INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
Revision: 2007 April2007 M35/M45
Trouble Diagnosis Symptom Chart 2NIS001Z1
When performing the push-button ignition switch operation when the Intelligent Key is carried, there is a time
difference in the power supply position switching (the power supply changes in approximately 3 seconds)
CAUTION:

Follow Trouble Diagnosis Flowchart referring to “Diagnosis Procedure”. Determine malfunction-
ing condition before performing this diagnosis.

Make sure that vehicle is under the condition shown in “Conditions of vehicle” before starting
diagnosis.

Check systems shown in the “Diagnosis/service procedure” column in this order.
CONDITIONS OF VEHICLE (OPERATING CONDITIONS)

Another Intelligent Key or foreign materials are not inserted in the key slot.
NOTE:
If another Intelligent Key or foreign materials are inserted at push-button ignition switch operation, perform the
immobilizer ID verification first. When the immobilizer ID verification cannot be performed, the system
switches to the Intelligent Key ID verification. Therefore, there is the time difference in the push-button ignition
switch operation.
Trouble Diagnosis Symptom Chart 3NIS001Z2
When performing the push-button ignition switch operation when the Intelligent Key is inserted into the key
slot, there is the time difference in the power supply position switching (the power supply changes in approxi-
mately 3 seconds)
CAUTION:

Follow Trouble Diagnosis Flowchart referring to “Diagnosis Procedure”. Determine malfunction-
ing condition before performing this diagnosis.

Make sure that vehicle is under the condition shown in “Conditions of vehicle” before starting
diagnosis.

Check systems shown in the “Diagnosis/service procedure” column in this order.
CONDITIONS OF VEHICLE (OPERATING CONDITIONS)

A device emitting electromagnetic signals such as a portable telephone or a radio is not used around the
key slot.

The Intelligent Key is inserted into the key slot until it clicks.
NOTE:
If another Intelligent Key is inserted at push-button ignition switch operation, perform the immobilizer ID verifi-
cation first. When the immobilizer ID verification cannot be performed, the system switches to the Intelligent
Key ID verification. Therefore, there is the time difference in the push-button ignition switch operation.

PRECAUTIONS
Revision: 2007 April2007 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.

TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2007 April2007 M35/M45
The Braking Distance Is LongNFS000R6
CAUTION:
The stopping distance on slippery road surfaces might be longer with the ABS operating than when
the ABS is not operating.
1. CHECK FUNCTION
Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector to deactivate
ABS. In this condition, check stopping distance. After inspection, connect connector.
OK or NG
OK >> GO TO procedure 3 “CHECK WHEEL SENSOR AND SENSOR ROTOR”. Refer to BRC-51,
"Excessive ABS Function Operation Frequency" .
NG >> Check brake system.
ABS Function Does Not OperateNFS000R7
CAUTION:
ABS does not operate when speed is 10 km/h (6 MPH) or lower.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp turns OFF after ignition switch is turned on or when driving.
OK or NG
OK >> GO TO procedure 3 “CHECK WHEEL SENSOR AND SENSOR ROTOR”. Refer to BRC-51,
"Excessive ABS Function Operation Frequency" .
NG >> Perform self-diagnosis. Refer to BRC-24, "
Self-Diagnosis" .
Pedal Vibration or ABS Operation Sound OccursNFS000R8
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1. SYMPTOM CHECK 1
Check if there is pedal vibration or operation sound when the engine is started.
Do symptoms occur?
YES >> GO TO 2.
NO >> Perform self -diagnosis. Refer to BRC-24, "
Self-Diagnosis" .
2. SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO procedure 3 “CHECK WHEEL SENSOR AND SENSOR ROTOR”. Refer to BRC-51,
"Excessive ABS Function Operation Frequency" .

Do not operate fuel pump when there is no fuel in lines.
–Fuel level sensor unit and fuel pump (1)
–Fuel pressure regulator (2)
–Fuel tank temperature sensor (3)

Tighten fuel hose clamps to the specified torque.

Do not depress accelerator pedal when starting.

Immediately after starting, do not rev up engine unneces-
sarily.

Do not rev up engine just prior to shutdown.

When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standing-
wave radio can be kept smaller.
–Be sure to ground the radio to vehicle body.
