INSTRUMENTATION/DRIVER INFO

5. CHECK ENGINE CONTROL MODULE (ECM)

1

2

Step

CHECK ECM SIGNAL.

1) Start the engine.

2) Measure the voltage between ECM connector and engine ground.

Connector & terminal

Non-turbo model

(B134) No. 10 (+) — Engine ground (

−

):

Turbo model

(B134) No. 23 (+) — Engine ground (

−

):

Check Yes

Is the voltage 0 V

← → 14 V? Go to step 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 harness connector and combination meter harness 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?

No

Check ECM. <Ref. to EN(H4SO)-2,

Basic Diagnostics

Procedure.> <Ref. to EN(H4DOTC)-2,

Basic Diagnostics

Procedure.>

Check the tachom-

eter. <Ref. to IDI-

14, INSPECTION,

Tachometer.>

Repair the wiring harness.

6. CHECK FUEL LEVEL SENSOR

3

Step

Is the resistance 0.5 to 2.5

Ω

(FULL) and 50 to 52

Ω

(EMPTY)?

Check

CHECK FUEL LEVEL SENSOR.

1) Remove the fuel level sensor. <Ref. to

FU(H4SO)-57, REMOVAL, Fuel Level Sensor.>

2) Measure the resistance between fuel level sensor terminals when setting the float to

FULL and EMPTY position.

Terminals

No. 3 — No. 5:

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)?

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 terminal.

Connector & terminal

(R59) No. 1 — (i11) No. 1:

Is the resistance less than 10

Ω?

Yes

Go to step 2.

Go to step 3.

Go to step 4.

No

Replace the fuel level sensor.

Replace the fuel sub level sensor.

Repair the wiring harness.
