- Mechanical key

 NATS trouble diagnosis, system initialization and additional registration of other mechanical key IDs must be
carried out using CONSULT-III hardware and SECURITY CARD.
When NATS initialization has been completed, the ID of the inserted mechanical key or mechanical key IDs
can be carried out.
 Possible symptom of NATS malfunction is “Engine cannot start”. In C11, the engine can be started with the
Intelligent Key system and NATS. Identify the possible causes according to “Work Flow”, Refer to SEC-4,
"Work Flow".
 If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce-
dure, refer to SEC-7, "
ECM RE-COMMUNICATING FUNCTION : Description".
PRECAUTIONS FOR KEY REGISTRATION
 The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID.
Therefore the registered Intelligent Key is necessary for this procedure. Before starting the registration oper-
ation collect all registered Intelligent Keys from the customer.
 The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in
mechanical key) to BCM.
The Intelligent Key ID registration is the procedure that registers the ID to Intelligent Key unit.
 When performing the Intelligent Key system registration only, the engine cannot be started by inserting the
key into the key cylinder. When performing the NATS registration only, the engine cannot be started by using
the mechanical key.
SECURITY INDICATOR
 Always flashes with ignition knob released (ignition knob switch: OFF) condition on ignition knob LOCK posi-
tion.
 Always flashes with ignition knob released (ignition knob switch: OFF) condition on mechanical key removed
position.
 Turns ON steady when the NATS is activated.
MAINTENANCE INFORMATION
CAUTION:
It is necessary to perform NATS ID registration when replacing any of the following part.
If it's not (or fail to do so), the electrical system may not operate properly.

SYSTEM DESCRIPTION
NATS (Nissan Anti-Theft System) has the following immobilizer functions:
 Engine immobilizer shows high anti-theft performance to prevent engine start by other than the owner.
 Only a key with key ID registered in BCM and ECM can start engine, and shows high anti-theft performance
to prevent key from being copied or stolen.
 Security indicator always flashes with mechanical key removed condition (key switch: OFF).
 Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system. Refer to XX-XX,
"*****".
 If system detects malfunction, security indicator illuminate when ignition switch is turned to ON position.
 If the owner requires, ignition key ID can be registered for up to 5 keys.
 During trouble diagnosis or when the following parts have been replaced, and if ignition key is added, regis-
tration* is required.
*1: All keys kept by the owner of the vehicle should be registered with ignition key.

-BCM
- Ignition key
- ABS actuator control unit

 NATS trouble diagnosis, system initialization and additional registration of other Ignition key IDs must be car-
ried out using CONSULT-III hardware and SECURITY CARD.
When NATS initialization has been completed, the ID of the inserted ignition key or ignition key IDs can be
carried out.

BCM performs the ID verification with the slave control units (ECM, ABS actuator, EPS column assy, IPDM E/
R, combination meter).
If either slave control unit is replaced by used part, perform initialization with CONSULT-III. But if the control
unit is replaced by new part, the system does not need initialization.

REMOVAL
WARNING:
When servicing the SRS, do not work from directly in front of air bag module.
CAUTION:
 Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least
3 minutes.
 Do not tap or bump the steering wheel.
 Do not disassemble the spiral cable.
 Do not allow oil, grease or water to come in contact with the spiral cable.
 Replace the spiral cable if it has been dropped or sustained an impact.
 With the steering linkage disconnected, the spiral cable may snap by turning the steering wheel
beyond the limited number of turns. The spiral cable can be turned counterclockwise about 2.5 turns
from the neutral position.
1. Disconnect the negative and positive battery cables, then wait at least 3 minutes.
2. Set the front wheels to the straight-ahead/neutral position.
3. Remove the steering wheel. Refer to ST-8, "
Removal and Installation".
4. Remove the column cover upper and lower.
5. Disconnect wiper and washer switch connector (1). Then while
pressing tabs (2), pull wiper and washer switch away from spiral
cable to remove.

6. Disconnect lighting and turn signal switch connector (1). Then
while pressing tabs (2), pull lighting and turn signal switch
toward driver door to remove.
7. Remove the screws, then release the tab at the top and pull the
spiral cable away from the steering column assembly.

INSTALLATION
Installation is in the reverse order of removal.
 Align spiral cable correctly when installing steering wheel, refer to
ST-8, "
Removal and Installation". Make sure spiral cable alignment
and centering marks (B) are matched and in the neutral position.
The neutral position is detected by turning left 2.6 revolutions from
the right end position, ending with the locating pin (A) at the top.
Place steering wheel in straight ahead position, then install it with
the locating pin hole (C) directly over spiral cable locating pin.
 After the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer to SRC-11, "
SRS Operation
Check".

Component Description
INFOID:0000000001716729
CAN CommunicationINFOID:0000000001697716
SYSTEM DESCRIPTION
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.
For details, refer to LAN-30, "
CAN System Specification Chart".
Component parts Function
EPS control unit
(Electric power steering control unit) Outputs optimum assist torque signal to EPS motor.
 Reduces output signals to EPS motor and protects EPS motor and EPS control unit when us-
ing power steering continuously and excessively.
 As a fail-safe function, turned off output signal to EPS motor and then enters a manual steer-
ing state, if malfunction is detected in EPS system.
EPS motor Products assist torque by control signal from EPS control unit.
Torque sensor Detects steering wheel turning force and outputs sensor signal to EPS control unit.
Reduction gear Increases motor-produced assist torque by worm gear and transmits it to column shaft.
EPS warning lamp Illuminates if malfunction is detected in electrical system of EPS system.
ECMTransmits the following signals via CAN communication to EPS control unit.
 Engine status signal
ABS actuator and electric unit (con-
trol unit)Transmits the following signals via CAN communication to EPS control unit.
