CHARGING SYSTEM

Trouble DiagnosisEKS00319
Before performing an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Ta b l e .

Before starting, inspect the fusible link.

Use fully charged battery.
WITH IC REGULATOR
NOTE:

If the inspection result is OK even though the charging system is malfunctioning, check the “B” terminal
connection. (Check the tightening torque and voltage drop.)

Check condition of rotor coil, rotor slip ring, brush and stator coil. If necessary, replace malfunctioning
parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

PRECAUTION

PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS0079M
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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.
Precaution EKS003KS

Do not touch the glass of bulb directly by hand. Keep grease and other oily matters away from it. Do not
touch bulb by hand while it is lit or right after being turned off. Burning may result.

Do not leave bulb out of headlamp reflector for a long time because dust, moisture smoke, etc. may affect
the performance of the headlamp. When replacing the bulb, be sure to replace it with a new one.

Adjust aiming by tightening aiming screw. (To adjust it toward loosening side, first loosen adjusting screw,
and then make adjustment by tightening.)

To remove soil or sealant of bulbs, do not use organic solvent (thinner, gasoline, etc.)

When replacing bulb, be sure to hold bulb socket and pull it out straight. If wiring harness of the bulb is
pulled at an angle, the bulb may be caught in the lamp, making it difficult to take out.
Wiring Diagrams and Trouble Diagnosis EKS003KT
When you read wiring diagrams, refer to the following:

Refer to GI-14, "How to Read Wiring Diagrams" in GI section

Refer to PG-2, "POWER SUPPLY ROUTING" for power distribution circuit in PG section
When you perform trouble diagnosis, refer to the following:

Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section

Refer toGI-23, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section

WARNING:

Xenon headlamp has a high-tension current generating area. Be extremely careful when removing
and installing. Be certain to disconnect battery negative cable prior to removing or installing.

When xenon headlamp is lit, never touch harness (covered with red or amber insulation), bulb
itself or bulb socket with your bare hands

Never service a xenon headlamp with wet hands.

When checking body side harness with a circuit tester, be certain to disconnect harness connec-
tor from xenon headlamp.

When xenon headlamp is lit, xenon bulb must be installed in headlamp housing. (Never turn on
xenon headlamp, if bulb is out of headlamp housing.)
CAUTION:
Make sure to install bulb securely; if xenon bulb is improperly installed in its socket, high-tension cur-
rent leaks occur. This may lead to a melted bulb and/or bulb socket.

LH high beam does not operate, but
LH low beam operates.1. Bulb
2. Open in high beam LH circuit
3. Lighting switch
4. Headlamp LH ground circuit1. Check bulb.
2. Check the following.
–Harness between headlamp LH and lighting switch for
open circuit.

LH low beam does not operate, but
LH high beam operates.1. 20A fuse
2. HID relay LH
3. Open in LH low beam circuit
4. LH low beam ground circuit
5. Xenon bulb
6. HID control unit1. Check 20A fuse (No52, located in fuse and fusible link
box). Verify battery positive voltage is present at terminal
5 of HID relay LH.
2. Check HID relay LH.
3. Check harness between HID relay LH terminal 3 and
headlamp LH terminal 2 for an open circuit.
4. Check harness between headlamp LH and ground.
