fog light kit not working tried everything

[Logan1116]

Hello, I have just installed new fog lights on my 2023 ralliart using the existing wiring. I have installed the relay and checked the fuses and also programmed the ETACS with the door open and shut process. The switch works on the stalk because when I turn it on the last step of programming the car beeps for 3 seconds like it’s supposed to but the fog lights don’t come on and the light on the dash does not illuminate. I’m pretty sure I do not hear the relay clicking either. Any help with this problem would be greatly appreciated!

... also programmed the ETACS with the door open and shut process.

How did you do that?

Did you use the MMCodingWriter app to re-program the ETACS-ECU?

You’re supposed to be able to reprogram the ETACS by putting on your seatbelt then starting the car, opening and shutting the drivers door 5 times under 10 seconds and then turn the fog switch and that will program everything to work… but it didn’t. I didn’t know there was such an app like that I’ll look into that when I’m back home I was just going to take it to the dealer so they could program it but I wanna avoid that.

Is there also a fuse that has to be installed? I really don't know....
I found this procedure, not sure if it's the same or not? https://mirageforum.com/forum/showth...ll=1#post97167

I checked all the fuses related to the fogs only thing I need to double check is if the rear fog light fuse is there idk if that is related to the front fog circuit or not. Also I read that thread too and that is the procedure I tried but to no success ://

Are the lamps OEM? I assume so.

Perhaps the relay is incorrectly positioned. Or perhaps re-program the on-and-off switch to have it off,
Unplug and plug the lamps and then redo the switch program just to have it enabled? I assume the lamps are already installed and plugged correctly. I had similar hiccups from my 1st G4 and eventually got it working this way myself.

Yes, they are oem. The housings are knock offs but the wiring was already in place and I hooked up nice sylvania bulbs. I’ll try programming the switch back to off and then on again and I’ll update after. Dealer is going to charge 165 to program the switch

Understandable. Hope it works this time.

If it still fails, as a last resort, maybe you can take a look at the ETACS setting using MMCoding Writer and verify that is set to "Present"

no need to reprogram the etacs you can activate it directly on customization function on Etacs by using MUT iii.
