NOTE:
If DTC U1000 or U1001 is displayed, first perform the trouble diagnosis for DTC U1000, U1001. Refer to
EC-492, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
The vehicle speed signal is sent from vehicle speed sensor (models with ABS) or ABS actuator and electric
unit (control unit) (models with ABS) to combination meter. The combination meter then sends a signal to the
ECM through CAN communication line.
Diagnostic ProcedureEBS00KLF
1.CHECK VEHICLE SPEED SIGNAL OVERALL FUNCTION
With CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Select “VHCL SPEED SE” in “DATA MONITOR” mode with
CONSULT-II.
4. Make sure that “VHCL SPEED SE” indication exceeds 10 km/h
(6 MPH) when rotating wheels with suitable gear position.
Without CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Read vehicle speed with combination meter.
Make sure that vehicle speed indication exceeds 10 km/h (6 MPH) when rotating wheels with suitable
gear position.

CAN COMMUNICATIONPFP:23710
System DescriptionECS007O2
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS001YP
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.
Precautions for Working with HFC-134a (R-134a)EJS001YQ
WARNING:
●Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor malfunction is likely to occur.
●The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
–When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
–When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possi-
ble to minimize the entry of moisture into system.
–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. Without proper sealing, lubricant will become moisture saturated and should not be used.
–Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meet-
ing requirements of SAE J2210 HFC-134a (R-134a) recycling equipment, or J2209 HFC-134a (R-
134a) recovery equipment. If accidental system discharge occurs, ventilate work area before
resuming service. Additional health and safety information may be obtained from refrigerant and
lubricant manufacturers.
–Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts.
Damage may result.
General Refrigerant PrecautionsEJS001YR
WARNING:
●Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
●Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
●Do not store or heat refrigerant containers above 52°C (125°F).
●Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
●Do not intentionally drop, puncture, or incinerate refrigerant containers.
●Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
●Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
●Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
