CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
NOTE:

When any initialization is performed, all ID previously registered will be erased and all NATS ignition keys
must be registered again.

The engine cannot be started with an unregistered key. In this case, the system will show “DIFFERENCE
OF KEY” or “LOCK MODE” as a self-diagnostic result on the CONSULT-II screen.

CAUTION:

Do not perform active test while driving vehicle.

Make sure to completely bleed air from brake system.

The active test cannot be performed with the ABS warning lamp, VDC indicator lamp, SLIP indica-
tor lamp and brake warning lamp are on.

ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on
during active test.

Erase memory of ICC system after implementing active test. Refer to ACS-34, "Self-Diagnostic
Function" .
OPERATION PROCEDURE
1. Perform “CONSULT-II Starting Procedure”. Refer to GI-38, "CONSULT-II Start Procedure" .
2. Touch “SELECT TEST ITEM” is displayed.
3. Touch necessary test item.
4. While “MAIN SIGNALS” indication is inverted, touch “START”.
5. “ACTIVE TEST” screen will be displayed so perform the following test.
NOTE:

When active test is performed while depressing the pedal, the pedal depression amount will change.
This is normal. (Only solenoid valve and ABS motor)

“TEST IS STOPPED” is displayed 10 seconds after operation start.

After “TEST IS STOPPED” is displayed, to perform test again, touch “BACK” and repeat step 3.

COMBINATION METERSPFP:24814
System DescriptionNKS003TV
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter.
NOTE:
The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Dot matrix LCD is adopted to display “push engine starter”, “A/T position” and “ICC system* ”.

Odo/trip meter and dot matrix LCD segments can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
*: With ICC system
UNIFIED METER AND A/C AMP.
Refer to DI-28, "COMBINATION METER CONTROL FUNCTION" in “UNIFIED METER AND A/C AMP”.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No. 21, located in the fuse block (J/B)]

to combination meter terminal 23,

through 10A fuse [No. 19, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 54.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)],

to combination meter terminal 2, and

to unified meter and A/C amp. terminal 41.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 12,

through 10A fuse [No. 12, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 53.
Ground is supplied

to combination meter terminals 9, 10 and 11

to unified meter and A/C amp. terminals 55 and 71

through grounds M16 and M70.

METER ILLUMINATION CONTROL

Meter illumination* is controlled by the unified meter control unit.

Ring illumination under normal operation and engine start excitement function can be turned ON/OFF with
pressing meter illumination control switch for more than 1 second.
*: Illumination for ring, meter face, pointer, dot matrix LCD and odo/trip meter
Daytime Mode
Meter illumination is adjusted to 5 steps by meter illumination control
switch (1) in daytime mode.
Nighttime Mode

Combination meter is transferred to nighttime mode with position light request signal from BCM with CAN
communication.

Meter illumination is adjusted to 16 steps by illumination control
switch (1) in nighttime. Refer to LT- 2 9 3 , "
ILLUMINATION" .
Driver Welcome Function
Ring illumination gradually turns ON when a driver gets in the vehicle with intelligent key and closes the driver
side door.
NOTE:
Ring illumination gradually turns OFF when not turning the ignition switch ON at a certain period of time.
Engine Start Excitement Function
Combination meter detects the engine start when input engine speed signal at first. Pointers of speed meter
and tachometer sweep and ring illumination gradually turns ON when combination meter detects the engine
start. Then, combination meter starts the normal control.
NOTE:

Water temperature gauge and fuel gauge do not function.

Engine start excitement function can be turned ON/OFF with pressing meter illumination control switch for
more than 1 second.

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.
