SOLAR SENSOR INSPECTION


  1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR (SOLAR SENSOR)

    A01EOB6E47

    1. Connect the battery positive (+) lead to terminal 6 and the negative (-) lead to terminal 3, then measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      1 (TSL) - 3 (CLTE) Sensor subject to electric light 0.5 to 3.0 V
      1 (TSL) - 3 (CLTE) Sensor covered with a cloth 0.5 V or less
      2 (TSR) - 3 (CLTE) Sensor subject to electric light 0.5 to 3.0 V
      2 (TSR) - 3 (CLTE) Sensor covered with a cloth 0.8 V or less

      If the result is not as specified, replace the automatic light control sensor.

      Note

      The connection procedure for using a digital tester such as a TOYOTA electrical tester is shown above.

      Tech Tips


      • 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.
