1. INSPECT COOLER (SOLAR SENSOR) THERMISTOR
(a) Using an ohmmeter, connect the positive lead to terminal 2 and the negative lead to terminal 1, then measure the resistance according to the
value(s) in the table below.
Standard resistance:
NOTE:
The connection procedure for using a digital tester such as a TOYOTA electrical tester is shown above. When using an analog tester, connect
the positive (+) lead to terminal 1 and the negative (-) lead to terminal 2 of the A/C solar sensor.
HINT: Use an incandescent lamp for inspection. Bring it within 30 cm (11.8 in.) of the A/C solar sensor.
If the result is not as specified, replace the thermistor.
