This looks promising! Good price on the used BCM too. Let us know how it went. I assume you have the schematic for the heated steering wheel system.
Are Elantras popular in Ukraine?

The price is good, but due to the coronavirus, delivery is very expensive, it is even more than the cost of the BCM. Yes, I know where to get schematic heating for the heated steering wheel system, but these schematic for the European market Elantra, will they be very different for cars from the USA and Canada? Elantra is very popular in Ukraine - and I am very pleased with this car, before Elantra I had another car, also Hyundai, but it was an Accent.

I have EU variant schematics as well and I can confirm they are the same, when it comes to connector blocks (at least the ones I worked with). When it comes to engine harness, for example, that is where things are different due to different engines. Good luck with the project!

BCM (2017 production year): 95400F2090
GsiTurbo

Can you please tell me, is this comfort unit, as I understand it, suitable for many cars? I already wanted to order and found that on the site where you ordered, the description says that it applies to Hyundai Sonata. Wouldn't that be a problem?

The TPMS menu in the dashboard has to be activated via GDS or another tool, such as Can Hacker.
Today I got a Can-hacker and I was able to activate the TMPS function on the Canadian dashboard in which it is disabled. There is nothing difficult about this.

I see that can Hacker has evolved. Last time I have seen it, it was just plain PCB (printed circuit board). Yes, it is easy with this product, one just has to tick the option and voila. Definitely easier to do than with the GDS.

BCM is good to go. Few parts for Elantra I ordered from this website did show that part belongs to Sonata.

Did you still need to get the BCM in order for the TPM to fully function?. or was hacking the dashboard enough to activate the TPM ?

Thanks!
I have an American Elantra and the TMPS function is already provided in the BCM. I only needed to activate in the dashboard.

Hi gjurza.. Hope you dont mind me asking.. But what version of software from Can Hacker did you use?.. And I checked out CAN Hacker website and their online pictures of the CAN HAck interface looks very different from yours....

Thanks alot!

Hey all, I'm just starting to look into doing this so I was super happy to find an active thread on the subject. I have a Canadian 2018 Elantra GT Sport (6MT, with heated steering wheel) and am moving to the US. The car looks like it meets all US regulations except for the TPMS.

Could someone please confirm what the least painful way to do this is?
  1. Purchase BCM (which one?)
  2. Purchase 4x TPMS
  3. Take to a Hyundai Canada dealer to code them. (Can the CAN Hacker do this too?)
Is this roughly correct?

The easiest option would be to purchase BCM from US specs variant of the car - it will need to have ALL SAME FEATURES (heated and or ventilated seats, heated steering wheel, BSA, parking sensors etc) as your Canadian variant. If not, you will need to purchase new BCM from Korea. Since Elantra and i30 (aka Elantra GT) are two different platforms, my info on BCM does no apply to your vehicle. For this, you would need to contact someone on FB group that has KDM variant of the car.
Any reputable tire shop will code TPMS sensors.

If I purchased a BCM from a US Hyundai dealership, would they not be able to re-program it to enable those features? I assume they don't have a different part number for each possible configuration of the vehicle.

Also, am I correct in understanding that if I purchased a US BCM I could use it as-is if I'm okay losing the heated steering wheel and BSMS while it's installed. I would be okay with that for the time being.

I'm just bit short on time so I'm looking for the fastest way to get the TPMS and have the car imported and I can worry about figuring out all the details later.

No, while various Elantra generally share the same harness, features are controlled by the BCM. It is not possible to activate features on a BCM that does not support them.

Why don't you just purchase a stand alone TPMS system off Amazon? Such as this one: Tire Pressure Monitor System Car Tire Pressure Monitoring System Car Tire Pressure Sensor Universal tpms Tire Monitor Installed on Window Pane with 4 External Sensors for Cars SUV Trucks RV, Tire Pressure Monitoring System (TPMS) - Amazon Canada
Would this satisfy US authorities?

Okay that makes sense- cannot enable unsupported BCM features. Do you have an idea if I installed a stock US BCM, whether that would work for at least the TPMS and the features that were originally available in the US market vehicles? I understand I'll lose any features (heated wheel, BSMS, etc.) that the part didn't support, which I'm okay with as long as the car will still operate fine and I can get it across the border.

Unfortunately, aftermarket will most likely not satisfy them. While some people have gotten away with it, according to the rules it must be OEM parts installed by the OEM.

In theory it should.. Why don't you try and let us know. Find BCM that will support as many features as you already have, including smart key.
