With CONSULT-III
Check keyfob function in “DATA MONITOR” mode with CONSULT-III. When pushing each button of keyfob,
the corresponding monitor item should be turned as follows.
Without CONSULT-III
Check keyfob function using Remote Keyless Entry Tester J-43241.
OK or NG
OK >> Keyfob is OK.
NG >> GO TO 2
2. CHECK KEY FOB COMPONENTS
1. Open the lid using a coin. CAUTION:
• Do not touch the circuit board or battery terminal.
• The keyfob is water-resistant. However, if it does get wet,immediately wipe it dry.
2. Remove the key fob battery. CAUTION:
• Keep dirt, grease, and other fo reign materials off the elec-
trode contact area.
3. Visually inspect keyfob internal components.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace malfunctioning parts.
3.CHECK KEY FOB BATTERY
Check by connecting a resistance (approximately 300 Ω) so that the
current value becomes about 10 mA.
Is the measurement val ue within specification?
YES >> Key fob battery is OK. Check remote keyless entry
receiver. Refer to BL-80, "

• When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five ID
codes are stored in memory, when an additional code is registered, only the oldest code is erased. If less
than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is added
and no ID codes are erased.
• If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.
• Entry of maximum five ID codes is allowed. When mo re than five ID codes are entered, the oldest ID code
will be erased.
• Even if same ID code that is already in the memory is input, the same ID code can be entered. The code is
counted as an additional code.

INTELLIGENT KEY SYSTEM
System Description
INFOID:0000000005396599
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start func tion) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).
• Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col- umn to prevent accidental shut-off of the ignition sw itch and locking of the steering wheel during driving con-
dition when the vehicle is moving.
CAUTION:
The driver should always carry the Intelligent Key
• Operation of the remote controller buttons on the Inte lligent Key also provides the same functions as the
remote control entry system. (Remote keyless entry functions)
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).
• Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked and the engine started with the mechanical key built into the Intelligent Key.
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It has been made possible to diagnose the system and r egister an Intelligent Key with the CONSULT-III.
DOOR LOCK/UNLOCK FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door by carrying around the Intelli-
gent Key (without some key operation).
