Operation

Illumination operation

NOTE:

1. When the light switch is operated to the AUTO position with the ignition switched ON (engine off or on), a light switch AUTO signal is input to the start stop unit.

2. The start stop unit sends the light switch AUTO signal to the front body control module (FBCM) as a CAN signal.

3. The auto-light sensor detects the illumination level above and in front of the vehicle.

4. When the auto light sensor detects an illumination level of approx. 2,000 lux or less, it sends a TNS and headlight on signal to the front body control module (FBCM) as a LIN signal.

5. When the front body control module (FBCM) receives a headlight on signal, it turns the TNS relay and headlight LO relay on and illuminates the TNS, Parking light, and headlights.


Lights off operation

3. The auto-light sensor detects the illumination level above and in front of the vehicle.

4. When the auto light sensor detects an illumination level of approx. 4,000 lux or more for 1.5—2.5 s, it sends a headlight off signal to the front body control module (FBCM) as a LIN signal.
