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 harness connec-
tors.
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 followings:
●Refer to GI-13, "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 followings:
●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

HEADLAMP
HEADLAMP
PFP:26010
System Description EKS003CD
DESCRIPTION
The headlamps are controlled by the lighting switch which is built into the combination switch.
Power is supplied at all times
●to lighting switch terminal 8
●through 15A fuse (No. 40, located in the fuse and fusible link box), and
●to lighting switch terminal 5
●through 15A fuse (No. 41, located in the fuse and fusible link box).
LOW BEAM OPERATION
When the lighting switch is turned to the 2ND position and placed in LOW (“B”) position, power is supplied
●from lighting switch terminal 10
●to terminal 3 of the headlamp LH, and
●from lighting switch terminal 7
●to terminal 3 of the headlamp RH.
Terminal 2 of each headlamp supplies ground through body grounds E24 and E50.
With power and ground supplied, the low beams will illuminate.
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
When the lighting switch is turned to the 2ND position and placed in HIGH (“A”) position or PASS (“C”) posi-
tion, power is supplied
●from lighting switch terminal 6
●to terminal 1 of headlamp RH, and
●from lighting switch terminal 9
●to terminal 1 of headlamp LH, and
●to combination meter terminal 61 (LHD models) or 50 (RHD models) for the HIGH BEAM indicator.
Ground is supplied to terminal 60 (LHD models) or 49 (RHD models) of the combination meter through body
grounds M27 and M70.
Ground is supplied to terminal 2 of each headlamp through body grounds E24 and E50.
With power and ground supplied, the high beams and the HIGH BEAM indicator illuminate.

Trouble Diagnoses
EKS003CF
Aiming Adjustment EKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.
●Keep all tires inflated to correct pressures.
●Place vehicle and tester on one and same flat surface.
●See that there is no-load in vehicle (coolant, engine oil filled up to correct level and full fuel tank) other
than the driver (or equivalent weight placed in driver's position).
