Self-Diagnosis Mode of Combination Meter

NKS001S7

SELF-DIAGNOSIS FUNCTION

●

Odo/trip meter and CVT indicator segments operation can be checked in self-diagnosis mode.

●

Meters/gauges can be checked in self-diagnosis mode.

OPERATION PROCEDURE

Turn ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.

NOTE:
If the self-diagnosis function is activated with the “trip A” displayed, only “trip A” display is reset.

Turn ignition switch OFF.

While pushing the odo/trip meter switch, turn ignition switch ON
again.

Make sure the trip meter displays “0000.0”.

Push the odo/trip meter switch at least 3 times (within 7 seconds
after the ignition switch is turned ON)

All the segments on the odo/trip meter and CVT indicator illuminate, and simultaneously the low-fuel
warning lamp indicator illuminates. At this time, the unified meter control unit is turned to self-diagnosis
mode.

NOTE:

●

Check odo/trip meter switch and combination meter power supply and ground circuit when self-diagno-
sis mode of combination meter dose not start. Replace combination meter if the results of the check are
normal.

●

If any of the segments are not displayed, replace combination meter.

Each meter/gauge activates during pressing odo/trip meter
switch. (Then low-fuel warning lamp turns OFF.)

NOTE:

●

If any of the meters/gauges are not activated, replace the
combination meter.

●

The figure is reference.

System Description

NKS001SN

●

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.

●

The unified meter and A/C amp. corresponds to a CONSULT-II function (self-diagnosis results, CAN diag-
nosis support monitor, data monitor).

COMBINATION METER CONTROL FUNCTION

●

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

●

Unified meter and A/C amp. transmits a signals with communication line (TX, RX) between unified meter
and A/C amp. and combination meter.
