Solar Sensor (For Automatic Air Conditioning System) Inspection
INSPECT SOLAR SENSOR
Solar Sensor (For Automatic Air Conditioning System) -- Inspection |
Measure the resistance according to the value(s) in the table below.
- NOTICE:
- Connect the ohmmeter's negative (-) lead to terminal 1 and positive (+) lead to terminal 2.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
1 - 2
| Sensor is subjected to electric light
| Below 10 kΩ
|
Sensor is covered with a cloth
| 10 kΩ or higher
|
If the result is not as specified, replace the solar sensor.
- NOTICE:
- The connection procedure for a digital tester, such as a TOYOTA electrical tester, is shown above. When using an analog tester, connect the negative (-) lead to terminal 2 and the positive (+) lead to terminal 1.
- HINT:
- As the inspection light is moved away from the sensor, the resistance increases.
- Use an incandescent light for inspection. Bring it within 30 cm (11.8 in.) of the A/C solar sensor.
