CAUTION:
When measuring the voltage and resistance of each control module or 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 of more
than 2 mm (0.08 in) in diameter.

meter connector and chassis ground.

Connector & terminal

(i10) No. 19 (+) — Chassis ground (

−

):

Is the voltage less than 1 V
←→ 5 V or more?

Replace the meter
case assembly.

Go to step 2.

2

CHECK HARNESS BETWEEN ABSCM OR
VDCCM AND COMBINATION METER.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ABSCM or
VDCCM and combination meter.
3) Measure the resistance between ABSCM
or VDCCM harness connector and combina-
tion meter harness connector.
