Basic Diagnostics
Procedure.> <Ref.
to EN(H4DOTC)-2,
Basic Diagnostics
Procedure.>
2
CHECK HARNESS BETWEEN COMBINA-
TION METER AND ECM.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM and
combination meter.
3) Measure the resistance between ECM har-
ness connector and combination meter har-
ness connector.
Connector & terminal
Non-turbo model
(B134) No. 10 — (i10) No. 11:
Turbo model
(B134) No. 23 — (i10) No. 11:
Is the resistance less than 10
Ω
?
Check the tachom-
eter. <Ref. to IDI-
14, INSPECTION,
Tachometer.>
Repair the wiring
harness.
Step
Check
Yes
No
1
CHECK FUEL LEVEL SENSOR.
1) Remove the fuel level sensor. <Ref. to
FU(H4SO)-57, REMOVAL, Fuel Level Sen-
sor.>
2) Measure the resistance between fuel level
sensor terminals when setting the float to
FULL and EMPTY position.
Terminals
No. 3 — No. 5:
Is the resistance 0.5 to 2.5
Ω
(FULL) and 50 to 52
Ω
(EMPTY)?
Replace the fuel
level sensor.
2
CHECK FUEL SUB LEVEL SENSOR.
1) Remove the fuel sub level sensor. <Ref. to
FU(H4SO)-58, REMOVAL, Fuel Sub Level
Sensor.>
2) Measure the resistance between fuel sub
level sensor terminals when setting the float to
FULL and EMPTY position.
Terminals
No. 1 — No. 2:
Is the resistance 0.5 to 2.5
Ω
(FULL) and 42 to 44
Ω
(EMPTY)?
Replace the fuel
sub level sensor.
3
CHECK HARNESS BETWEEN FUEL SUB
LEVEL SENSOR AND COMBINATION
METER.
1) Disconnect the connector from combination
meter.
2) Measure the resistance between fuel sub
level sensor harness connector terminal and
combination meter harness connector termi-
nal.
Connector & terminal
(R59) No. 1 — (i11) No. 1:
Is the resistance less than 10
Ω
?
Repair the wiring
harness.
