DescriptionNJEC0714SYSTEM DESCRIPTIONNJEC0714S01The ECM and the electronic control fuel injection pump control unit
(abbreviated as the injection pump control unit) perform the real
time communication (signal exchange).
The ECM transmits the signals of the target fuel injection amount,
target fuel injection timing, and engine speed, etc., and receives
the signals of the pump speed and fuel temperature, etc. from the
injection pump control unit.
By those signals, the injection pump controls the optimum fuel
injection amount and injection timing of the spill valve and timing
control valve.
Injection pump control unit has an on board diagnostic system,
which detects malfunctions related to sensors or actuators built-into
electronic control fuel injection pump. These malfunction informa-
tion are transferred through the line (circuit) from injection pump
control unit to ECM.
FUEL INJECTION AMOUNT CONTROLNJEC0714S02In accordance with the target fuel injection amount signal from the
ECM, the injection amount is controlled by controlling the spill valve
in the injection pump and by changing the needle opening time.
FUEL INJECTION TIMING CONTROLNJEC0714S03Based on the target fuel injection timing signal from the ECM, the
injection timing is controlled in accordance with the timer spring by
performing the duty control of the timing control valve in the injec-
tion pump and by adjusting the pressure of the timer piston high
pressure chamber.
FUEL TEMPERATURE SENSORNJEC0714S04The sensor detects the fuel temperature in the injection pump and
calibrates the injection amount change by the fuel temperature.
CAM RING POSITION SENSORNJEC0714S05The sensor detects the passing of the protrusion on the sensor
wheel in the injection pump by the semiconductor magnetic resis-
tance element sensor. The cam ring position sensor synchronizes
with the cam ring, and detects the actual advance amount. The
injection pump control unit measures the injection pump revolution
by the signal of the cam ring position sensor.

InstallationNJBR0146CAUTION:
Refill with new brake fluid “DOT 4”.
Never reuse drained brake fluid.
Do not drain (factory) filled brake fluid from (new) caliper
assemblies.
1. Install caliper assembly.
As shown in the figure, align the piston’s concave to the pad’s
convex, then install the cylinder body to the torque member.
2. Remove the plug from the cylinder body and brake hose.
CAUTION:
Care should be taken as not to let:
Air enter the cylinder body and brake hose.
Brake fluid spill from the cylinder body and brake hose.
3. Install brake hose to caliper securely.
4. Install all parts and secure all bolts.
5. Bleed air. Refer to “Bleeding Brake System”, BR-8.

Cause (condition) -:While driving ooo:Display Driving condition Remarks (correction, etc.)
PlaceIn a parking lot
SEL709V
When driving in a parking lot, or other
location where there are no roads on
the map, matching may place the
vehicle mark on a nearby road. When
the vehicle returns to the road, the
vehicle mark may have deviated from
the correct location.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, and the vehicle
mark may deviate from the correct
location.
If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location
correction and, if necessary,
direction correction. Turn table
SEL710V
When the ignition switch is OFF, the
navigation system cannot get the sig-
nal from the gyroscope (angular speed
sensor). Therefore, the displayed
direction may be wrong and the cor-
rect road may not be easily returned to
after rotating the vehicle on a turn
table with the ignition switch OFF.
Slippery roadsOn snow, wet roads, gravel, or other
roads where tires may slip easily,
accumulated mileage errors may
cause the vehicle mark to deviate from
the correct road.
SlopesWhen parking in sloped garages,
when travelling on banked roads, or in
other cases where the vehicle turns
when tilted, an error in the turning
angle will occur, and the vehicle mark
may deviate from the road.
Map dataRoad not displayed on the map screen
SEL699V
When driving on new roads or other
roads not displayed on the map
screen, map matching does not func-
tion correctly and matches the location
to a nearby road. When the vehicle
returns to a road which is on the map,
the vehicle mark may deviate from the
correct road.
Different road pattern
(Changed due to repair)
ELK0201D
If the road pattern stored in the map
data and the actual road pattern are
different, map matching does not func-
tion correctly and matches the location
to a nearby road. The vehicle mark
may deviate from the correct road.
Vehicle Use of tire chainsWhen tire chains are used, the mile-
age is not correctly detected, and the
vehicle mark may deviate from the
correct road.Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.)
