SOLAR SENSOR(for Automatic Air Conditioning System) INSPECTION

PROCEDURE

  1. INSPECT COOLER THERMISTOR (SOLAR SENSOR) (for LHD)

    1. U123672E02

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      I1-3 (TSP) - I1-1 (S5)

      Solar sensor covered with a cloth

      ∞ Ω

      I1-3 (TSP) - I1-1 (S5)

      Solar sensor exposed to electric light

      Except ∞ Ω

      I1-2 (TSD) - I1-1 (S5)

      Solar sensor covered with a cloth

      ∞ Ω

      I1-2 (TSD) - I1-1 (S5)

      Solar sensor exposed to electric light

      Except ∞ Ω
      Table 1. Text in Illustration

      *1

      Component without harness connected

      (Cooler Thermistor [Solar Sensor])
      Tip:

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

      If the result is not as specified, replace the cooler thermistor (solar sensor).

  2. INSPECT COOLER THERMISTOR (SOLAR SENSOR) (for RHD)

    1. U123673E02

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      I1-2 (TSP) - I1-1 (S5)

      Solar sensor covered with a cloth

      ∞ Ω

      I1-2 (TSP) - I1-1 (S5)

      Solar sensor exposed to electric light

      Except ∞ Ω

      I1-3 (TSD) - I1-1 (S5)

      Solar sensor covered with a cloth

      ∞ Ω

      I1-3 (TSD) - I1-1 (S5)

      Solar sensor exposed to electric light

      Except ∞ Ω
