Meter/Gauge Operation and Odo/Trip Meter Segment Check in Diagnosis Mode
EKS002ZC
DIAGNOSIS FUNCTION
lOdo/trip meter segment can be checked in diagnosis mode.
lMeters/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.
Trouble DiagnosesEKS002ZD
PRELIMINARY CHECK
1.CHECK WARNING LAMPS
1. Turn ignition switch ON.
2. Warning lamps should illuminate (seat belt warning or door warning etc.).
Do warning lamps illuminate?
