lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.
lTo clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.

lBefore working, turn OFF ignition switch. Disconnect connectors
for ABS actuator and control module or battery terminals.
WAR NIN G:
lClean brake pads and shoes with a waste cloth, then wipe

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-
nesses for pinches, open, and improper wiring.

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.

Basic InspectionEFS001A9
PRELIMINARY CHECK 1: (BRAKE FLUID LEVEL AND LEAK INSPECTION)
1. Check the fluid level in the brake reservoir tank. If the fluid level is low, refill the brake fluid.
2. Check the area around the brake piping, ESP/TCS/ABS actuator for leaks. If a leak or oozing is detected,
checkasfollows:
lIf the connections at the ESP/TCS/ABS actuator are loose, tighten the piping to the specified torque.
Then check again for leaks, and make sure that there is no fluid leak.
lIf the flare nuts at the connections and the threads of the ESP/TCS/ABS actuator are damaged, replace
the damaged parts. Then check again for leaks, and make sure that there is no fluid leak.
lIf a leak or oozing is detected on other parts than the ESP/TCS/ABS actuator connections, wipe the
applicable part with a clean cloth. Then check again for leaks, and if there is still a leak or oozing,
replace the damaged part.
lIf a leak or oozing is detected on the ESP/TCS/ABS actuator body, wipe the applicable part with a clean
cloth. Then check again for leaks, and if there is still a leak or oozing, replace the ESP/TCS/ABS actua-
tor body.
CAUTION:
Do not disassemble the actuator body.
3. Check the brake disc rotor and pads.
PRELIMINARY CHECK 2: (INSPECTION FOR LOOSE POWER SUPPLY TERMINAL)
Check the battery for looseness on the battery positive/negative terminals and ground connection. If loose-
ness is detected, tighten the piping to the specified torque. Check that the battery voltage does not drop and
the alternator is normal.
PRELIMINARY CHECK 3: (INSPECTION FOR ABS WARNING LAMP, ESP OFF INDICATOR
LAMP, AND SLIP INDICATOR LAMP)
1. Check that the ABS warning lamp is ON for Approx. 0.5 seconds when the ignition switch is turned ON. If
it does not turn on, check the ABS warning lamp and the circuit, and the combination meter.
2. Check that ESP OFF indicator lamp is ON for Approx. 0.5 seconds when the ignition switch is turned ON.
If it does not turn ON, check the ESP OFF indicator lamp and the circuit, and the combination meter.
3. Check that the SLIP indicator lamp is ON for Approx. 0.5 seconds when the ignition switch is turned ON. If
it does not turn ON, check the SLIP indicator lamp and the circuit.
