SYSTEM
- Swivels the headlamp to the vehicle-center side until it hits the stopper.
- Returns the swivel angle from the stopper. Completes t
he initialization with regarding the returned position
as the swivel angle 0 ° (straight-forward position).
Swivel Operation
AFS control unit transmits the drive signal to the sw ivel actuator when activation conditions are satisfied.
And swivels the headlamp.
- The swivel starts after steering approximately 20 ° or more from straight-forward position.
NOTE:
The steering angle differs between right turn and left turn.
- The swivel angle becomes the maximum angle toward t he driving direction if the steering angle is approxi-
mately 90 ° or more depending on the vehicle speed. The swivel angle is maintained by shutting off the drive
signal.
- The swivel starts, and returns to the swivel angle 0 ° (straight-forward position) when the steering is returned
to the straight-forward position.
AFS control unit returns the swivel angle to the strai ght-forward position, and stops the swivel regardless of
the steering angle if the operation condition is not satisfied while the swivel angle is 0°.
AFS OFF Indicator Lamp
AFS control unit transmits AFS OFF indicator lamp signal to the combination meter via CAN communication.
Combination meter turns AFS OFF indicator lamp ON /OFF/blinking according to AFS OFF indicator lamp
signal.
- AFS OFF indicator lamp is turned ON for 1 second for the AFS OFF indicator lamp bulb check when the igni-
tion switch is turned ON. AFS OFF indicator lamp is turned OFF within 1 second when the engine starts.
- AFS OFF indicator lamp turns ON when AFS is switched to “OFF” by operating AFS switch.
- AFS OFF indicator lamp blinks (1 second each) if AFS control unit detects a specific DTC.
NOTE:
Combination meter blinks AFS OFF indicator lamp (approximately 1 second each) if AFS OFF indicator
lamp signal is not received from AFS control unit.
HEADLAMP AUTO AIMING
Headlamp Auto Aiming Control Description
AFS control unit controls the headl amp light axis height appropriately according to the vehicle height.
AFS control unit detects the vehicle condition necessa ry for headlamp auto aiming control with the following
signals.
- Height sensor signals (front and rear)
- Vehicle speed signal (received from combination meter via CAN communication)
- Low beam status signal (received from IPDM E/R via CAN communication)
- Engine speed signal (received from ECM via CAN communication)
When the operation conditions are satisfied, AFS cont rol unit transmits the aiming motor drive signal for
adjusting the headlamp axis height.
Headlamp auto aiming operation condition- Headlamp ON
- While the engine running
- Vehicle speed (Control mode is switched according to the driving condition.)
Headlamp Auto Aiming Operation
AFS control unit calculates the vehicle pitch angle fr om the front and rear height sensor signal. AFS control
unit judges the angle for adjusting the axis gap from the preset position.
AFS control unit controls the headlamp axis by c hanging the aiming motor drive signal output according to
the front and rear vehicle height when detecting the follo wing vehicle condition. Output is maintained if other
condition than following is detected.
- Engine starts.
- Headlamp is turned ON.
- Vehicle posture becomes stable after changing the v ehicle posture change is detected with the headlamp
ON and the vehicle stopped.
- Vehicle speed is maintained with the headlamp ON and the vehicle driven.
CAUTION:
Adjusted axis position may differ from the preset position although the headlamp auto aiming acti-
vates properly if the suspension is replaced or worn.

If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when the repair is reconfirmed.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following items:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-cl utch on M/T models, drive position on A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, che ck ASIST for Technical Service Bulletins (TSBs) related
to the concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Chassis ear: J-39570, engine ear, and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
Removing the component(s) in the area that is / are suspected to be the cause of the noise.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be broken
or lost during the repair, resulting in the creation of new noise.
Tapping or pushing/pulling the component(s) that is / are suspected to be the cause of the noise.
Do not tap or push/pull the component(s) with excessive force, otherwise the noise is eliminated only tempo-
rarily.
Feeling for a vibration by hand by touching the component(s ) that is / are suspected to be the cause of the
noise.
Placing a piece of paper between components that are suspected to be the cause of the noise.
Looking for loose components and contact marks. Refer to EXT-8, "
Inspection Procedure".
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
If the cause is insufficient clearance between components:
- Separate components by repositioning or loosening and retightening the components, if possible.
- Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape, or ure-
thane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through the authorized NISSAN Parts
Department.
CAUTION:
Never use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSA N Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

lowing section illustrates ways to simulate the c onditions/environment under which the owner experiences an
electrical incident.
The section is broken into the six following topics: Vehicle vibration
Heat sensitive
Freezing
Water intrusion
Electrical load
Cold or hot start up
Get a thorough description of the incident from the customer . It is important for simulating the conditions of the
problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
Connector & Harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the syst em for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosi on. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
Sensor & Relay
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
Engine Compartment
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
Connectors not fully seated.
Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
Wires laying across brackets or moving components.
Loose, dirty or corroded ground wires.
Wires routed too close to hot components.
To inspect components under the hood, start by verifyi ng the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the syst em is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previous ly explained. Using the wiring diagrams inspect the
wiring for continuity.
Behind the Instrument Panel
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.
