5. CHECK VDCCM
Step
1 CHECK VEHICLE SPEED 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 be dragged in by the rotat-
ing wheel.
3) Measure the voltage between combination
meter connector and chassis ground.
Connector & terminal
(i10) No. 27 (+) — Chassis ground (–):
2 CHECK HARNESS BETWEEN VDCCM AND
COMBINATION METER.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from VDCCM and
combination meter.
3) Measure the resistance between VDCCM
harness connector and combination meter har-
ness connector.

6. CHECK ENGINE CONTROL MODULE (ECM)
Step
1 CHECK ECM SIGNAL.
1) Start the engine.
2) Measure the voltage between ECM connec-
tor and chassis ground.
Connector & terminal
(B136) No. 11 (+) — Chassis ground (– ):
2 CHECK HARNESS BETWEEN COMBINA-
TION METER AND ECM.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM and
combination meter.
3) Measure the resistance between ECM har-
ness connector and combination meter harness
connector.
