Anyone know some quick troubleshooting tips for the Auto Headlight function not working? (2014 IS350 F SPORT)

Lights function normally when cycling through manually, but wont turn on when its pitch black out.

the last things done to the vehicle was a Remote start (Fortin) was installed, and i installed some fog lights... maybe some wiring under the dash related to the auto sensor?

thanks,

 

I think there's a light sensitivity setting in the settings. You can try playing with that, but it sounds like there may be something funky with your wiring.

 

Yes I'm leaning towards a wiring issue, just wondering if someone has an idea where to look first. Maybe a wiring diagram or info if there is a fuse for that function.

 

Problem solved!

I contacted the installer and he said he had to remove the old starter which had random wires poking about so he cut them (all the added on wires). I went back to the steering wheel stalk and found the problem... The old system was put in series with the auto lights... Pink wire turns to blue at bottom left...
Other side of pink connection spliced with white. I just connected the white and blue. All good

 

what kind of installer just cuts random wires!??!!!

 

they weren't random. He said they were from an old starter system. Sounds like whoever installed the last starter system did it wrong, and the new installer assumed that it was done correctly the first time.

 

Yep, the old system was some Frankenstein thing with the old way where you stuff a spare key in there. I did like that it had a take over function, but now i can control it with my smartphone. The system acted up and stopped working so the new installer suggested replacing the whole thing.
