Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or Varies

AKS004GI

1. 

CHECK FUEL GAUGE FLUCTUATION

Test drive vehicle to see if gauge fluctuates only during driving or before or after stopping.
Does the indication value vary only during driving or before or after stopping?

YES

>> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.

NO

>> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble

diagnosis.

Fuel Gauge Does Not Move to Full-position

AKS004GJ

1. 

QUESTION 1

Does it take a long time for the pointer to move to full-position?

YES or NO

YES

>> GO TO 2.

NO

>> GO TO 3.

2. 

QUESTION 2

Was the vehicle fueled with the ignition switch ON?

YES or NO

YES

>> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move

to full-position because of the characteristic of the fuel gauge.

NO

>> GO TO 3.

3. 

QUESTION 3

Is the vehicle parked on an incline?

YES or NO

YES

>> Check the fuel level indication with vehicle on a level surface.

NO

>> GO TO 4.

4. 

QUESTION 4

During driving, does the fuel gauge pointer move gradually toward empty-position?
YES or NO

YES

>> Check the fuel level sensor unit. Refer to 

DI-28, "FUEL LEVEL SENSOR UNIT CHECK"

 .

NO

>> The float arm may interfere or bind with any of the components in the fuel tank.

System Description

AKS004GN

●

For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.

●

Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to 

ATC-25, "AIR CONDITIONER CONTROL"

  in ATC section.

●

Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.

●

And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.

●

Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.

●

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) or display control unit (with NAVI)
using CAN communication.

●

The unified meter and A/C amp. have a CONSULT-II function (self-diagnostic results, CAN diagnostic
support monitor, data monitor).

CAN Communication System Description

AKS004GO

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 elec-
tronic 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 wiring.
Each control unit transmits/receives data but selectively reads required data only.

With the ignition switch OFF, connect “CONSULT-II” and “CON-
SULT-II CONVERTER” to the data link connector, then turn igni-
tion switch ON.

2.

Touch “START (NISSAN BASED VHCL)”.

3.

Touch “METER A/C AMP” on “SELECT SYSTEM” screen. If
“METER A/C AMP” is not indicated, go to 

GI-39, "CONSULT-II

SELF-DIAGNOSTIC RESULTS
Operation Procedure

1.

Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.

2.

Self-diagnosis results are displayed.

Display Item List

“TIME” indicates the condition of the self-diagnosis results judged by each signal input.

●

Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.

●

Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.

After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1”

→

“2”

→

“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-

noses will be erased. And if any malfunction is detected again, “0” will be indicated.

CAUTION:

“TIME” keeps showing “0” after returning to normal condition only in the case that incident history of
“CAN COMM CIRC [U1000]” remains because of low tire pressure warning control unit, display control
unit (with NAVI) or display unit (without NAVI) malfunction.

DATA MONITOR
Operation Procedure

1.

Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.

2.

Touch either “MAIN SIGNALS” or “SELECTION FROM MENU” on the “DATA MONITOR” screen.

3.

When “SELECTION FROM MENU” is selected, touch individual items to be monitored. When “MAIN SIG-
NALS” is selected, main items will be monitored.

System Description

AKS00ABY

This unit displays earth magnetism and heading direction of vehicle.

DIRECTION DISPLAY

Push the switch when the ignition key is in the “ON” or “START” position. The direction will be displayed.
Pushing the “COMP” switch a second time will turn off the display.

1.

If the display reads “C” calibrate the compass by driving the vehicle in 3 complete circles at less than 8
km/h (5 MPH).

2.

To adjust for compass variance:

a.

Press the “COMP” switch for more than 3 seconds. The current zone number will appear in the display.

b.

Find your current location and variance zone number on the zone map.

c.

Press the “COMP” switch until the new zone number appears in the display. After you stop pressing the
button in, the display will show a compass direction within a few seconds.

NOTE:
1. Do not install the ski rack, antenna, etc. which are attached to the vehicle by means of a magnet. They

affect the operation of the compass.

2. If the compass deviates from the correct indication soon after repeated adjustment, have the compass

checked at an authorized dealer.

3. The compass may not indicate the correct compass point in tunnels or while driving up or down a steep

hill. (The compass returns to the correct compass point when the vehicle moves to an area where the
geomagnetism is stabilized.)

3.

Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not
spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.

“C” is Displayed In the Compass Window

The compass needs to be calibrated. Drive the vehicle in 3 circles at 8km/h (5MPH) or less until the display
reads a direction. You can also calibrate the compass by driving your vehicle on your everyday routine. The
compass will be calibrated once it has tracked 3 complete circles.

Inaccurate Compass Direction

1.

With the display turned on, push the “COMP” switch for 3 sec-
onds, until the zone selection comes up (a number will be dis-
played in the mirror compass window).

2.

Toggle until correct zone is found and release switch.

3.

The display will show all segments, and return to the normal
compass mode within 10 seconds of no switch activity.

4.

If the vehicle changes zone, repeat steps 1 through 3. See map.
