Sorry, was away for the past week.
Thank you for all your replies.
Hi Kelvin, nice to get to know another fellow malaysian. I got it from a university friend of mine in Kiev, who bought it there and shipped to me. Regarding the mods that they were talking about, i think its changing the ECU for the charge port. So, if you have the Gen 4 ECU (part number P1537264-xx-x, picture in orginal post) for your Japan Unit, then welcome to my boat.
If you have the Gen 3 ECU for the charging port (Part number P1092755-98-B), then you need to swap the ECU before you can use the CCS2 adapter. I read there are 2 ways to do this:
1) you can either get a GEN 3 ECU part number P1092755-82-B and swap it -
@wlee thread on it
or
2) You can get Gen 4 ECU part number P1537264-00-B plus a bundle of wire to get it working.
@FalconFour thread on it
Regarding PM you, I dont mind at all if we are sharing private information like our contact numbers. But for the sake of community, if we have something technical, I think it is better to discuss in the open. It helps our community to grow, esp to New Zealanders who some also uses Japanese imports
@FalconFour, thanx for your input .
That line's "missing-ness" is definitely regional - I've heard that from other people in other regions as well. The presence/lack of "CCS adapter support" doesn't indicate anything by itself - it's just a visual change. The support/lack of support is still there based on the installed hardware.
I think and hope is visual change too. Because i downloaded the CIrcuit Diagram of my Model 3 version (early 2021, Shanghai Giga) off Tesla Service website
Tesla Service from both Japan and North American site (the 2 pdfs below), and both have exactly the same diagram.
That means you have a port that looks like this, right?
Yes, I think it is safe to say up to 2022, all Tesla cars from Japan uses the Tesla Proprietary Charging (TPC) port as your picture. Hence why I thought most ECUs and mods to this M3 is closer to NA than Europe.
Regarding the CCS adapter, I am using TPC to CCS 2 adapter, as pictured here...
Thus, when you have a car that's expecting CCS1, it expects things to behave a certain way. For CCS2, that seems to be that the Proximity signal is slightly different between the two. The adapter (from CCS2 to TPC) would need to properly adapt the signals.
So, you are saying that possibly, that the P1537264-00-B ECU that I have should work for CCS1, but may not work for CCS2? It makes sense as the Tesla's in Europe with Gen 4 ECU are using P1537264-20-B ECUs.
However,
@kaalrok stated above that despite using P1537264-00-B, after and update an a change of non-Plaid version of the CCS 2 combo, he managed to get his MY to work. Thanks for your input
@kaalrok, i didnt know there were plaid and non-plaid version of the CCS2 adapter.
Therefore, I have list down the potential cause of my error (Missing CCS line and error in cahrging via CCS2), and will work on one by one
1) The CCS2 combo adapter is broken or wrong version (Plaid/non-plaid)
2) ECU P1537264-00-B can only charge CCS1. For CCS2, will need P1537264-00-B, and the CCS2 adapter
3) True Region lock, and not just a GUI bug - for which I dont have any idea on how to unlock the region to allow CCS2 charging
So, my step-step plan is
1) to get another CCS2 adapter and try again - maybe the non-plaid one will work
2) if #1 dont work, get P1537264-20-B ECU, swap it and try with both CCS2 adapter
if neither work.. i hope someone can give me some ideas
Of regarding service mode, unfortunately Malaysia is a non-core market. The nearest service center is in singapore, therefore i do not know how to get into service mode since the service center in a neighbouring country. I can use Tesla diagnostic Tool box, but at that price, I will keep this option lower down.
Ive ordered anothe CCS2 adapter. I will update all of you once i received and tested it.
