Solar Sensor: Testing and Inspection








AIR CONDITIONING: SOLAR SENSOR: INSPECTION

INSPECTION

1. INSPECT SOLAR SENSOR






(a) Remove the A/C solar sensor with the connector still connected.
(b) Apply battery voltage between terminals 6 (CLTB) and 3 (CLTE) of the A/C solar sensor.
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:





NOTICE:
- 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 2 and negative (-) lead to terminal 1 of the solar sensor.
- While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
HINT:
- Use an incandescent light for inspection. Bring it within about 30 cm (11.8 in.) of the solar sensor.
- As the inspection light is moved away from the sensor, the voltage increases.
