FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
from unified meter and A/C amp. terminal 58
through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
through the fuel level sensor unit (sub) terminals 2 and 1
to unified meter and A/C amp. terminal 42.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
ODO/TRIP METER
ABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmits vehicle speed signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. converses vehicle speed signal to 8 pulse signal, and transmits to combina-
tion meter.
Combination meter processes the 8 pulse signal and the memory signals from the meter memory circuit.
Then the mileage is displayed.
How to Change The Display For Odo/trip Meter
Operating the odo/trip meter switch allows switching the mode in the following order.
The odo/trip meter display switching and trip display resetting
can be identified by the time from pressing the odo/trip meter
switch (1) to releasing it.
When resetting with “trip A” displayed, only “trip A” display is
reset. (The same way for “trip B”.)

Self-Diagnosis Mode of Combination MeterNKS003U2
SELF-DIAGNOSIS FUNCTION
Odo/trip meter segment and dot matrix LCD segment operation can be checked in self-diagnosis mode.
Meters/gauges can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” is reset to “0000.0”.
(The same way for “trip B”.)
2. Turn ignition switch OFF.
3. While pressing the odo/trip meter switch (1), turn ignition switch
ON again.
4. Make sure that the trip meter displays “0000.0”.
5. Press the odo/trip meter switch (1) at least 3 times. (Within 7
seconds after the ignition switch is turned ON.)
6. The unified meter control unit is turned to self-diagnosis mode.
Dot in all segments of dot matrix LCD (1) flashes alternately.
All the segments on the odo/trip meter (2) illuminates.
Water temperature gauge and fuel gauge return to zero, and at the same time, low-fuel warning indica-
tor turns ON.
NOTE:
Check combination meter power supply and ground circuit when self-diagnosis mode of combination
meter does not start. Replace combination meter if normal.
If any of the segments is not displayed, replace combination meter.
7. Each meter activates during pressing odo/trip meter switch.
(Then low-fuel warning lamp turns OFF.)
NOTE:
If any of the meter and gages is not activated, replace combina-
tion meter.

Multiport Fuel Injection (MFI) SystemNBS004S3
INPUT/OUTPUT SIGNAL CHART
*1: This sensor is not used to control the engine system under normal conditions.
*2: This signal is sent to the ECM through CAN communication line.
*3: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from the crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the mass air flow sensor.
VARIOUS FUEL INJECTION INCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operat-
ing conditions as listed below.
During warm-up
When starting the engine
During acceleration
Hot-engine operation
When selector lever is changed from N to D

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Revision: 2006 January2006 M35/M45
OBD System Operation ChartNBS004SP
RELATIONSHIP BETWEEN MIL, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are
stored in the ECM memory.
When the same malfunction is detected in two consecutive trips, the DTC and the freeze frame data are
stored in the ECM memory, and the MIL will come on. For details, refer to EC-54, "
Two Trip Detection
Logic" .
The MIL will go off after the vehicle is driven 3 times (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction
occurs while counting, the counter will reset.
The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A)
without the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and
Fuel Injection System, the DTC and freeze frame data will be stored until the vehicle is driven 80 times
(driving pattern C) without the same malfunction recurring. The “TIME” in “SELF-DIAGNOSTIC
RESULTS” mode of CONSULT-II will count the number of times the vehicle is driven.
The 1st trip DTC is not displayed when the self-diagnosis results in OK for the 2nd trip.
SUMMARY CHART
For details about patterns B and C under “Fuel Injection System” and “Misfire”, see EC-74, "EXPLANATION FOR DRIVING PATTERNS
FOR “MISFIRE
For details about patterns A and B under Other, see EC-76, "
EXPLANATION FOR DRIVING PATTERNS EXCEPT FOR “MISFIRE
