      (to Solar Sensor (Automatic Light Control Sensor))

      Disconnect the solar sensor (automatic light control sensor) connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      I61-6 (CLTB) - I61-3 (CLTE) Ignition switch off Below 1 V
      I61-6 (CLTB) - I61-3 (CLTE) Ignition switch ON 11 to 14 V

      If the voltage is not as specified, repair or replace the wire harness or connector.

      Component with harness connected

      (Solar Sensor (Automatic Light Control Sensor))

      Reconnect the solar sensor (automatic light control sensor) connector.

    4. Turn the Ignition switch to ON.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      I61-1 (TSL) - I61-3 (CLTE)*1 Sensor is subjected to electric light 0.8 to 4.3 V
      I61-1 (TSL) - I61-3 (CLTE)*1 Sensor is covered with a cloth Below 0.8 V
      I61-2 (TSR) - I61-3 (CLTE)*2 Sensor is subjected to electric light 0.8 to 4.3 V
      I61-2 (TSR) - I61-3 (CLTE)*2 Sensor is covered with a cloth Below 0.8 V

      Note


      • 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 2*2, 1*1 and the negative (-) lead to terminal 6 of the automatic light control sensor (solar sensor).

      • Do not bring the positive and negative tester probes too close to each other as a short circuit may occur.

      Tech Tips


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

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

      • *2: for RHD

      If the voltage is not as specified, replace the solar sensor (automatic light control sensor).
