2001 NISSAN ALMERA warning

Trouble DiagnosesNJSC0011Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspec-
tion Table.
+Before starting, inspect the fusible link.
+Use fully charged battery.
WITH IC REGULATORNJSC0011S01
SEL338V
NOTE:
+If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque.)
+When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary, replace faulty
parts with new ones.
MALFUNCTION INDICATORNJSC0011S02The IC regulator warning function activates to illuminate ªCHARGEº warning lamp, if any of the following
symptoms occur while alternator is operating:
+Excessive voltage is produced.
+No voltage is produced.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NJST0044The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to NISSAN MODEL N16 is as follows (The compo-
sition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To 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 should be per-
formed by an authorized NISSAN dealer.
+Improper 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 RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except ªSEAT BELT PRE-TENSIONERº connector) can be
identified by yellow harness connector.
Precautions for Steering SystemNJST0003+Before disassembly, thoroughly clean the outside of the unit.
+Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
+Place disassembled parts in order, on a parts rack, for easier and proper assembly.
+Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
+Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable
solvent.
+Before assembly, apply a coat of recommended power steering fluid* to hydraulic parts. Vaseline
may be applied to O-rings and seals. Do not use any grease.
+Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.

Rack sliding force (Sedan only):
Not more than 294 N (30 kg, 66 lb)
Maximum force deviation:
147 N (15 kg, 33 lb)
6. If rack sliding force is not within specification, overhaul steer-
ing gear assembly.
7. If rack sliding force is OK, inspect steering column. Refer to
ST-14.

Checking Hydraulic SystemNJST0016Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to ªBleed-
ing Hydraulic Systemº, ST-8.
2. Run engine at idle speed or 1,000 rpm.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, fluid pressure in oil pump
increases to maximum. This will raise oil temperature abnor-
mally.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Oil pump maximum standard pressure:

8,800 - 9,400 kPa (88.0 - 94.0 bar, 88.7 - 95.8
kg/cm
2, 1,261 - 1,362 psi)
+If pressure reaches maximum operating pressure, system is
OK.
+If pressure increases above maximum operating pressure,
check power steering pump flow control valve. Refer to ST-25.
4. If power steering pressure is below the maximum operating
pressure, slowly close shut-off valve and check pressure
again.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
+If pressure increases to maximum operating pressure, gear is
damaged. Refer to ªRemoval and Installationº, ST-17.
+If pressure remains below maximum operating pressure, pump
is damaged. Refer to ªDisassemblyº, ST-26.
5. After checking hydraulic system, remove Tool and add fluid as
