Step

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?

Check

Step

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).

Check Yes

Is the voltage 1 V

← → 5 V?

Go to step 2.

Warning:

Be careful not to get caught in the running wheels.

3) Measure the voltage between TCM connector and chassis ground.

(B56) No. 17 (+) — Chassis ground (

−

):

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 harness connector and combination meter harness connector.

Connector & terminal

(B56) No. 17 — (i10) No. 12:

Is the resistance less than 10

Ω?

No

Check TCM. <Ref. to 4AT(H4SO)-2,
