4. SYMPTOM CHART

CAUTION:
When measuring the voltage and resistance of each control module or sensor, use a tapered pin with
a diameter of less than 0.64 mm (0.025 in) in order to avoid poor contact. Do not insert the pin more
than 2 mm (0.08 in).

5. CHECK POWER SUPPLY AND GROUND CIRCUIT

Step

Check

Yes

No

1

CHECK POWER SUPPLY FOR COMBINA-
TION METER.
1) Remove the combination meter. <Ref. to 
IDI-22, REMOVAL, Combination Meter.>
2) Disconnect the combination meter harness 
connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between combination 
meter connector and chassis ground.

Connector & terminal

(i10) No. 3 (+) — Chassis ground (–):

Is the voltage 10 V or more?

Go to step 2.

Check the harness 
for open or short 
between the igni-
tion switch and 
combination meter.

2

CHECK POWER SUPPLY FOR COMBINA-
TION METER.
Measure the voltage between combination 
meter connector and chassis ground.

Connector & terminal

(i10) No. 1 (+) — Chassis ground (–):

Is the voltage 10 V or more?

Go to step 3.

Check the harness 
for open or short 
between the fuse 
and combination 
meter.

3

CHECK GROUND CIRCUIT OF COMBINA-
TION METER.
1) Turn the ignition switch to OFF.
2) Measure the resistance of harness between 
combination meter connector and chassis 
ground.

Connector & terminal

Normal meter model:
(i10) No. 11 — Chassis ground:
(i10) No. 12 — Chassis ground:
Multi information display model:
(i10) No. 11 — Chassis ground:
(i10) No. 12 — Chassis ground:

Is the resistance less than 10 

:? Replace the meter 

case assembly.

Repair the wiring 
harness.

1

CHECK VEHICLE SPEED SIGNAL.
1) Lift up the vehicle and support it with rigid 
racks.
2) Remove the combination meter with har-
ness connector.
3) Drive the vehicle faster than 10 km/h (6 MPH).

WARNING:
Be careful not to get caught in the running
wheels.
4) Measure the voltage between combination 
meter connector and chassis ground.

Connector & terminal

(i10) No. 19 (+) — Chassis ground (–):

Is the voltage less than 1 V 

mo

5 V or more?

Replace the meter 
case assembly.

Go to step 2.

2

CHECK HARNESS BETWEEN ABSCM OR 
VDCCM AND COMBINATION METER.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ABSCM or 
VDCCM and combination meter.
3) Measure the resistance between ABSCM or 
VDCCM harness connector and the combina-
tion meter harness connector.

Model with VDC

(B310) No. 33 — (i10) No. 19:

Is the resistance less than 10 

:? Model without 

VDC: Check the 
ABSCM. <Ref. to 
ABS(diag)-2, Basic 
Diagnostic Proce-
dure.> Model with

CHECK ECM SIGNAL.
1) Start the engine.
2) Measure the voltage between ECM connec-
tor and chassis ground.

Connector & terminal

(B136) No. 22 (+) — Chassis ground (–):

Is the voltage 0 

mo 14 V or 

more?

Go to step 2.

Inspect the ECM.

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 harness 
connector.

Connector & terminal

(B136) No. 22 — (i10) No. 20:

Is the resistance less than 10 

:? Replace the meter
