Trouble Diagnoses
If doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.
Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains a
valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and allow
key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.

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).
