So I've checked a few more things:
- I redid my PCS plug wiring to make sure the connections were solid, that's not the issue.
I'm not seeing any resistance across IPC CAN (pins 4+5 of the control board 12pin connector). Should there be a termination resistor here?
My PCS is P/N 1093219-10-G. Damien and Fred, what versions are yours? Could there be a version change causing the difference between Damien's and ours?

At first my pcs controller was completely dead, after 50+ mail to and from Johu we have solved the most critical functions, now everything works beside charging. That's the next headache.... I hope that we can solve this.
For the moment I use the outlander 3kw charger and dcdc
My PCS version is: 1133358-02-C
3phase eu 2018.

Ok, attached are three log files from the IPC CAN Bus. Included are:
- start up, without being plugged in
- plugging in and then unplugging in manual mode
- plugging in and then unplugging in Type 1 mode
Please let me know if these are usable/useful, it's my first attempt at CAN logging, the odds are high that I screwed something up.
Edit to add: charging did not occur in any of these instances.

In those logs I am not seeing any msgs from the PCS such as id 0x264 or 0x2A4 etc. That would suggest the pcs is not powered up.One little gotcha if bench testing is the case of the pcs must be connected to 12v ground and the big 12v terminals must be connected to a 12v battery.
take a look at some of the logs here :
https://github.com/damienmaguire/Tesla- ... r/CAN_Logs
to see examples of ids the pcs sends.

I think I have the grounds covered. I have the 12V connection, I have the casing grounded, and I have all the grounds connected on the control board.
Some part of the PCS must be waking up because I am seeing the correct HV reported in the web interface.
I will go through it again to make sure I didn't miss anything, but I'm fairly certain the connections are correct. One question though, the pinout lists 12V on pin 2 of the 12-pin connector, but then says "not used" next to it. Does that need to be connected to 12V from the car or just left unconnected? Should it be going to the PCS?

I did not use pin nummer 12. The connector to pcs dont have any pin to connect that cable.
Think that it get Gnd and +12v from battery terminals..
My messages from pcs controller wont start appearing until i enable input 1 and pcs controller is in manual mode. (Or type 2 mode if cable is inserted)
Som my first tough is that you nog get it to enable/run. But then you also see values appearing in web interface.... I did nog get any values there until I enable/run.

Ok so I have triple checked my wiring and can confirm that the 12V connections are getting 12V, the case is grounded, the control board is correctly setting pin 6 (PCS enable) to ground, and all other connections appear to be correct.
When everything is powered up, the PCS is reporting correct HV and 12V voltages, and the control board is displaying them in the web interface.
When I got the PCS, I did open it up and saw no outward signs of damage.
At this point, short of damage to the PCS that I missed or couldn't see, it appears from my end to be a firmware/software issue.

How can we do diagnosis? Do any of the messages sent BY the PCS contain some error code?

Message id 0x3A4 is the PCS alert matrix. It is a multiplexed message that will tell you all of the PCS's woes and complaints.
Byte 0 lower nibble flips from 0 to 1 indicating which message page is displayed.
Attached two pictures detailing the bits and their labels. The ones of most interest will be the "MIA" flags. e.g. page 0 bit 24 = hvpMia this means the PCS is not seeing a message or messages that should originate from the hvp (high voltage processor).
Now, all that is needed is for someone to transcribe this info into a dbc file and use it in conjunction with the CAN logs from the failed attempts to determine what is annoying the PCS. Then we can work on a solution.

Perfect, thanks!
Added some experimental code:
Code: Select all
if ((data[0] & 0xF) == 0)
{
Param::SetInt(Param::errbits0_0, data[0] & 0xFFFF);
Param::SetInt(Param::errbits0_1, data[0] >> 16);
Param::SetInt(Param::errbits0_2, data[1] & 0xFFFF);
Param::SetInt(Param::errbits0_3, data[1] >> 16);
}
else
{
Param::SetInt(Param::errbits1_0, data[0] & 0xFFFF);
Param::SetInt(Param::errbits1_1, data[0] >> 16);
Param::SetInt(Param::errbits1_2, data[1] & 0xFFFF);
Param::SetInt(Param::errbits1_3, data[1] >> 16);
}
So now all those bits can be found at the bottom of the page in errbitsX_Y where X is the page number and Y is the index. Y=0, bits 0..15, Y=1 bits 16..31 and so on. Please submit what you're getting when the PCS should be charging but isn't.
In this version I've also fixed the 2D/5D issue.

Did a quick test with the new firmware and the dcdc converter did not work this time, but we can skip that for now.. Lets focus on charger
Also read the can message. 0X3A4 @ 01 00 01 00 00 00 00 00
Getting error bit 16 on page 1, which would mean PCS_a73_unexpectedAcInputVoltage
according to Damiens matrix.
I have double checked that the voltage is not present before EVSE activate
Can it be that we enable EVSE Before the pcs get start sign from the PCS controller maybe?

Is there a housing like for the Zombieverter VCU, that i can order for this?

I found the other plugs as 3D printable options. But does this one exist, too?

I haven't found one. I bought a harness and pulled that one out of it.

I just realized that i bought an EU version of this charger. It's the EU version still not supported? Thanks Philip

There seem to be problems. The DC-DC converter works fine but not the charger. I'm hoping we can figure this out

Not a bad idea. Not sure if you bought it yet, otherwise just have it shipped here.

I'll get it shipped to you this week
thanks!!!!!
Hopefully i did not buy this without being able to use it
I didn't get the plugs printed, yet. But if you want to go for it I'll pay for it, of course

To explain once again : The problem is NOTHING to do with EU or US versions. It is related to the FIRMWARE version on the charger side of the pcs. I tested the controller on both US and EU versions before release. However, in the model 3 they change the can dbc with different firmware versions so the can that works on one charger (or indeed any other M3 part) may not work on another of the same type simply due to the firmware version that happened to be on the car at the time it was crashed/broken for parts.

Alright, added to wiki page.
So maybe Zapateros PCS just works fine then. Don't send it yet!

So just out of curiosity: if the firmware is not the correct one, what would be the solution then?

Simply finding the correct can messages for that firmware version. More that get found out the more pcs we will have working as the messages get added to the firmware. Wouldn't it be great if we all shared? Given that that won't happen then it will wait for me to get my new workshop setup, do it the hard way and publish the info.
