Solar Sensor: Inspection

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT SOLAR SENSOR

Reconnect the connector to the solar sensor
Turn the engine switch on (IG)

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

Standard Voltage

for Driver Side

STANDARD VOLTAGE SPECIFICATIONS

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

for Front Passenger Side

TESTER CONNECTION AND SPECIFIED CONDITION

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

*1: for Driver Side
*2: for Front Passenger Side

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 negative (-) lead to terminal 1*1, 2*2 and positive (+) lead to terminal 6 of the solar sensor.
While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.

HINT

Use an incandescent light for inspection Bring it within about 30 cm (11 8 in) of the solar sensor
As the inspection light is moved away from the sensor, the voltage increases.

If the voltage is not as specified, replace the solar sensor.
