Condition NISSAN TERRANO 2002 Service Repair Manual

SETTING THE THEFT WARNING SYSTEM
Initial condition
(1) Close all doors.
(2) Close hood.
Pre-armed phase and armed phase
The theft warning system turns into the ªpre-armedº phase when hood and all doors are closed and locked by
key or multi-remote controller. (The security indicator lamp blinks intermittently for 30 seconds.)
After about 30 seconds, the system automatically shifts into the ªarmedº phase (the system is set).
CANCELING THE SET THEFT WARNING SYSTEM
When the following (a) or (b) operation is performed, the armed phase is canceled.
(a) Unlock the doors with the multi-remote controller.
(b) Insert key in ignition key cylinder and turn it to ON. Then NATS IMMU will send a disarm signal to the time
control unit.
ACTIVATING THE ALARM OPERATION OF THE THEFT WARNING SYSTEM
Make sure the system is in the armed phase. When the following operation (a) (b) (c) or (d) is performed, the
system sounds the horns and flashes the hazard lamp for about 30 seconds.
(a) Engine hood or any door is opened before unlocking door with the multi-remote controller.
(b) A door is unlocked without using the multi-remote controller.
(c) The ignition is switched ON without using a NATS registered key.
(d) The ultrasonic sensing is triggered.

INITIAL CONDITION TO ARM THE SYSTEM
The operation of the theft warning system is controlled by all the doors and hood.
To activate the theft warning system, the time control unit must receive signals indicating all the doors and
hood are closed and the doors are locked.
When a door is open, time control unit terminal
U06orU07receives a ground signal from each door switch.
When a door is unlocked, time control unit terminal
U25,U35orU36receives a ground signal from each door

1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC section, ªFuel Pressure
Releaseº.
IDo not disconnect CONSULT-II until the end of this operation;
it will be used to check engine rpm and for error detection at
the end of this operation.
4. Disconnect the negative battery terminal.
5. Remove the following parts.
IIntercooler
IThrottle body
IRocker cover
6. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT A/T (15A)] from fuse box
on the right side of engine compartment.
7. Remove glow plugs from all the cylinders.
IBefore removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
ICarefully remove glow plugs to prevent any damage or
breakage.
IHandle with care to avoid applying any shock to glow
plugs.
8. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.
:15-19N×m (1.5 - 2.0 kg-m, 11 - 14 ft-lb)
9. Connect battery negative terminal.
10. Set the ignition switch to ªSTARTº and crank. When gauge
pointer stabilizes, read compression pressure and engine rpm.
Repeat the above steps for each cylinder.
IAlways use a fully-charged battery to obtain specified
engine speed.

IWhen engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
IIf engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cylinder
head gaskets, piston rings, pistons, cylinder bores, cylinder
block upper and lower surfaces) and measure again.
11. Complete this operation as follows:
a. Turn the ignition switch to ªOFFº.
b. Disconnect battery negative terminal.
c. Replace glow plug oil seals and install glow plugs.
d. Install fuel injection pump fuse [ENG CONT A/T (15A)].
e. Connect battery negative terminal.
f. Using CONSULT-II make sure no error code is indicated for
items of self-diagnosis. Refer to EC section, ªTrouble Diagno-
sis Ð Indexº.

Removal
1. Remove the engine assembly.
Refer to ªENGINE REMOVALº, EM-63.
2. Place the engine on an engine stand (SST).
Refer to ªCYLINDER BLOCKº, EM-67.
3. Remove the following.

4. Remove the chain cover, timing chain and other parts in con-
nection.
Before removing timing chain, remove injection pump sprocket
with No. 1 cylinder being positioned at TDC. Refer to the fig-
ure. Refer to ªTIMING CHAINº, EM-26.
CAUTION:
After removing timing chain, never rotate crankshaft, or the
piston will push the valve up and damage the valve.
IDo not paint the match mark on the timing chain beforehand as
the No. 1 cylinder is set at the TDC during assembly.
5. Remove the TDC sensor.
CAUTION:
IDo not drop or hit the sensor.
IStore in a clean place free of iron filings, etc.
IDo not place near any magnetic equipment.
6. Remove the water pump.
Refer to ªWATER PUMPº in LC section.
7. Remove the water inlet.

12. Remove the idler gears (A) and (B).
ICheck the backlash of each gear before removing. Refer to
ªBACKLASH OF EACH GEARº, ªInspectionº.
CAUTION:
IDo not loosen the internal mechanism setting bolt of the
idler gear (A). (The idler gear cannot be reused when the
internal mechanism is released.)
IDuring removal of the idler gears (A) and (B), do not face
the rear side downward as the idler shaft will drop.
13. Set the fuel injection timing gear with the pulley holder (SST).
14. Remove injection pump timing gear.
15. Extract the balancer shaft taking care not to damage the inner
bushes of the cylinder block.
16. Remove the fuel injection pump.
17. Remove the front plate.
Inspection
BACKLASH OF EACH GEAR
Method using a fuse wire
ITighten the holding bolts of each gear to specification.
IPlace a wire in the biting area of the teeth between the gears
to be checked, rotate the crankshaft in the operating direction
so that the wire is taken inwards.
IMeasure the crushed area of the wire with a micrometer.
Method using dial gauge
ITighten the holding bolts of each gear to specification.
IPlace the dial gauge on the tooth surface area of the gear to
be checked.
IWith the other gear in a set position, measure the dial gauge
value while moving the gear left and right.
Standard: 0.07 - 0.11 mm (0.0028 - 0.0043 in)
Limit: 0.20 mm (0.0079 in)
IIf it exceeds the limit, replace the gear and measure again.
IIf it exceeds the limit again, check for the installation condition
of the gear driving parts, wear of shaft and gear, and oil clear-
ance.
