3. CHECK VEHICLE SPEED SENSOR
Step Check Yes No
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 (
−
):
Is the voltage more than 10 V? Go to step 2. Check the harness
for open or short
between ignition
switch and combi-
nation meter.
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 (
−
):
Is the voltage more than 10 V? Go to step 3. Check the harness
for open or short
between 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
(i10) No. 10 — Chassis ground:
Is the resistance less than 10
Ω?
Replace the com-
bination meter
printed circuit.
Repair the wiring
harness.
Step Check Yes No
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 (
−
):
Is the voltage 1 V ← → 5 V? Check the speed-
ometer. <Ref. to
IDI-13, INSPEC-
TION, Speedome-
ter.>
Go to step 2.
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 (
−
):
Is the voltage more than 10 V? Go to step 3. Check the harness
for open or short
between ignition
switch and vehicle
speed sensor.
