KDM style DRL for 2014~2015 genesis?

[dakagez]

Posting what i found in korean website about how they got a north america version genesis to have KDM style look - had to change headlight & BCM.


According to the shop that installed the KDM headlights, they had to not only change the headlight itself but also had to change BCM Box(I don't know much about cars, so I have no idea what this is, but it seams to be something that is behind the fuse box).

For your reference, below is the link that I've got the information. It is in Korean, so I suggest you use google translate.

Below is also a pic of new G80 sports

It is confirmed that the new G80 headlights would fit on the current generation genesis but I have no idea on the wirings.

BCM = Body Control Module

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by a physical relay, and fuse connected by physical wires that can be rerouted and thus change how the lights works has been replaced by integrated circuits on chips that incoporate the old relays and fuse function in them.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 had no idea that CAN bus had gone that far on the Genesis (used for body control). Not surprised though considering how much copper can be saved. I did CAN bus solutions for industrial control systems (but mostly MOD bus) when they were used lightly in vehicles. For a laugh, everyone on the forum should take a look at an early 80s car and see how much copper and connector blocks there are just for the ECM.

Larry, sounds like your background is engineering or heavy tech. Welcome to the forum. We need you.
