REMOVAL
1. Disconnect accelerator pedal position sensor harness connector.
2. Loosen nuts, and remove accelerator pedal assembly.
CAUTION:

Do not disassemble accelerator pedal assembly. Do not remove accelerator pedal position sen-
sor from the accelerator pedal assembly.

Avoid impact from dropping etc. during handling.

Be careful to keep the accelerator pedal assembly away from water.
INSTALLATION
Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION

Check that the accelerator pedal moves smoothly within the whole operation range.

Make sure that accelerator pedal securely returns to the original position.

For the electrical inspection of accelerator pedal position sensor, refer to EC-555, "DTC P2122, P2123
APP SENSOR" (VQ35DE), EC-562, "DTC P2127, P2128 APP SENSOR" (VQ35DE) and EC-576, "DTC
P2138 APP SENSOR" (VQ35DE) or EC-1225, "DTC P2122, P2123 APP SENSOR" (VK45DE), EC-
1232, "DTC P2127, P2128 APP SENSOR" (VK45DE) and EC-1246, "DTC P2138 APP SENSOR"
(VK45DE).
CAUTION:
When harness connector of accelerator pedal position sensor is disconnected, perform “Acceler-
ator Pedal Released Position Learning”. Refer to EC-49, "
Accelerator Pedal Released Position
Learning" (VQ35DE) or EC-698, "Accelerator Pedal Released Position Learning" (VK45DE).

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
[ICC]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS007IE
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for ICC System ServiceAKS006Y8

Do not look straight into the laser beam discharger when adjusting laser beam aiming.

Turn the ON/OFF switch OFF in conditions similar to driving, suchlike Free rollers or Chassis dynamome-
ter.

Do not use the ICC sensor removing from vehicle, disassemble, or remodel the sensor.

Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjusting
laser beam aiming if necessary.
Wiring Diagrams and Trouble Diagnosis AKS006Y9
When you read wiring diagrams, refer to the followings:

Refer to GI-15, "How to Read Wiring Diagrams" in GI section

Refer to PG-3, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit in PG section
When you perform trouble diagnosis, refer to the followings:

Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section

Refer to GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section

VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
Set Checking
1. Press the ON/OFF switch for less than 1.5 seconds.
2. Drive the vehicle between 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
3. Push the COAST/SET switch.
4. Confirm that the desired speed is set as hand is released from the COAST/SET switch.
NOTE:

When there is no vehicle ahead, drive at the set speed steadily.

When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.

The set vehicle speed is displayed on the ICC system indicator in the combination meters.
Check For Increase Of The Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed increases by 1 MPH (1 km/h for CANADA models) as ACCEL/RES switch is
pushed.
NOTE:
The maximum set speed of the vehicle-to-vehicle distance control mode is 90 MPH (144 km/h for CANADA
models).
Check For Decrease Of The Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1 MPH (1 km/h for CANADA models) as COAST/SET switch is
pushed.
NOTE:

Vehicle-to-vehicle distance control mode is automatically turned off when the driving speed lowers to 20
MPH (32 km/h for CANADA models) due to the deceleration of the vehicle ahead.

The minimum set speed of the vehicle-to-vehicle distance control mode is 25 MPH (40 km/h for CANADA
models).
Check For The Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving
Condition) In The Following Cases:
1. When the brake pedal is depressed after the system is turned on.
2. When the select lever is shifted into other than “D” including manual shift.
3. When the ON/OFF switch is turned off.
4. When CANCEL switch is operated.
Check For Restoring The Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation
1. Cancel the system by depressing the foot brake.Then, check that the speed before cancellation is
restored when pressing ACCEL/RES switch with 25 MPH (40 km/h for CANADA models) or above.
2. Cancel the system by shifting the select lever into other than “D”, Then, check if the speed set before the
cancellation is restored when ACCEL/RES switch is pressed.
3. Check if the speed previously set is restored when ACCEL/RES switch is operated with driving 25 MPH
(40 km/h for CANADA models), after canceling vehicle-to-vehicle distance control mode by operating the
CANCEL switch.

ACTION TEST
Revision: 2004 November 2004 FX35/FX45
Check For ON/OFF Switch
1. Start the engine.Then, check the following operations are car-
ried correctly.
2. Vehicle-to-vehicle distance control mode is displayed in speed-
ometer illuminates when ON/OFF switch is pressed “ON” for
less than 1.5 seconds and ready for operation.The illumination
goes off when ON/OFF switch is turned to OFF.
3. “CRUISE” illumination and ICC system display go off when the
key switch is turned to OFF while ON/OFF switch is ON
(“CRUISE” illumination is ON and vehicle-to-vehicle distance
control mode is ready for operation).
Check For ACCEL/RES, COAST/SET, CANCEL Switches
1. Check if ACCEL/RES, COAST/SET, CANCEL switches are operated smoothly.
2. Check if buttons come up as hand is released from the buttons.
Check For Distance Switch
1. Start the engine.
2. Press the ON/OFF switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(long)→(middle)→(short).
NOTE:
The set distance indicator shows 'long' immediately after the engine starts.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Set Checking
1. Press the ON/OFF switch for more than 1.5 seconds.
2. Drive the vehicle between 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
3. Push the COAST/SET switch.
4. Confirm that the desired speed is set as hand is released from the COAST/SET switch.
NOTE:
