Precautions for brake controlEFS001B7
lIf malfunction is indicated by 4WD warning lamp and/or ABS warning lamp, collect necessary information
from customer (what symptoms are present under what conditions). Find out possible causes before start-
ing service. Besides electrical system inspection, check operation of ABS actuator.
lIf malfunction is detected, proceed to trouble diagnosis after checking tire pressure and tire wear.
lStopping distance or steering stability may be deteriorated by the following conditions. Tire size and type
are in improper combination. Brake pads are not Nissan genuine parts.
lFitting tires of different size on vehicle can be cause of longitudinal vibration. Always use tires of the same
size and brand. Exchange front and rear tires on the following conditions: Longitudinal vibration occurs in
vehicle with tires of the same size and brand. After replacement, perform trouble diagnosis. 1580|None
l4WD/ABS function may have a failure or error under following condition: There is radio, antenna, or
antenna lead-in wire (including wiring) near control module.
lIf aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check electrical har-

PRECAUTIONS
[ESP/TCS/ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS0019N
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.
WAR NIN G:
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 harness connector.
Precautions for Brake SystemEFS0019O
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.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of hydraulic system.
lUse flare nut wrench when removing and installing brake tubes.
lAlways torque brake lines when installing.
lBefore working, turn the ignition switch OFF and disconnect the
connectors for the ESP/TCS/ABS actuator and control unit or
the battery terminals.
lBurnish the brake contact 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-10, "
Brake Burnishing
Procedure".
WAR NIN G:
Clean brakes with a vacuum dust collector to minimize risk
of health hazard from powder caused by friction.
Precautions for Brake ControlEFS0019P
lDuring the EPS/TCS/ABS operation, the brake pedal vibrates lightly and its mechanical noise may be
heard. This is a normal condition.
lJust after starting the vehicle after ignition switch ON, the brake pedal may vibrate or the motor operating
noise may be heard from the engine compartment. This is a normal status of the operation check.
lThe stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough,
gravel, or snowy (fresh deep snow) road.
lIf a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary infor-
mation from the customer (what symptoms are present under what conditions) and find out the possible
causes before starting the service. Besides the electrical system inspection, check the booster operation,
brake fluid level, and oil leaks.
lIf the tire size and type are used in a improper combination, or the brake pads are not NISSAN genuine
parts, the stopping distance or steering stability may deteriorate.
lIf there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, the ESP/TCS/
ABS function may have a malfunction or error.
lIf aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check the electrical har-
nesses for pinches, open, and improper wiring.
