The Fuel Gauge Does Not Move to Full-position.EKS0030V
1.QUESTION 1
Does it take a long time for the pointer to move to Full-position?
Ye s o r N o
Ye s > > G O T O 2 .
No >> GO TO 3.
2.QUESTION 2
Was the vehicle fueled with the ignition switch ON?
Ye s o r N o
Yes >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise it will take a long time to move
to Full-position because of the characteristic of the fuel gauge.
No >> GO TO 3.
3.QUESTION 3
Is the floor or the vehicle inclined?
Ye s o r N o
Yes >> It may not be filled fully.
No >> GO TO 4.
4.QUESTION 4
During driving, does the fuel gauge pointer move gradually toward E-position?
Ye s o r N o
Yes >> Check the components. Refer to DI-41, "Electrical Components Inspection" .
No >> The float arm may interfere or bind with any of the components in the fuel tank.
The Fuel Gauge Does Not Work.EKS0030W
1.HARNESS CONNECTOR INSPECTION
1. Turn the ignition switch OFF.
2. Check combination meter, fuel level sensor unit, sub fuel level sensor unit and terminals (meter-side,
module-side, and harness-side) for poor connection and bend.
OK or NG
OK >> GO TO 2.
NG >> Repair connector.
2.CHECK INSTALLATION CONDITION
Check fuel level sensor unit or sub fuel level sensor unit installation (refer toFL-4, "
FUEL LEVEL SENSOR
UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY" for QR engine models or FL-17, "FUEL LEVEL SEN-
SOR UNIT" for YD engine models, and check whether the float arm interferes or binds with any components
inside the arm.
OK or NG
OK >> Fuel level sensor unit is OK.
NG >> Check fuel level sensor unit or sub fuel level sensor unit. Refer to DI-41, "
Electrical Components
Inspection" .

WARNING LAMPS
Electrical Components Inspection
EKS002HK
FUEL WARNING LAMP OPERATION CHECK
1. Turn ignition switch “OFF”.
2. Disconnect sub fuel level sensor unit harness connector B125
(LHD models) or B21 (RHD models).
3. Connect a resistor (80Ω) between sub fuel level sensor unit har-
ness connector terminal 1(G) and ground.
4. Turn ignition switch “ON”.
The fuel warning lamp should come on.
OIL PRESSURE SWITCH CHECK
Check the continuity between the terminals of oil pressure switch
and body ground.
DIODE CHECK
●Check continuity using an ohmmeter.
●Diode is functioning properly if test results are as shown in the
figure at left.
●Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer toDI-44,
"Wiring Diagram — WARN —/ LHD Models" orDI-50, "Wiring
Diagram — WARN — / RHD Models" .
NOTE:
Specification may vary depending on the type of tester. Before
performing this inspection, be sure to refer to the instruction
manual for the tester to be used.
