FOREWORD
This manual contains maintenance and repair procedures for NISSAN
PATROL GR,modelY61 series.
In order to assure your safety and the efficient functioning of the vehicle,
this manual should be read thoroughly. It is especially important that the
PRECAUTIONS in the GI section be completely understood before starting
any repair task.
All information in this manual is based on the latest product information
at the time of publication. The right is reserved to make changes in speci-
®cations and methods at any time without notice.
IMPORTANT SAFETY NOTICE
The proper performance of service is essential for both the safety of the
technician and the efficient functioning of the vehicle.
The service methods in this Service Manual are described in such a man-
ner that the service may be performed safely and accurately.
Service varies with the procedures used, the skills of the technician and the
tools and parts available. Accordingly, anyone using service procedures,
tools or parts which are not speci®cally recommended by NISSAN must
®rst completely satisfy himself that neither his safety nor the vehicle's
safety will be jeopardized by the service method selected.

REMOVAL
CAUTION:
+Be careful not to splash brake ¯uid on painted areas; it
may cause paint damage. If brake ¯uid is splashed on
painted areas, wash it away with water immediately.
+ All hoses must be free from excessive bending, twisting
and pulling.
1. Connect vinyl tube to air bleeder valve.
2. Drain brake ¯uid from each air bleeder valve by depressing brake pedal.
3. Remove ¯are nut connecting brake tube and hose, then with- draw lock spring.
4. Cover openings to prevent entrance of dirt whenever discon- necting brake line.
INSPECTION
Check brake lines (tubes and hoses) for cracks, deterioration or
other damage. Replace any damaged parts.
INSTALLATION
CAUTION:
+Re®ll with new brake ¯uid ``DOT 3''.
+ Never reuse drained brake ¯uid.
1. Tighten all ¯are nuts and connecting bolts. Flare nut:
:15-17N zm (1.5 - 1.7 kg-m, 11 - 12 ft-lb)
Connecting bolt:
:17-19N zm (1.7 - 1.9 kg-m, 12 - 14 ft-lb)
2. Re®ll until new brake ¯uid comes out of each air bleeder valve.
3. Bleed air. Refer to ``Bleeding Brake System'', BR-4.
Load Sensing Valve
INSPECTION
CAUTION:
+ Carefully monitor brake ¯uid level at master cylinder.
+ Use new brake ¯uid ``DOT 3''.
+ Be careful not to splash brake ¯uid on painted areas; it
may cause paint damage. If brake ¯uid is splashed on paint
areas, wash it away with water immediately.
+ Depress pedal slowly when raising front brake pressure.
+ Check rear brake pressure 2 seconds after front brake
pressure reaches speci®ed value.
+ For models with ABS disconnect harness connectors from
ABS actuator relay before checking.

Disassembly
1. Bend claws of stopper cap outward.
2. Remove piston stopper while piston is pushed into cylinder(Models with ABS only).
3. Remove piston assemblies.
If it is difficult to remove secondary piston assembly, gradually
apply compressed air through ¯uid outlet.
4. Draw out reservoir tank.
Inspection
Check master cylinder inner wall for pin holes or scratches.
Replace if damaged.
Assembly
1. Insert secondary piston assembly. Then insert primary piston assembly.
+ Pay attention to direction of piston cups in ®gure at left.
Also, insert pistons squarely to avoid scratches on cylin-
der bore.
+ Pay attention to alignment of secondary piston slit with
valve stopper mounting hole of cylinder body (Models with
ABS only).
2. Install stopper cap.
Before installing stopper cap, ensure that claws are bent
inward.
3. Push reservoir tank seals into cylinder body.
4. Push reservoir tank into cylinder body.

Self-diagnosis
FUNCTION
+When a problem occurs in the ABS, the warning lamp on the
instrument panel comes on. To start the self-diagnostic results
mode, ground the self-diagnostic (check) terminal located on
``Data Link Connector for CONSULT''. The location of the mal-
function is indicated by the warning lamp ¯ashing.
+ While DIFF-LOCK is on, anti-lock warning light ¯ashes.
SELF-DIAGNOSIS PROCEDURE
Turn off DIFF-LOCK switch.
Drive vehicle over 30 km/h (19 MPH) for
at least one minute.
Turn ignition switch ``OFF''.
Ground terminal ``4'' of ``Data link con-
nector for CONSULT'' with a suitable har-
ness.
Turn ignition switch ``ON'' while ground-
ing terminal ``4''.
Do not depress brake pedal.
After 3.0 seconds, the warning lamp
starts ¯ashing to indicate the malfunction
code No. (See NOTE.)
Verify the location of the malfunction with
the malfunction code chart. Refer to
BR-48. Then make the necessary repairs
following the diagnostic procedures.
After the malfunctions are repaired, erase
the malfunction codes stored in the con-
trol unit. Refer to BR-47.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have
been erased.
Disconnect the check terminal from the
ground. The self-diagnostic results mode
is now complete.NOTE: The indication terminates
after ®ve minutes.
However, when the ignition
switch is turned from
``OFF'' to ``ON'', the indica-
tion starts ¯ashing again.

. 1: If one or more wheels spin on a rough or slippery road for 40 seconds or more, the ABS warning lamp will illuminate. This does
not indicate a malfunction. Only in the case of the short-circuit (Code Nos. 26, 22, 32 and 36), after repair the ABS warning
lamp also illuminates when the ignition switch is turned ``ON''. In this case, drive the vehicle at speeds greater than 30 km/h (19
MPH) for approximately 1 minute as speci®ed in ``SELF-DIAGNOSIS PROCEDURE'', BR-47. Check to ensure that the ABS
warning lamp goes out while the vehicle is being driven.
