2. CHECK POWER SUPPLY AND GROUND CIRCUIT
Step
1 CHECK POWER SUPPLY FOR COMBINA-
TION METER.
1) Remove the combination meter. <Ref. to
IDI-10, REMOVAL, Combination Meter
Assembly.>
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. 9 (+) — Chassis ground (
2 CHECK POWER SUPPLY FOR COMBINA-
TION METER.
Measure the voltage between combination
meter connector and chassis ground.
Connector & terminal
(i10) No. 8 (+) — Chassis ground (
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
(i10) No. 10 — Chassis ground:
3. CHECK VEHICLE SPEED SENSOR
Step
1 CHECK VEHICLE SPEED SENSOR.
1) Lift-up the vehicle and support it with rigid
racks.
2) Remove the combination meter with har-
ness connector.
3) Drive the vehicle at a speed greater than 20
km/h (12 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. 12 (+) — Chassis ground (
2 CHECK VEHICLE SPEED SENSOR POWER
SUPPLY.
1) Turn the ignition switch to OFF.
2) Disconnect the vehicle speed sensor har-
ness connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between vehicle
speed sensor connector and engine ground.
Connector & terminal
(B17) No. 3 (+) — Engine ground (
