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.

ID Code Entry Procedure
Enter the identity (ID) code manually when:
Iremote controller or TCU is replaced.
I an additional remote controller is activated.
Activation of the registration mode:
The vehicle must have been unlocked by either the multi-remote controller or a transponder OK signal (TPOK) from the vehicle's
immobilizer.
Preparation: - Make sure all doors unlock.
- Make sure all multi-remote controllers to be registered are available.
- Make sure the batteries of all multi-remote controllers are in a good condition.
- Make sure all transmitting sources are out of the neighbourhood of the vehicle.
- Make sure the battery of the vehicle is in a good condition.F
Switch ignition-switch exactly six times from the ªLOCKº to the ªONº position within 10 seconds and return the ignition switch to
the ªLOCKº position (leaving the key in the ignition switch).F
After 2 seconds the registration mode is activated. The turn signal lamps will flash twice.
OK NG
Proceed with the registration mode.
NOTE
The registration mode is exited when: IThe ignition-switch is turned to the ªONº position.
I a multi-remote controller ID code had registered after 4 ID codes have been registered (then, all
of the registered ID codes are erased).
I No multi-remote controller or ignition switch input is received within 120 seconds.
Registration mode
G
Press and hold the ªUNLOCKº button of the multi-remote controller.F

Press the ªLOCKº button 3 times.
Release the ªUNLOCKº button.
(At this time, the original (previous) ID code(s) are erased.)EIf the multi-remote controller code
is registered correctly, the turn
signal lamp will flash once.
(If 4 ID codes have been
registered, the turn signal lamp
will flash 3 times.)ENG
Do you want to register another multi-remote controller? (max. 4)
(If 4 controllers have been registered, you should turn the ignition switch to the
ON position.)
NoYe s
FOK
Turn the ignition switch to the ON position.
EIf the multi-remote controller reg-
istration is performed correctly,
the turn signal lamp will flash
twice.
(If 4 ID codes have been
registered, the turn signal lamp
will not flash.)
Take the ignition key out of the ignition switch and confirm the functioning of all

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).
