On-Vehicle Inspection [12/2019 - ]: Procedure
- INSPECT AUTOMATIC LIGHT CONTROL SENSOR
- Disconnect the G5 automatic light control sensor connector.
- Measure the voltage and resistance according to the value(s) in the table below.
*a Front view of wire harness connector
(to Automatic Light Control Sensor)Standard Voltage
Tester Connection Condition Specified Condition G5-1 (CLTB) - G5-2 (CLTE) Ignition switch on (IG) 11 to 14 V Standard Resistance
Tester Connection Condition Specified Condition G5-2 (CLTE) - Body ground Always Below 1 Ω If the result is not as specified, there may be a malfunction on the wire harness side.
- Connect the G5 automatic light control sensor connector.
- Connect an oscilloscope to terminals G5-2 (CLTE) and G5-4 (CLTS) of the automatic light control sensor connector and check the waveform.
*a Component with harness connected
(Automatic Light Control Sensor)*b Waveform OK
Tester Connection Condition Tool Setting Specified Condition G5-2 (CLTE) - G5-4 (CLTS) Ignition switch on (IG) 2 V/DIV., 10 ms./DIV. Pulse generation
(See waveform)HINT:
The communication waveform changes according to the surrounding brightness.
If the result is not as specified, the automatic light control sensor may be malfunctioning.
