System Description
FUNCTION
Multi-remote control system has the following function.
+Door lock (and set super lock)
+Door unlock (and release super lock)
+Hazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the following two signals must be received.
+Key switch OFF (when ignition key is not in ignition key cylinder.)
+All door switches CLOSED
When the LOCK signal is input to multi-remote control unit (the antenna of the system is combined with multi-
remote control unit), ground is supplied
+through multi-remote control unit terminalj
10
+to super lock control unit terminalj2.
Then super lock control unit operates to lock doors and set super lock.
UNLOCK OPERATION
To unlock door by multi-remote controller, the following signal must be received.
+Key switch OFF (when ignition key is not in ignition key cylinder)
When the UNLOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
+through multi-remote control unit terminalj
11
+to super lock control unit terminalj3.
Then super lock control unit operates to unlock doors and release super lock.
HAZARD REMINDER
When the doors are locked or unlocked by multi-remote controller, ground is supplied
+to terminalj
1of multi-remote control relay-1 and 2
+through multi-remote control unit terminalj
12.
Then the relays are energized and hazard warning lamp ¯ashes as follows
+Lock operation: Flash once
+Unlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRY
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will erase all
ID codes previously entered. Therefore, be sure to receive all remote controllers from the vehicle owner when
any ID code entry is performed.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
+Driver side LOCKED signal (from driver side door unlock sensor)
+Door switch CLOSED signal
+Key switch signal (INSERTED/WITHDRAWN)
+Accessory power supply
+Signal from remote controller
For detailed procedure, refer to ``ID Code Entry Procedure'' in EL-239.

Removal and Installation
CAUTION:
Before removing the front axle assembly, disconnect the ABS
wheel sensor from the assembly. Then move it away from the
front axle assembly area. Failure to do so may result in dam-
age to the sensor wires and the sensor becoming inoperative.
1. Remove free-running hub assembly.
Refer to FRONT AXLE Ð Auto-lock or Manual-lock Free-run-
ning Hub.
2. Remove brake caliper assembly.
Brake hose need not be disconnected from brake caliper.
In this case, suspend caliper assembly with wire so as not to
stretch brake hose.
Be careful not to depress brake pedal, or piston will pop out.
Make sure brake hose is not twisted.
3. Remove ABS sensor.
4. Remove lock washer.
5. Remove wheel bearing lock nut with Tool.
6. Remove wheel hub and wheel bearing.
Be careful not to drop outer bearing.
7. After installing wheel hub and wheel bearing, adjust wheel
bearing preload.
Refer to ``Front Wheel Bearing'', ``ON-VEHICLE SERVICE'',
FA-5.

8. Separate brake disc to hub.
Inspection
Thoroughly clean wheel bearings and wheel hub.
WHEEL BEARING
+Make sure wheel bearing rolls freely and is free from noise,
crack, pitting or wear.
WHEEL HUB
+Check wheel hub for crack by using a magnetic exploration or
dyeing test.
Assembly
1. Install bearing outer race with Tool until it seats in hub.
2. Install the sensor rotor using suitable drift and press. (Models
with ABS)
Always replace sensor rotor with new one.
Pay attention to the direction of front sensor rotor as shown in
®gure.
3. Pack multi-purpose grease to hub and hub cap.

Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
Precaution for Supplemental Restraint System
(SRS) ``AIR BAG'' and ``SEAT BELT
PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and
``SEAT BELT PRE-TENSIONER'' used along with a seat belt, helps
to reduce the risk or severity of injury to the driver and front pas-
senger in a frontal collision. The SRS system composition which is
available to NISSAN MODEL Y61 is as follows (The composition
varies according to the destination.):
Driver air bag module (located in the center of the steering wheel),
front passenger air bag module (located on the instrument panel on
passenger side), seat belt pre-tensioner, a diagnosis sensor unit,
warning lamp, wiring harness and spiral cable.
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 in¯ation, all main-
tenance must be performed by an authorized NISSAN
dealer.
+Improper maintenance, including incorrect removal and
installation of the SRS, can lead to personal 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.
Spiral cable and wiring harnesses are covered with yellow
insulation either just before the harness connectors or for
the complete harness are related to the SRS.
SGI646
PRECAUTIONS
GI-1

+Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
+Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
+Replace inner and outer races of tapered roller bearings and
needle bearings as a set.
+Arrange the disassembled parts in accordance with their
assembled locations and sequence.
+Do not touch the terminals of electrical components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.
+After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.
+Use only the ¯uids and lubricants speci®ed in this manual.
+Use approved bonding agent, sealants or their equivalents
when required.
+Use tools and recommended special tools where speci®ed for
safe and efficient service repairs.
+When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
+Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do
not carelessly disconnect the harness connectors which are
related to the ECCS system and TCM (Transmission Control
Module) system. The connectors should be disconnected only
when working according to the WORK FLOW of TROUBLE
DIAGNOSES in EC and AT sections.
Precautions for Multiport Fuel Injection System
or ECCS Engine
+Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ``OFF'' position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
+
Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
+Be careful not to jar components such as ECM and mass air
¯ow sensor.SGI787
