Note in the illustration that there is an excessi ve 4.1 volt drop between the battery and the bulb.
Measuring Voltage Drop — Step-by-Step
• The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those
in “Computer Controlled Systems”).
• Circuits in the “Computer Controll ed System” operate on very low amperage.
• The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the
system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corrosion.
• The step by step voltage drop test can identify a component or wire with too much resistance.
CONTROL UNIT CIRCUIT TEST
System Description
• When the switch is ON, the control unit lights up the lamp.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
INPUT-OUTPUT VOLTAGE CHART
• The voltage value is based on the body ground.
• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltag e. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to ligh t up the
lamp.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to “sleep mode”, potentiall y causing a discharged battery and a no-start condition.
NOTE:
This vehicle is diagnosed using the CONSULT-III plus.
• When CONSULT is connected with a data link connector equipped on the vehicle side, it will communicate with the control unit
equipped in the vehicle and then enable various kinds of diagnos-
tic tests.
• Refer to “CONSULT-III plus Operation Manual” for more informa- tion.

CONSULT CHECKING SYSTEM
If the CONSULT cannot diagnose the system properly, check the following items.
NOTE:
The DDL2 circuits and CAN communication lines from DLC pins 6, 7 and 14 may be connected to more than
one system. A short in a DDL circuit or CAN lines c onnected to a control unit in one system may affect CON-
SULT access to other systems. For a complete DDL circuit layout, refer to GI-38, "Wiring Diagram"
. For a com-
plete CAN line layout, refer to LAN-36, "Wiring Diagram"
.
Symptom Check item
CONSULT cannot access any
system. • CONSULT DLC power supply circuit (Terminal 8 and 16) and ground circuit (Terminal 4 and 5)
CONSULT cannot access indi-
vidual system. (Other systems
can be accessed.) • Power supply and ground circuit for the control unit of the system (For detailed circuit, refer to wiring
diagram for each system.)
• Open or short circuit between the system and CONSULT DLC (For detailed circuit, refer to wiring diagram for each system.)
• Open or short circuit CAN communication line. Refer to LAN-18, "Trouble Diagnosis Flow Chart"
.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951564
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
Procedure without Cowl Top CoverINFOID:0000000009463652
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Handling for Adhe sive and PrimerINFOID:0000000009463653
• Do not use an adhesive which is past its usable date. Shel f life of this product is limited to six months after
the date of manufacture. Carefully adhere to the ex piration or manufacture date printed on the box.
• Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.
• Open the seal of the primer and adhesive just before application. Discard the remainder.
• Before application, be sure to shake the primer container to stir the contents. If any floating material is found,
do not use it.
• If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with
soap.
• When using primer and adhesive, always observe the precautions in the instruction manual.
Precaution for WorkINFOID:0000000009463654
• When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.

• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty
area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.
