Meter/Gauges Operation and Odo/Trip MeterEKS00EH7
SELF-DIAGNOSIS FUNCTION

Odo/trip meter segment operation can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with the trip meter A displayed, the mileage on the trip meter A will
indicate 0.0 miles, but the actual trip mileage will be retained. (Trip B operates the same way.)
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0.0”.
5. Push the odo/trip meter switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)
6. All the segments on the odo/trip meter illuminate, and simultaneously the low-fuel warning lamp indicator
illuminates. At this time, the unified meter control unit is turned to diagnosis mode.
NOTE:
If any of the segments is not displayed, replace the combination
meter.

Fuel Level Sensor Inspection [Gasoline Engine Models]EKS00EHC
The following symptoms do not indicate a malfunction.
FUEL GAUGE

Depending on vehicle posture or driving circumstance, the fuel level changes and the pointer may fluctu-
ate.

If 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 changes and the warning lamp ON timing
may change.
1. CHECK HARNESS CONNECTOR
Check combination meter and fuel level sensor unit terminals (meter side, unit side harness side) for loose-
ness or bent terminals.
OK or NG
OK >> GO TO 2.
NG >> Repair terminal or connector.
2. CHECK COMBINATION METER CIRCUIT
1. Disconnect combination meter connector and sub fuel level sen-
sor unit connector.
2. Check continuity between combination meter harness connector
M44 terminal 8 (G) and sub fuel level sensor unit harness con-
nector B125
*1 or B21*2 terminal 1 (G).
3. Check continuity between combination meter harness connector
M44 terminal 8 (G) and ground.
NOTE:
*1: LHD models, *2: RHD models
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK FUEL LEVEL SENSOR CIRCUIT
1. Disconnect fuel level sensor unit connector.
2. Check continuity between sub fuel level sensor unit harness
connector B125
*1 or B21*2 terminal 3 (Y) and fuel level sensor
unit harness connector B31
*1 or B123*2 terminal 4 (Y).
3. Check continuity between sub fuel level sensor unit harness
