4.CHECK VEHICLE SPEED INPUT SIGNAL
1. Connect 4WD/ABS control unit (without EPS)or 4WD control
unit (with EPS) connector.
2. Lift up drive wheels.
3. Start engine.
4. Check voltage signal between combination meter harness con-
nector M46 terminal 52 (R/B) and ground.
OK or NG?
OK >> Replace combination meter.
NG >> Check ABS system.
Inspection/Fuel Level Sensor UnitEKS002ZI
FUEL LEVEL SENSOR UNIT
The following symptoms do not indicate a malfunction.
lDepending on vehicle posture or driving circumstance, the fuel level in the tank varies, and the pointer
may fluctuate.
lIf the vehicle is fueled with the ignition switch ON, the pointer will move slowly.
LOW-FUEL WARNING LAMP
Depending on vehicle posture or driving circumstance, the fuel level in the tank varies, and the warning lamp
ON timing may be changed.
1.DIAGNOSIS MODE INSPECTION
Preform the combination meter diagnosis mode. Refer toDI-10, "
Meter/Gauge Operation and Odo/Trip Meter
Segment Check in Diagnosis Mode".
OK or NG
OK >> GO TO 2.
NG >> Replace combination meter.
2.HARNESS CONNECTOR INSPECTION
1. Turn the ignition switch OFF.
2. Check combination meter, fuel level sensor unit and terminals (meter-side, module-side, and harness-
side) for poor connection and bend.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace terminals or connectors.52 (R/B) – ground

Meter/Gauge Operation and Odo/Trip Meter Segment Check in Diagnosis Mode
EKS0030M
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 DiagnosesEKS0030N
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 ?
YES >> GO TO 2.
NO >> Power supply and ground circuit check. Refer toDI-30, "
Power Supply and Ground Circuit Check"
.
2.CHECK DIAGNOSIS MODE OPERATION
Preform diagnosis mode. Refer toDI-28, "
Meter/Gauge Operation and Odo/Trip Meter Segment Check in
Diagnosis Mode".
Can diagnosis mode be activated ?
YES >> GO TO 3.
NO >> Power supply and ground circuit check. Refer toDI-30, "
Power Supply and Ground Circuit Check"
.
