4. SENSOR CHECK TABLE
NOTE:
When the sunload sensor check is performed indoors or in the shade, it could be diagnosed as having an
open circuit. Always check the sunload sensor with the sun shining on it.
*1: “AUTO” display does not blink when past malfunction occurred. Past malfunction means that abnormal signals were contin-
uously input for a certain time in the past.
*2: Present malfunction only is displayed for sunload sensor open circuit.

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 more
than 2 mm (0.08 in).

1) Remove the combination meter. IDI-11, REMOVAL, Combination Meter.>
2) Disconnect the combination meter harness
connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between combination
meter connector and chassis ground.
Connector & terminal
(i10) No. 3, 4 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 2.Check the harness
for open or shor t
between the igni-
tion switch and
combination
meter.
