B: INSPECTION S907607A10
CAUTION:
When measuring voltage and resistance of the ECM, TCM, or each 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).

2. CHECK POWER SUPPLY AND
GROUND CIRCUIT S907607A1001
No. Step Check Yes No
1 CHECK POWER SUPPLY FOR COMBINA-
TION METER.
1) Remove combination meter. <Ref. to IDI-15
REMOVAL, Combination Meter Assembly.>
2) Disconnect combination meter harness
connector.
3) Turn ignition switch to ON.
4) Measure voltage between combination
meter connector (i10) and chassis ground.
Connector & terminal
(i10) No. 1 (+) —Chassis ground (−):
Is the voltage more than 10
V? Go to step 2. Check harness for open or short
between fuse and
combination
meter.
2 CHECK POWER SUPPLY FOR COMBINA-
TION METER.
Measure voltage between combination meter
connector (i10) and chassis ground.
Connector & terminal
(i10) No. 2 (+) —Chassis ground (−):
Is the voltage more than 10
V? Go to step 3. Check harness for open or short
between ignition
relay and combi-
nation meter.
3 CHECK GROUND CIRCUIT OF COMBINA-
TION METER.
1) Turn ignition switch to OFF.
2) Measure resistance of harness between
combination meter connector (i10) and chas-
sis ground.
Connector & terminal
(i10) No. 3 (+) —Chassis ground (−):
Is the resistance less than
10 Ω?Replace combina- tion meter printed
circuit.
Repair wiring har-
ness.

3. CHECK VEHICLE SPEED SENSOR
S907607A1002
No. Step Check Yes No
1 CHECK VEHICLE SPEED SENSOR.
1) Set the vehicle on a free roller, or lift-up the
vehicle and support it with safety stands.
2) Remove the combination meter with har-
ness connector.
WARNING:
Be careful not to get caught in the running
wheels.
3) Drive the vehicle at a speed greater than
20 km/h (12 MPH).
4) Measure voltage between combination
meter connector (i10) and chassis ground.
Connector & terminal
(i10) No. 7 (+) —Chassis ground (−):
Is the voltage less than 1 V
←→ more than 4? Check speedom- eter. <Ref. to
IDI-17 REMOVAL,
Speedometer.>
Go to step 2.
2 CHECK VEHICLE SPEED SENSOR POWER
SUPPLY.
1) Turn ignition switch to OFF.
2) Disconnect vehicle speed sensor harness
connector.
3) Turn ignition switch to ON.
4) Measure voltage between vehicle speed
sensor connector (B17) and engine ground.
Connector & terminal
(B17) No. 3 (+) —Engine ground (−):
Is the voltage more than 10
V? Go to step 3. Check harness for open or short
between ignition
relay and vehicle
speed sensor.
3 CHECK HARNESS BETWEEN VEHICLE
SPEED SENSOR AND ENGINE GROUND.
1) Turn ignition switch to OFF.
2) Measure resistance between vehicle speed
sensor connector (B17) and engine ground.
Connector & terminal
(B17) No. 2 (+) —Engine ground (−):
Is the resistance less than
10 Ω?Go to step 4. Repair wiring har- ness.
4 CHECK HARNESS BETWEEN VEHICLE
SPEED SENSOR AND COMBINATION
METER.
1) Disconnect connector from combination
meter.
2) Measure resistance between vehicle speed
sensor harness connector and combination
meter harness connector.
Connector & terminal
(B17) No. 1 —(i10) No. 7:
Is the resistance less than
10 Ω?Replace vehicle speed sensor. Repair wiring har- ness.
