Meter/Gauge Operation and Odo/Trip Meter Segment Check in Diagnosis Mode
EKS002ZC
DIAGNOSIS FUNCTION
●Odo/trip meter segment can be checked in diagnosis mode.
●Meters/gauges can be checked in diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch to ON and change odo/trip meter to “TRIP A” or “TRIP B”.
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter switch.
4. Confirm that trip meter indicates “000.0”.
5. Push odo/trip meter switch more than three times within 5 seconds.
6. All odo/trip meter segments should be turned on.
NOTE:
If some segments are not turned on, unified meter control unit
with odo/trip meter should be replaced.
At this point, the unified control meter is turned to diagnosis
mode.
7. Push odo/trip meter switch. Indication of each meter/gauge
should be as shown left during pushing odo/trip meter switch if it
is no malfunctioning.
NOTE:
It takes about a few seconds for indication of fuel gauge and
water temperature gauge to become stable.
