(a) Connect the positive (+) lead of the battery to terminal 6 and the negative (-) lead to terminal 3, and 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 subjected to electric light

0.5 to 3.0 V

1 (TSL) - 3 (CLTE)

Sensor covered with cloth

0.5 V or less

2 (TSR) - 3 (CLTE)

Sensor subjected to electric light

0.5 to 3.0 V

2 (TSR) - 3 (CLTE)

Sensor covered with cloth

0.8 V or less

HINT:

  • As the inspection light is moved away from the sensor, the voltage increases.
  • Use an incandescent light for inspection. Bring it within 30 cm (11.8 in.) of the automatic light control sensor.

NOTICE:

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

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