Headlamp Alignment Sensor: Testing and Inspection

AUTO LIGHT SENSOR INSPECTION

NOTE: Inspect the auto light sensor from the back side of the connector with the connector still connected.




1. Measure the voltage at auto light sensor terminal A and verify that the voltage is 5 V.
2. Shine a fluorescent light or expose the auto light sensor to natural sunlight.
3. Connect the positive (+) lead to terminal B and the negative (-) lead to terminal C of the auto light sensor, and verify that the voltages are as shown in the table.
- If the voltage is not as specified, replace the auto light sensor.
