Toyota RAV4 (XA40) 2013-2018 Service Manual: Solar sensor (for automatic air conditioning system)
Components
Removal
- Disconnect cable from negative battery terminal
Caution:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
- Remove solar sensor
- Using a screwdriver, pull out the solar sensor, then disconnect the connector.
Hint:
Tape the screwdriver tip before use.
Inspection
- Inspect solar sensor
- Using an ohmmeter, connect the positive lead to terminal 2 and the negative lead to terminal 1, then measure the resistance between the terminals.
Standard resistance 
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 1 and the negative (-) lead to terminal 2 of the a/c solar sensor.
Hint:
- As the inspection light is moved away from the sensor, the voltage increases.
- 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 solar sensor.
Installation
- Install solar sensor
- Connect the connector, and then push in the solar sensor.
- Connect cable to negative battery terminal
- Check srs warning light
- Check the srs warning light (see page rs-37).
