4. CHECK TRANSMISSION CONTROL MODULE (TCM)
3 CHECK HARNESS BETWEEN VEHICLE
SPEED SENSOR AND ENGINE GROUND.
1) Turn the ignition switch to OFF.
2) Measure the resistance between vehicle
speed sensor connector and engine ground.
Connector & terminal
(B17) No. 2 — Engine ground:
Is the resistance less than 10
Ω?
Go to step 4. Repair the wiring
harness.
4 CHECK HARNESS BETWEEN VEHICLE
SPEED SENSOR AND COMBINATION
METER.
1) Disconnect the connector from combination
meter.
2) Measure the resistance between vehicle
speed sensor harness connector and combi-
nation meter harness connector.
Connector & terminal
(B17) No. 1 — (i10) No. 12:
Is the resistance less than 10
Ω?
Replace the vehi-
cle speed sensor.
Repair the wiring
harness.
Step Check Yes No
1 CHECK TCM SIGNAL.
1) Lift-up the vehicle and support it with rigid
racks.
2) Drive the vehicle faster than 10 km/h (6
MPH).
Warning:
Be careful not to get caught in the running
wheels.
3) Measure the voltage between TCM con-
nector and chassis ground.
Connector & terminal
(B56) No. 17 (+) — Chassis ground (
− ):
Is the voltage 1 V ← → 5 V? Go to step 2. Check TCM. <Ref.
to 4AT(H4SO)-2,
Basic Diagnostic
Procedure.>
2 CHECK HARNESS BETWEEN TCM AND
COMBINATION METER.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from TCM and
combination meter.
3) Measure the resistance between TCM har-
ness connector and combination meter har-
ness connector.
Connector & terminal
(B56) No. 17 — (i10) No. 12:
Is the resistance less than 10
Ω?
Check the speedo
meter. <Ref. to IDI-
13, INSPECTION,
Speedometer.>
Repair the wiring
harness.
Step Check Yes No
