CAN Communication System DescriptionBIS000WG
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBIS000WH

ID Code Entry ProcedureBIS000WW
KEY FOB ID SET UP WITH CONSULT-II
NOTE:

If a key fob is lost, the ID code of the lost key fob must be erased to prevent unauthorized use. A
specific ID code can be erased with CONSULT-II. However, when the ID code of a lost key fob is not
known, all controller ID codes should be erased. After all ID codes are erased, the ID codes of all
remaining and/or new key fobs must be re-registered.

When registering an additional key fob, 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 old-
est 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.

Entry of maximum five ID codes is allowed. When more than six 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.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.

If a key fob is lost, the ID code of the lost key fob must be erased to prevent unauthorized use. A specific
ID code can be erased with CONSULT-II. However, when the ID code of a lost key fob is not known, all
controller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or
new key fobs must be re-registered.
To erase all ID codes in memory, register one ID code (key fob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new key fobs must be re-registered.

When registering an additional key fob, 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 key fobs, repeat the procedure “Additional ID code
entry” for each new key fob.

Entry of maximum five ID codes is allowed. When more than six 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 DescriptionBIS000WZ

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock
function) and start the engine (engine start function) by carrying around the Intelligent Key, which operates
based on the results of electrical key-ID verification using two-way communications between the Intelli-
gent Key and the vehicle

Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote keyless entry system. (Remote keyless entry functions)

As an ignition key warning function, when a door lock is locked or unlocked with request switch or remote
controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.

Even if the Intelligent Key battery runs down, the door locks can be locked and unlocked and the engine
started with the mechanical key built into the Intelligent Key.

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, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK/UNLOCK, TRUNK OPEN FUNCTION
Operation Description

When the driver door, passenger door, or trunk open request switch is pressed, Intelligent Key unit sends
a request signal from the outside key antenna corresponding to the pressed request switch, key-ID verifi-
cation is performed using two-way communication with Intelligent Key, and if ID is successfully verified, a
door lock/unlock request signal is sent to BCM using CAN communication to lock/unlock the door lock.

When door is locking, door is unlocked, when door is unlocking, door is locked.

When door lock is locked/unlocked by door request switch operation, hazard lamps flash and Intelligent
Key warning buzzer sounds.

With the locking operation of door request switch, door lock actuators of all door are locked.

When trunk open request switch is pushed, trunk lid is opened.
Operation Condition
Auto Door Lock Function
After the door request switch in the driver or passenger door is operated and the vehicle door locks are
unlocked, all the doors are automatically locked unless the mechanical key is inserted into the ignition knob,
the ignition knob is pressed, any door request switch is pressed, any one of the doors is opened, or an Intelli-
gent Key remote control button is operated within 2 minutes.
