2004 NISSAN PATROL sensor

THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA
The navigation system moves the current location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN
THE RIGHT PLACE AND SOMETIMES IT IS THE WRONG PLACE
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW
+The map matching function needs to refer to the data of the surrounding area. It is necessary to drive some
distance for the function to work.
+ Because map matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be corrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION
+The GPS accuracy has an error of about 10 m (30 ft). In some cases the current location mark may not
be on the correct street, even when GPS location correction is done.
+ The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.
+ GPS location correction may not be performed when the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF THE DISPLAY DIFFER FOR THE BIRDVIEW TAND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW Tscreen from the ¯at map screen are as follows.
+ The current place name displays names which are primarily in the direction of vehicle travel.
+ The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(¯at) map display.
+ The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
+ Some thinning of the character data is done to prevent the display becoming to complex. In some cases
and in some locations, the display contents may differ.
+ The same place name, street name, etc. may be displayed multiple times.

Features (TB48 Engine Models)
CAN COMMUNICATION SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many
electronic control units are equipped onto a vehicle, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected with
2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wir-
ing. Each control unit transmits/receives data but selectively reads required data only.
SYSTEM CONSTRUCTION
Magnet clutch control
When A/C switch is pressed, turn fan control dial to ON or set mode control dial to DEF position, A/C auto
amp. inputs compressor ON signal to ECM.
ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant pressure sen-
sor signal, throttle angle, etc.).
When sending compressor ON signal to ECM from A/C auto amp., ECM simultaneously sends compressor
feedback signal to uni®ed meter C/U via CAN communication line.
Uni®ed meter control unit sends compressor feedback signal to A/C auto amp. Then, A/C auto amp. uses input
compressor feedback signal to control air inlet.

Self-diagnosis
INTRODUCTION AND GENERAL DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. by system line.
Self-diagnosis is step-1 to 7. There are two ways of changing method during self-diagnosis.
+Switching to self-diagnosis step-1 to 4.
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing A/C switch for at least 5 seconds. The A/C switch must
be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system will be
canceled by either pressing intake switch or turning the ignition switch OFF. Shifting from one step to
another is accomplished be means of turning fan control dial, as required.
+Switching to self-diagnosis step-5 to 7 (Auxiliary mechanism).
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing intake switch for at least 5 seconds. The intake switch
must be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system
will be canceled by either pressing A/C switch or turning the ignition switch OFF. Shifting from one step
to another is accomplished by means of turning fan control dial, as required.
