Toyota RAV4 Service Manual: Solar sensor circuit (driver side)

Toyota RAV4. Solar sensor circuit (driver side)


Description

The solar sensor, which is installed on the upper side of the instrument panel, detects sunlight and controls the air conditioning auto mode. The output voltage from the solar sensor varies in accordance with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases.

The air conditioning amplifier detects changes in the output voltage from the solar sensor.

  1. Inspect solar sensor

Toyota RAV4. Inspect solar sensor


  1. Remove the solar sensor.
  2. Measure the resistance of the sensor.
  3. Connect the ohmmeter's positive (+) lead to terminal 1 and the negative (-) lead to terminal 3 of the solar sensor.

Standard resistance


Notice:

The connection procedure for using a digital tester such as an electrical tester is shown above. When using an analog tester, connect the positive (+) lead to terminal 3 and the negative (-) lead to terminal 1 of the solar sensor.

Hint:



  1. Check wire harness (solar sensor - air conditioning amplifier)

Pressure sensor circuit
Description This dtc is output when the refrigerant pressure is either extremely low (0.19 Mpa [2.0 Kgf/cm2, 28 psi] or less) or extremely high (3.14 Mpa [32.0 Kgf/cm2, 455 psi] or more). The ...

Air mix damper control servo motor circuit (passenger side)
Description The air mix damper servo sends pulse signals to indicate the damper position to the air conditioning amplifier. The air conditioning amplifier activates the motor (normal or reve ...

Diagnosis system
Description The center airbag sensor controls the functions of the supplemental restraint system (srs) on the vehicle. Data of the srs can be read in the data link connector 3 (dlc3) of the vehicle. When the system seems to be malfunctioning, use the intelligent tester to check for a ma ...

Sensor (motor) failure
Description When the sliding roof drive gear (sliding roof ecu) detects the motor's malfunction, and the sliding roof operation is stopped, dtc b2341 is output. When the sliding roof drive gear (sliding roof ecu) detects the gear's malfunction, and the sliding roof operation is stopped, d ...

Fail-safe chart
Fail-safe function When communication fails in any of the main wires (communication lines) due to a short circuit or other causes, the fail-safe function, which is specified for each system, operates to prevent the system from malfunctioning. The table below shows the effects on e ...
