SOLAR SENSOR INSPECTION

PROCEDURE


  1. INSPECT SOLAR SENSOR (AUTOMATIC LIGHT CONTROL SENSOR) (w/ Automatic Light Control System)

      (to Solar Sensor)

      Disconnect the F73 solar sensor connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      F73-3 (CLTB) - F73-5 (CLTE) Ignition switch off Below 1 V
      F73-3 (CLTB) - F73-5 (CLTE) Ignition switch ON 11 to 14 V
    3. Reconnect the solar sensor connector.

    4. Turn the ignition switch to ON.

      Component with harness connected

      (Solar Sensor)

      Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      F73-1(TSD) - F73-5(CLTE) Without direct light exposure (Sensor covered) Below 0.8 V
      F73-1(TSD) - F73-5(CLTE) When exposed to sunlight or an inspection light 4.0 to 4.6 V

      Note

      Use an incandescent light for inspection. Bring it within about 30 cm (11.8 in.) of the solar sensor.

      If the result is not as specified, replace the solar sensor.

  2. INSPECT SOLAR SENSOR (COOLER THERMISTOR) (w/o Automatic Light Control System)


    1. A01UY78E02

      *a

      Component without harness connected

      (Solar Sensor)

      Connect the positive (+) lead from the ohmmeter to terminal 1 and the negative (-) lead to terminal 2 of the solar sensor.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 Without direct light exposure (Sensor covered) ∞ Ω
      1 - 2 When exposed to sunlight or an inspection light Except ∞ Ω

      Note

      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 2 and the negative (-) lead to terminal 1 of the solar sensor.

      Tech Tips


      • As the inspection light is moved away from the sensor, the voltage decreases.

      • Use an incandescent light for the inspection. Position it about 30 cm (11.8 in.) from the solar sensor.

      If the result is not as specified, replace the cooler thermistor.
