Checking Brake Fluid LevelEFS000C5
lConfirm reservoir tank fluid level is within specifications
(between MAX and MIN lines).
lVisually check around reservoir tank for fluid leaks.
lIf fluid level is excessively low, check brake system for leaks.
lIf warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Checking Brake LineEFS001C5
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tube and hoses) for cracks, deterioration or
other damage. Replace and damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake FluidEFS000C3
CAUTION:
lRefill with new brake fluid “DOT 3 or DOT 4”.
lAlways keep fluid level higher than minimum line on reservoir tank.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on spill or splash on painted areas; it may cause paint damage.
If brake fluid is splashed on painted areas, wash it away water immediately.
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel
while depressing the brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

PRECAUTIONS
[4WD/ABS]PRECAUTIONSPFP:00001
Precautions for brake systemEFS001B6
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.
lTo clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing and installing brake tube.
lAlways torque brake lines when installing.
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".
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
with a dust collector.
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.

ALL MODE 4X4 SYSTEM
PFP:47850
System DescriptionEFS001CJ
ABS FUNCTION
lDuring ABS operation, brake pedal lightly vibrates and its mechanical noise may be heard. This is a nor-
mal condition.
lWhen starting engine, or just after starting vehicle, brake pedal may vibrate. Also motor operating noise
may be heard from engine compartment. This is a normal status of operation check.
lWhen vehicle drives on rough, gravel, or snowy (fresh deep snow) road, the following conditions occur.
Stopping distance may be longer than that of vehicles without ABS.
4WD FUNCTION
lElectronically controlled 4WD is controlled by the same control module as that for ABS (4WD/ABS control
unit). 4WD/ABS control unit controls both electronically-controlled 4WD and ABS, based on input signals
from several sensors.
lIf electrical system-related malfunction occurred in 4WD/ABS system, control unit illuminates the following
lamps: 4WD warning lamp and/or ABS warning lamp on meter control unit assembly. This notifies driver of
malfunction. At the same time, control unit indicates malfunctioning part detected by self-diagnosis with
flashing pattern of LED. Indication on electronic system diagnosis tester (CONSULT) corresponds to this
flashing pattern as shown below.

TROUBLE DIAGNOSISPFP:00004
Fail-safe FunctionEFS001BB
lIf a malfunction occurs in 4WD/ABS electrical system, and control unit detects the malfunction, 4WD
warning light on gauge turns ON to inform driver of system malfunction.
lWhen 4WD and ABS warning lamp is ON, vehicle is in 2WD.
How to Proceed with Trouble DiagnosisEFS001BC
BASIC CONCEPT
lThe most important point to perform trouble diagnosis is to understand vehicle systems (control and
mechanism) thoroughly.
lIt is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptom, and understand it fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptoms by driving vehicle with
customer.
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like “maybe the customer means that...,” or
“maybe the customer mentions this symptom”.
lIt is essential to check symptoms right from the beginning in
order to repair a malfunction completely.
For intermittent malfunction, reproduce symptom based on inter-
view with customer and past examples. Do not perform inspec-
tion on ad hoc basis. Most intermittent malfunctions are caused
by poor contacts. In this case, it will be effective to shake sus-
pected harness or connector by hand. When repairing without
any symptom diagnosis, you can not judge if malfunction has
actually been eliminated.
lAfter completing diagnosis, always erase diagnostic memory.
Refer toBRC-23, "
CONSULT-II Functions".
lFor intermittent malfunction, move harness or harness connector by hand. Then check poor contact or
false open circuit.
lAlways read “GI General Information” to check general to confirm general precautions.
