Models 3 & Y Gen 4 ECU (necessary for CCS Capability)

[tps5352]

1. I do not (yet) have this part.
2. I do not need it.
3. It is (as of this post date) still available from a local auto dismantler. (Could be sold anytime.) UPDATE: It was sold.
4. Part # 1537264-00-B. It's the Gen 4 ECU that people with ~06/21-10/21 Models 3 & Y with buggered Gen 4 ECUs need to retrieve CCS capability, I believe? My understanding is that it's "plug-and-play" (or close to it) for those cars (but not for earlier, pre-2020 cars with Gen 3 ECUs).
5. Used, from a 2021 Model Y. (I cannot guarantee anything about the part or the source, but the claim is that it works OK and it is apparently a genuine auto parts business near me.)
6. They are asking $255 (so they must know it is sought after). Perhaps will accept less? Update: They accepted $240.
   
   
7. Note: My understanding is that these can be ordered (delivery perhaps delayed?) from Tesla Service Centers for less? (~$150?) So everyone should try that avenue first.
8. A used one like this would only be for someone with the right car who for whatever reason can't get one from Tesla, I guess.
   
   
9. If interested let me know your situation, and I can try to buy it and/or pass on the contact info.

I'd like to see this go to someone in need--not to someone who can easily get one from a Tesla SC. (Hopefully no one does need it, and everyone can get a new one directly from Tesla.)

If interested, please PM (private message) me.

It was sold. But check with your Tesla Service Center. See Post #2, above. You should be able to order this part new for just $140.

@tps5352 , Thanks for sharing this. I have the part on order now with Tesla. My MYP falls in that window without CCS unabled (Sept 2021).

I heard from my Tesla SC that they don’t have a solution for my MYP Sep 2021 yet and moved my appt date out about a month. Will let you all know what i hear.

If you can get the part, you can swap it yourself. It takes about 30 minutes.

Though you do have to either have an update pending, or get the vehicle into service mode, so you can update the software. (car will not drive or charge until it rectifiés the hardware/software discrepancy)

The part shown above was to address an earlier generation of Model 3/Y from 2018. Do you know the part number required to update the 2021 Sept (refresh) model Y?

I believe that Part Number 1537264-00-B from Original Post #1 above is the correct Gen 4 ECU for 2021 cars that have (or want to have) CCS compatibility. This is the part that people are trying to order from Tesla or buy on eBay. See Post #2.

If a (after February) 2021 Model 3 or Y lacks CCS capability, it was probably manufactured from 6/21-10/21 and outfitted with Part # 1537264-80-B, which lacks a key chip or something.

For 2021 cars I read that it is a relatively simple swap (1537264-00-B replacing 1537264-80-B) plus software update to add CCS compatibility.

Other ECUs were manufactured; for example, the Gen 3 Part #1092755-98-D for older North American Model 3s.

The CCS status can be fixed for those cars (see this), also, but besides the correct ECU it takes the "bundle of wires" and more DIY skills.

Research this carefully before purchasing or doing any work.

If you have a 2021 Model Y, and it shows in the "additional information" as Not Supported, then you have a stripped ECU, and just need to do the ECU swap, it's the same part, Gen4 Charge port ECU, 1537264-00-B

in your case, all you'll have to do is replace the ECU you have, with the new ECU, do a software update, and you'll be all good to go.

EDIT: You must already have a pending update waiting, OR put your car into service mode, BEFORE switching the ECU.

Does anyone have a link to videos showing the ECU install process and/or someone walking you thru the service mode steps after Ecu install?

 

[JulienWA]

This one is pretty close.

Please note that plenty of people haven't found it necessary to unplug the 12v and the "penthouse" before doing this work, but it does kill all power to everything so it's probably the safest way to do it.

I’ve scheduled a mobile service appointment to have this part ordered and upgrade done. Will see how it goes.

You scheduled what exactly? ECU charge port upgrade? or you asked for "CCS upgrade", everyone so far who has asked for mobile service to 'do it', has been denied.

ECU upgrade and part number

I thought I saw someone asked how much you were quoted for the part/install, but again how much did they quote you?

Also, as an aid to others regardless of whether you are successful or not, where in the country are you located (and what Tesla SC are you using)? Thanks.

Any updates on this?

Updated in Charlotte NC for 200.00 in service center.

I have applied for service for Gen 4 ECU upgrade and am waiting for the reserved date. (for Model Y July, 2021) I don't know if I can get this service from them. Has anyone ever had an ECU upgrade at a service center?

Interesting. I have only read that people are sometimes able to order the ECU with correct CCS-capable chip(s) (Tesla Part # 1537264-00-B) from sales/service, not that they could have it installed.

Please keep us informed of how things turn out for you.

Concerning the ability of North American cars to use a Tesla CCS adapter, for Models 3 & Y there seem to be at least three scenarios:

1. "Newer" (early 2020 and later) cars with "correct" Generation 4 ECU (# 1537264-00-B). CCS-enabled and no retrofit required. Ready to use Tesla CCS1 adapter.
   
   
2. Newer cars with "stripped" Gen 4 ECU (# 1537264-80-B). CCS disabled. Retrofit (relatively simple ECU swap + car software update) required.
   
   
3. "Older" (pre-2020) cars with Generation 3 ECU (e.g., # 1092755-98-D). Not CCS-capable. Retrofit (ECU swap, wiring modification, software update) required.
