2015 -> 2016 DRL LED changes

[Seattle Genesis]

Hello y'all,

so I heard there is a way to change the 2015 DRL LED lights to look like the 2016. It seems there is a software code change. Not sure where this is and if its only a setting in the technical menu. Ive heard the dealer can make this change, but I'm not sure of the cost if any. I'm going to the dealer next week to see if they know anything about this and if they will do it. If anyone else knows anymore about this please post here.
Thanks,
Seattle Genesis

BTW. Ive only seen a few Genesis in the South Seattle area. I went to Florida for a week and they are everywhere. Both old style and new style. In that week I probably saw about 15-20 different Genesis'.

Let us know how you make out with your dealer...

Interested in this also!

I hate to burst your bubble, but this is NOT just a software code change - it is a wiring change.

As detailed in the posts below, my 2015 was missing a wire in the harness (in pin position 12 in the headlight connector = DRL). My 2016 with LED Brow DRL's has a wire in this position.

But, if one simply wanted the intensity of the LED brows when in parking light mode increased to 2016 LED levels, could that be under software control?

I'd guess so - though I doubt Hyundai will be of any help with that and it is non-stock programming...

you didn't burst my bubble.. As usual I'm only searching for a way to make something happen. Also the internet is full of truthful claims. I'm still looking for a solution and maybe there isn't one. I wont be buying a 2016 for LED DRLS.... LOL

Have you guys heard of shops that do stuff like these guys? http://elstiggarage.com/

Looks like they do custom headlights and can do anything you can think of. Not sure how they do it or what the cost might be, but it shows things are possible.

No offense was intended - was just setting the record straight as I had looked into this last year and discovered it's a wiring difference.

Thanks,

I didn't buy a 2016 either

were you able to find out what Hyundai dealer had to say?

Below is a post I made in another thread on a similar subject that IMO seems germane to the discussion here Sooooo.....

FWIW the best as I can tell the lights (Fog, DRL, etc.) are all controlled by the IPS control module in the IGPM which is co-located with the passenger fuse box behind the driver's lower crash pad and not thru the BCM which is located on the passenger side behind the glove box. The various lighting configurations are encoded in the B-Can data stream which for the most part is encoded in the multi-function switch ECU then transmitted over the B-Can to the IGPM which then decodes the data and activates the various lighting circuits such as DRLs, Fog Lights, etc.

Also, at first glance it appears that things like the various lighting circuits wiring are common and what circuit is activated and at what level is controlled via the various control modules in things like the IGPM and BCM. What is unclear is if these control module programs are even accessable at the software level and might be fixed by say E-Prom H/W variants so modifying something like the 2015 DRL functionality to operate like the 2016s might be FAR, FAR more complicated and potentially near impossible or at least so costly that it's basically a lost cause to try and modify things.

I've seen many comments about folks thinking it might be done from a S/W change, but I can see no way that Hyundai would develop any approved procedure to do something like that since that would require a HUGE amount of effort on their part to implement/test/approve such a modification.

Finally, something IMO that is being overlooked here in all these lighting discussions is the old system of a lighting ckt being controlled by a physical relay, and fuse connected by physical wires that can be rerouted and thus change how the lights works has been replaced by integrated circuits on chips that incoporate the old relays and fuse function in them. The wiring connections and switches for the most part have now been replaced by an integrated data communications system (B-Can) with H/W nodes (i.e. control modules) integrated into various control locations such as the BCM and IGPM. Thus if one accidently damages by say sorting out a circuit it might no longer just be a matter of replacing a $.10 fuse, but might require replacing an entire major component like the IGPM/fuse box to the tune of hundreds with a total cost of approaching $1,000 or more not being out of the question. Thus mucking around with these systems can have a potentially EXTREMELY HIGH cost risk if one messes up.

I think starting with the 2015 Genesis and probably most other autos in the future the days of simple electrical mods are history and our options are going to be very limited in what we can do safely.

I would be happy to just have the LED lights on the 2015 be at the higher intensity of the 2016's. I understand the suggested complexity of trying to get the DRL's to operate with the LED's, but what about just increasing the voltage of the LED's when in Parking Light mode?

Without studying and doing some testing of the existing LED portion of the parking lights function I can envision a fairly simple way to do what you want. It would require cutting the wire to the LED strip on each headlight assembly and inserting a relay that would be activated by the stock LED signal voltage and then provide a full 12V or whatever voltage you designed into the circuit to power the LED. While simple in concept there are IMO several critical factors that need to be considered before one was to charge forward and start modding things. One that seems to be overlooked in a lot of these fog light installs on 2015s where folks are using these off the shelf 30/40A heavy duty relays that use one of the vehicle light ckts (usually the headlight) to activate the coil is I have yet to see one address the potential of damaging that OEM vehicle lighting ckt by not incorporating a "flyback diode" on the relay coil. As mentioned a lot of these lighting ckts are controlled by these chip/IC level IPSs which could be subjected to damage by the collapsing relay coils voltage spikes when the coil is turned on/off. A second consideration is to account for any "tell tale" monitoring ckt that might be employed in whatever lighting ckt your are modding or even tapping into.

I won't even go into the often misunderstood MMA aspect where the common misconception that your mod must cause the problem and that the manufacturer has to proof it. IMO for those that really understand what the MMA says and means they would appreciate the real problems that it can create warranty wise for those that mod their vehicles.

ON EDIT: One other thing I just thought of and not sure if it's applicable, but it might be that the intensity of things like parking lights might have a DOT specificied intensity that is different than DRLs and that could account for another reason that the LED strip in our 2015s in parking light mode are different than those in the 2016s when used as DRLs. This could cause issues if your state requires some sort of periodic safety inspection or even states when the vehicle is sold/titled. This is a total guess at this point on my part is only mentioned as a consideration.

Thanks for all the thought and effort on this subject. I'm in no way going to tinker with anything on this car. I'm not a hardware guy, I'm a software guy and I know my limits on both. Maybe there is an answer for the Genesis tech guys to figure out. Until I get a solid answer I will wait for the 2017 G90.
