CAN Communication System DescriptionEIS00DX1
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.
CAN Communication UnitEIS00DX2
Refer toLAN-23, "CAN COMMUNICATION".

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006DL
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:
lTo 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.
lImproper 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.
lDo 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 for Brake SystemEFS005SD
lClean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed
on painted areas, wash it away with water immediately.
lTo clean or wash all parts of master cylinder, disc brake caliper, wheel cylinder, use new brake fluid.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse a flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
lAlways tighten brake lines to the specified torque when install-
ing.
lBefore working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
the battery cables.
lBurnish the new brake surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer toBR-29, "
BRAKE BURNISHING PROCEDURE".
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.SBR820BA
