3. CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect combination meter connector.
3. Check continuity between combination meter harness connector
M44 terminals 21 (B) and ground.
OK or NG
OK >> INSPECTION END
NG >> Check ground harness.

6. CHECK INSTALLATION CONDITION
Check fuel level sensor unit installation, and check whether the float arm interferes or binds with any of the
internal components in the fuel tank.
OK or NG
OK >> Replace combination meter.
NG >> Install fuel level sensor unit properly.
Engine Speed Signal Inspection EKS00EHD
1. CHECK ECM SELF-DIAGNOSIS
Perform ECM self-diagnosis. Refer to EC-103, "
CONSULT-II Function (ENGINE)" [QR (WITH EURO-OBD)],
EC-604, "
CONSULT-II Function (ENGINE)" [QR (WITHOUT EURO -OBD)] or EC-1034, "CONSULT-II Func-
tion (ENGINE)" [YD].
OK or NG
OK >> Replace combination meter.
NG >> Perform “Diagnostic Procedure” in displayed DTC.

1. CHECK ECM SELF-DIAGNOSIS
Perform ECM self-diagnosis. Refer to EC-103, "
CONSULT-II Function (ENGINE)" [QR (WITH EURO-OBD)],
EC-604, "
CONSULT-II Function (ENGINE)" [QR (WITHOUT EURO - OBD)] or EC-1034, "CONSULT-II Func-
tion (ENGINE)" [YD].
OK or NG
OK >> Replace combination meter.
NG >> Perform “Diagnostic Procedure” in displayed DTC.
Vehicle Speed Signal Inspection [With ESP]EKS00EHF
1. CHECK ESP/TCS/ABS CONTROL UNIT SELF-DIAGNOSIS
Perform ESP/TCS/ABS control unit self-diagnosis. Refer to BRC-79, "
CONSULT-II Functions" .
OK or NG
OK >> Replace combination meter.
NG >> Check applicable parts.
Vehicle Speed Signal Inspection [Without ESP]EKS00EJB
1. CHECK ABS ACTUATOR CONTROL UNIT SELF-DIAGNOSIS
Perform ABS actuator and electric unit self-diagnosis. Refer to BRC-26, "
CONSULT- II Functions" .
OK or NG
OK >> Replace combination meter.
NG >> Check applicable parts.
The Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or VariesEKS00EHG
1. CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or at the instant of stopping.
Does the indication value vary only during driving or at the instant of stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
