Operation DescriptionNIS0020E
SYSTEM DIAGRAM
OPERATION WHEN INSERTING TO KEY SLOT
1. When inserting the Intelligent Key (with transponder) into the key slot, the key switch in the key slot turns
ON, and then it is detected that the Intelligent Key is inserted.
2. When pressing the push-button ignition switch at that time, BCM starts the IVIS (NATS) antenna amplifier
integrated with the key slot and starts the IVIS (NATS) ID communication with the transponder integrated
with the Intelligent Key.
3. BCM sends the IVIS (NATS) ID verification result to ECM via CAN communication and performs the ID
verification.
4. If the IVIS (NATS) ID verification result is OK, BCM sends the key ID verification OK signal to Intelligent
Key unit via CAN communication line.
5. The Intelligent Key unit sends the steering unlock signal to the steering lock unit when receiving the sig-
nal. Then, it sends each power supply request signal to PDU (Power Distribution Unit) after unlocking the
steering lock.
6. If the Intelligent Key unit judges that the engine start condition is satisfied, it sends the starter request sig-
nal via CAN communication to IPDM E/R and turns the starter motor relay ON.
7. The steering lock unit unlocks the latch when receiving the signal. PDU starts the power distribution
according to the power supply position when receiving the signal.
NOTE:
If it is not in the engine start condition*, the starter motor relay is turned OFF. Therefore, the engine cannot be
started and the power distributions of ACC, ON, and LOCK are performed only according to the push-button
ignition switch operation.
*: For the engine start condition, refer to BL-251, "
PUSH-BUTTON IGNITION SWITCH OPERATION PROCE-
DURE" .
OPERATION WHEN INTELLIGENT KEY IS CARRIED
By carrying the Intelligent Key, the engine start/stop operation can be performed only when pushing the push-
button ignition switch.
For the details of the function, refer to BL-127, "
INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION" .
PUSH-BUTTON IGNITION SWITCH OPERATION PROCEDURE
The power supply position changing operation can be performed with the following operation.
NOTE:
When an Intelligent Key is carried and when it is inserted to the key slot, the following operation is the
same.
When starting the engine, the Intelligent Key unit monitors the engine start conditions (brake pedal opera-
tion, A/T selector lever position, vehicle speed, and steering lock condition).

Revision: 2006 January2006 M35/M45
Unless each start condition is fulfilled, the engine will not response regardless of how many times the
push-button ignition switch is pushed. At that time, illumination repeats the position in the order of LOCK
ACC ON LOCK.
*1: When the A/T selector lever position is N position, the engine start condition is different according to the vehicle speed.
At vehicle speed of 5 km/h or less, the engine can start only when the brake pedal is depressed.
At vehicle speed of 5 km/h or more, the engine can start even if the brake pedal is not depressed. (It is the same as “Engine stall
return operation while driving”.)
*2: When the A/T selector lever position is in any position other than P position and when the vehicle speed is 5 km/h or more, the
engine stop condition is different.
Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short
a time, the operation may be invalid, so properly press and hold to prevent the incorrect operation.)
Press the push-button ignition switch 3 times within 1.5 seconds. (Emergency stop operation)
ECM Re-Communicating FunctionNIS0020F
Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent
Key unit, but only when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)
NOTE:
When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS-IVIS/NVIS.
If multiple keys are attached to the key holder, separate them before work.
Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Insert the registered Intelligent Key (*2), turn ignition switch to “ON”.
*2: To perform this step, use the key that has been used before performing ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.

and brake switch until its threaded end contacts stopper.
4. With the threaded end of the stop lamp switch and brake switch
contacting the bracket, rotate the switch clockwise by 45
to
secure.
CAUTION:
Make sure that the clearance (C) between bracket and end
of stop lamp switch and brake switch is within the standard.
Refer to BR-6, "
Inspection and Adjustment" .
5. Check pedal play.
CAUTION:
Make sure that stop lamps goes off when pedal is released.
6. Start engine to check brake pedal depression height when
depressed. Refer to BR-6, "

On-Board Inspection and ServiceNFS000P6
OPERATION CHECK
With engine stopped, change vacuum to atmospheric pressure by
depressing brake pedal several times. Then with brake pedal fully
depressed, start engine and when vacuum pressure reaches the
standard, make sure that clearance between brake pedal and floor
panel decreases.
AIR TIGHT CHECK
Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change vacuum to atmospheric pressure. Make sure that dis-
tance at intervals of 5 seconds between brake pedal and floor
panel gradually increases.
Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Precautions for Brake ControlNFS000Q1
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is normal condition.
When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and oil leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in
wire near the control unit.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
–When replacing the following parts with parts other than genuine parts or making modifications: Suspen-
sion-related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-
related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-
related parts (roll bar, tower bar, etc.).
–When driving with worn or deteriorated suspension, tires and brake-related parts.
