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 a
cloth 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
Ithe driver's door is unlocked
Ia 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:
Idriver's door is locked, or
Iignition 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
inside, 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-145).
MULTI-REMOTE CONTROL SYSTEM
The multi-remote control system is controlled by the TCU.
When the following input signals are both supplied:
IKey switch OFF (when ignition key is not inserted in key cylinder);
Idoor 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-179).
THEFT WARNING SYSTEM
The theft warning system is controlled by the TCU.
For further information, refer to ªTHEFT WARNING SYSTEMº (EL-209).
TIME CONTROL UNIT (TCU)
EL-180

FUNCTION
IThe TCU has the following control functions.
Item Details of control
Direction indicatorsSwitches the director indicators (Left, Right or All) when the combination switch or hazard
switch is operated.
Light warning chimeSounds warning chime when driver's door is opened with light switch in the 1st or 2nd
position and ignition switch ªOFFº.
Ignition key warning chimeSounds warning chime when driver's door is opened with key in ignition and the driver
door lock knob is moved from the ªunlockº position to the ªlockº position.
Rear window defogger timerTurn off rear window defogger and door mirror heater, if equipped, about 15 minutes
after the rear window defogger switch is turned ªONº.
Battery saverShuts off interior lamp in 30 minutes if any door is left open when ignition switch is
ªOFFº. The battery saver will reset if ignition switch is cycled or any door is opened or
closed.
Interior lamp timerKeep interior lamp illuminated for about 30 seconds when:
Idriver's door is unlocked,
Ithe ignition is switched off,
Idriver's door is opened and then closed.
The timer is cancelled, and interior lamp turns off when:
Idriver's door is locked, or
Iignition switch is turned ªONº.
Theft warning
systemNormal operationMonitors doors, hood, boot lid, door locks, volumetric sensors (if not excluded) and igni-
tion when armed.
Flashes the direction indicators and sounds the horn for 30 seconds in case one of the
monitored sensors is triggered.
Diagnostic mode Indicates the last three alarm triggers by flashing the direction indicators.
Central door lock Centrally locks and unlocks the vehicle
Super lock Activates and de-activates the super lock system.

Checks
Once in Diagnostic Mode (and after identifying the last three alarm triggers in case a theft warning system is
equipped on the vehicle), the following inputs can be tested.
USER ACTION TCU Reaction COMPONENT TESTED
Driver's door opened from closed
(all other doors closed)Hazards flash once Driver's door open signal
Passenger or rear door opened from closed
(all other doors closed)Hazards flash once Door open signal for opened door
Driver's door locked from unlocked Hazards flash once Driver's door status signal
Passenger door locked from unlocked Hazards flash once Assist door status signal
Rear doors locked from unlocked
(with ultrasonic model)Hazards flash once Rear doors status signal
Ultrasonics cancel switch is pressed
(with ultrasonic model)Hazards flash once U/S cancel signal
Trunk or back door is opened from closed Hazards flash once Trunk open signal
Hood is opened from closed
(with ultrasonic model)Hazards flash once Hood open signal
Hazard switch is pressed from off Hazards flash once Hazard switch signal
Turn signal switch is moved to left from off Hazards flash once Left turn signal
Turn signal switch is moved to right from off Hazards flash once Right turn signal
Key turned to lock position in door Hazards flash once * Key cylinder lock switch signal
Lighting switch turned 1st position or 2nd
position from offHazards flash once Tail lamp signal
Key put in ignition cylinder from out Hazards flash once Key in detect signal
Central unlock switch is pressed Hazards flash once Central unlock/Trunk release signal
*) Hazards may flash a second time because of Driver's door status signal change. The min. delay time between flash actions is
100 ms.
In case the system does not operate as described above, check the concerned circuit for open or short.
After completion, the Diagnostic Mode can be switched off by pressing the rear defogger switch or by turning
the ignition to ªONº. The hazard lamp will flash at 3 Hz for 3 seconds to confirm that Diagnostic Mode has
been switched off.
