Solar Sensor: Inspection: Inspection
WARNING: This page is about a different variant/trim than selected.
- INSPECT SOLAR SENSOR (AUTOMATIC LIGHT CONTROL SENSOR)
- Disconnect the solar sensor (automatic light control sensor) connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition 6 (CLTB) - 3 (CLTE) Power switch off Below 1 V 6 (CLTB) - 3 (CLTE) Power switch on (IG) 11 to 14 V TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Solar Sensor (Automatic Light Control Sensor))If the voltage is not as specified, repair or replace the wire harness or connector.
- Reconnect the solar sensor (automatic light control sensor) connector.
- Turn the power switch on (IG).
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition 1 (NSHA) - 6 (CLTE) Sensor is exposed to electric light 0.8 to 4.3 V 1 (NSHA) - 6 (CLTE) Sensor is covered with a cloth Below 0.8 V If the voltage is not as specified, replace the solar sensor (automatic light control sensor).
TEXT IN ILLUSTRATION*a Component with harness connected
(Solar Sensor (Automatic Light Control Sensor))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 6 and the negative (-) lead to terminal 1 of the solar sensor (automatic light control sensor).
- While using the auxiliary 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 (automatic light control sensor).
- As the inspection light is moved away from the sensor, the voltage decreases.
