Fog/Driving Lamp: Description and Operation

FOG LIGHT




GENERAL DESCRIPTION CONCERNING FOG LIGHT
The following ECUs affect the functions and control of the foglights.




FOGLIGHT
If the ETAS-ECU sends a foglight "on" request signal to the front-ECU after the low-beam headlights are on, the foglight relay is turned on, allowing the foglights and the foglight indicator light to be illuminated. If the low-beam headlights is turned off, the foglights will also be turn off automatically. Therefore, if the headlights are turned on at next opportunity, the foglights do not illuminate.

If the high-beam headlights is turned on while the foglights are on, the fog lights will be turned off. Then, if you switch the headlights from the high-beam to the low-beam, the foglights will be turned on again.

NOTE: This description covers the foglights only. In actual driving, the foglights may be turned off due to the headlight automatic shut-down function. For the details of the headlight automatic shut-down function, refer to its Section.
