Filament CheckEIS005Z4
1. When measuring voltage, wrap tin foil around the top of the neg-
ative probe.Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of each filament.
3. If a filament is burned out, circuit tester registers 0 or battery voltage.
4. To locate burned out point, move probe to left and right along fil- ament. Test needle will swing abruptly when probe passes the
point.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
UKS0017I
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 When Using CONSULT-IIUKS0017J
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
–If YES, GO TO 2.
–If NO, GO TO 5.
2. Is there any indication other than indications relating to CAN communication system in the self-diagnosis results?
–If YES, GO TO 3.
–If NO, GO TO 4.
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica- tion. Therefore, erase the self-diagnosis results.
5. Diagnose CAN communication system. Refer to LAN-5, "
TROUBLE DIAGNOSES WORK FLOW" .
Precautions For Trouble DiagnosisUKS0017K
CAN SYSTEM

Do not apply voltage of 7.0 V or higher to the measurement terminals.

Use the tester with its open terminal voltage being 7.0 V or less.

Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.

TROUBLE DIAGNOSES WORK FLOWPFP:00004
When Displaying CAN Communication System ErrorsUKS004SS
WHEN A MALFUNCTION IS DETECTED BY CAN COMMUNICATION SYSTEM

CAN communication line is open. (CAN H, CAN L, or both)

CAN communication line is shorted. (Ground, between CAN lines, or other harnesses)

The areas related to CAN communication of unit is malfunctioning.
WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM

Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).

Fuse blown out (removed): CAN communication of the unit may be stopped at such time.

Low voltage: If the voltage decreases because of battery discharge when IGN is ON, malfunction may be
detected by self-diagnosis according to the units.
