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

- 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.
