LOCK
signal from remote controller. Time control unit locks all doors and set super lock with input of LOCK signal
from remote controller.
When an UNLOCK signal is sent from remote controller once, driver's door will be unlocked and release super
lock.
Then, if an UNLOCK signal is sent from remote controller again, all other door will be unlocked.
MULTI-REMOTE CONTROLLER ID CODE ENTRY
For detailed procedure, refer to ªID Code Entry Procedureº (EL-215).
THEFT WARNING SYSTEM
The theft warning system is controlled by the TCU.
For further information, refer to ªTHEFT WARNING SYSTEMº (EL-243).
