WARNING: This page is about a different car, the 2018 Subaru BRZ. However, it is still accessible from the selected car via links, so may be relevant.
- Inspection of the automatic light control sensor
- Sensor power supply
- Disconnect the connector D45 of the automatic light control sensor.
- Measure the voltage according to the following chart.STANDARD VALUE SPECIFICATION - VOLTAGE
Inspection terminals (Terminal symbol) Inspection conditions Standard value D45-3 (CLTB) - D45-6 (CLTE) IG OFF →IG ON 11 to 14V - Measure the resistance according to the following chart.STANDARD VALUE SPECIFICATION - RESISTANCE
Inspection terminals (Terminal symbol) Inspection conditions Standard value D45-6 (CLTE) - chassis ground Always Less than 1 Ω
- Sensor waveform
- Connect the connector D45 of the automatic light control sensor.
- Using a oscilloscope, inspect if a waveform is occurring between the terminals.CAUTION: With the connectors connected, perform this inspection from the rear of the connectors.NOTE: Match the oscilloscope settings with chart 1.PART DESCRIPTION
