Just upgraded to a 2014 GX460 from an FJ cruiser (Hence the name). I was wondering if there is a way to run the Fog lights with the DRL LED combo on our 2014+ Lexus GX460s? I like the look quite a lot and don't want my main low beams on all the time in the city when the DRL + Fog light combo would be enough around town.
Is there a way to access the OBD settings using a higher end diagnostic tool to enable the fog lights to turn on when only the parking lights are activated?
Lexus light control ECU units are hard coded non programmable. You can always re-wire the fog lights to on with DRL by adding some trigger relay to power the fog lights. However, the potential issue you may facing could be the error massage in cluster associated with fog lights.
I see. I would think it's a similar process with Tundra. Hopefully someday someone did
What was the process with Tundra?
Technically you can add a relay/logic relay that would be activated by DRL on and headlamps off, this would send power to the fog lamps, then when headlamps comes on the relay wodul deactivate and revert fog lamp control to the switc.
