SEAT BELT RETRACTOR OFF-VEHICLE INSPECTION
1. Remove the seat belt retractor assembly.
2. Slowly pull out webbing while tilting the retractor assembly forward from the mounted position without
twisting the retractor assembly as shown in the figure.
If NG, replace the retractor assembly.15 degrees or less tilt : Webbing can be pulled out.
35 degrees or more tilt : Webbing locks and cannot be pulled out.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS00794
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.
Wiring Diagrams and Trouble DiagnosisAKS00796
When you read wiring diagrams, refer to the following:

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 following:

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.

DIAGNOSTIC PROCEDURE 4
Check “B” Terminal Circuit
1. CHECK “B” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check to see if “B” terminal is clean and tight.
OK or NG
OK >> GO TO 2. Confirm repair by performing complete Battery/Starting/Charging system test.
NG >> Repair “B” terminal connection.
2. CHECK ALTERNATOR “B” TERMINAL CIRCUIT
Check voltage between alternator B terminal E307 terminal 1 (B/R)
and ground using a digital circuit tester.
OK or NG
OK >> GO TO 3.
NG >> Check the following.

120A fusible link [fusible link holder (VK45DE and
VQ35DE AWD)]

Harness for open or short between alternator and fus-
ible link (VK45DE and VQ35DE AWD)

Harness for open or short between alternator and battery (VQ35DE 2WD)
3. CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start the engine.
2. When the engine running at idle and warm, check voltage
between alternator B terminal E307 terminal 1 (B/R) and battery
positive terminal using a digital circuit tester.
OK or NG
OK >> GO TO 4.
NG >> Check harness between the battery and the alternator
for poor continuity.
4. CHECK ALTERNATOR DRIVE BELT TENSION
1. Turn ignition switch OFF.
2. Check alternator drive belt tension. Refer to EM-169, "
Checking Drive Belts" (VK45DE) or EM-15,
"Checking Drive Belts" (VQ35DE) in “ENGINE MECHANICAL (EM)” section.
YES or NO
YES >> Replace the alternator. Confirm repair by performing complete Battery/Starting/Charging system
test.
NO >> Readjust drive belt tension. Refer to EM-169, "
Tension Adjustment" (VK45DE) or EM-15, "Te n -
sion Adjustment" (VQ35DE) in “ENGINE MECHANICAL (EM)” section. Battery voltage should exist.
