< SYSTEM DESCRIPTION >
SYSTEM
 The combination meter judges showing/hiding of “other warning”, according to the signals below:
Meter Illumination Level Indication
When receiving the following signals, the combination meter causes an interrupt on the information display to
indicate an illumination level.
WARNING CHECK INDICATION
 The combination meter can cause an interrupt on the information display to indicate a warning, based onsignals received from each unit and switch.
 The indicated warning can be checked with “WARNING” during the satisfaction of an interrupt indication
condition for each warning.
SETTING
Warning indication timing and time can be set.
Alert
Setting values for travel time, and low ambient te mperature can be adjusted to meet the user's needs.
Maintenance
Setting values for engine oil, oil filter, tire, and other maintenance items can be adjusted to meet the user's
needs.
Options
Setting values for unit and effect items can be adjusted to meet the user's needs.
Operating condition
Ignition switch ON
Mileage More than value set in “SETTING”

On Board Diagnosis FunctionINFOID:0000000006221719
ON BOARD DIAGNOSIS ITEM
The combination meter allows the following diagnosis items with the on-board diagnosis function.
METHOD OF STARTING
1. Turn ignition switch OFF.
2. While pressing the trip reset switch (1), turn ignition switch ON.
3. 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”.)
4. Make sure that the trip meter displays “0000.0”.
5. Press the trip reset switch at least 3 times. (Wit hin 7 seconds after the ignition switch is turned ON.)
6. The combination meter is turned to self-diagnosis mode.  Speedometer, tachometer, engine coolant temper ature gauge, fuel gauge, engine oil pressure gauge,
and voltmeter return to zero, simultaneously.
 The dot matrix dots on the information display (1) blink alter-
nately.
NOTE:
 Check combination meter power supply and ground circuit when the self-diagnosis mode of the combi- nation meter does not start. Replace combination meter if power supply and ground circuit are normal.
 If any of the dots are not displayed, replace combination meter.
