I haven't seen any dbc files for the instrument bus, but in case you haven't already found it, this post links to the most complete description of the messages on that bus that I am aware of.

Yes there is more to wish for such as the source code for the firmware and more schematics (PEM and switch pack are high on my list). However, I am grateful for the stuff they already published.

I intended to try just now, but couldn't even find the white connectors. I have the shrouds off, but the connectors are nowhere to be seen! Any suggestions?

I don't know, but in essence I would think so regarding Tesla. Apart from choice of software versions and some tweaking of the distribution content it is hard to see the value for them in distributing something else. Others here may know.

No it is not the same as the GPS-corruption cable. You need to connect the PC to the can-bus no 4. The published Tesla documentation specifies that one should use a PCAN-USB adapter (Tesla part no 1016990-00-A) and a 4-way breakout cable for the diagnostic port (Tesla part no. 1013716-00-A)...

Yes, it is great that they did this. From what I can see, the new stuff now is software for updating firmware, the firmware itself, dbc files (battery and PEM) and a collection of diagnostic tools. They previously published a document on the battery at the same site. There are several...

A quick look suggests that the link "Diagnostic Software" is new compared to what we have observed before. It points to a github repository. I found dbc files for the PEM and ESS in one directory and diagnostic software in another. The latter appears also to contain all the firmware. Some of...

I am not sure I quite understand the problem, but perhaps this thread can give you some clue on what is involved: Chargeport Micro Switch problem

@phirephoto could you please take this to a shrink, a Leaf forum or somewhere else where it doesn't distract those of us who are actually interested in Tesla Roadsters?

I am not a "shocks person" either, so I can't say much about how they work. The standard shocks on the sport model have these external reservoir cylinders on the front. So regarding your second question, here you can see how these standard shocks are mounted:

No, that leaves some parts still powered. Pulling the plug disconnects the battery entirely.

In this circle BMS usually means battery management system, i.e. the electronics that monitors and controls the state of a battery pack. The boards in question here are actually referred to as BMBs, battery monitor boards or battery monitoring boards, and as far as I can tell mainly monitor...

PM sent

I got a new one at the Tesla service centre about two years ago.

Does anyone know why the pumps in 2.x cars have separate part numbers (2005512 and 2005514) in the parts catalog? The two pumps appear to be the same from what I read here.

On my Android phone it is in a menu on the upper right hand side of the car screen.

There are torque values in the service manual: Roadster Service Manual | Tesla

Check "Article #21615 - SWP 420 SWP: APS off, but no pulse from BPS" in https://service.tesla.com/docs/Public/Roadster/Toolbox_Articles/Roadster_Alert_Articles.pdf

I recently had the same issue as the OP with the charge port switch not connecting anymore and decided to fix it myself. In order to get to the switch, I followed the procedure in the service manual called "Light Ring Assembly - Charge Port". It is rather involved, but mostly straightforward...

The color is mentioned here: Roadster paint colors but not with definite conclusions.

Welcome! I am looking forward to the crazy story. I am curious about your car as I tried to make a list of Tesla Roadsters in Norway some time ago based on public sources which are somewhat limited. Perhaps the roadster historians here also would like som info on it. @hcsharp makes the CAN...

If your VDS also shows the wrong date, i suggest that it is the GPS-rollover issue: Caution - Annual Service - Car power-down - GPS issue

To question 0, these are the circuit diagrams published by Tesla: Roadster Circuit Diagrams Connector information is also there: Roadster Connectors

Looks like it can download and "localize". So yes, maybe that is an answer.

The user manuals and toolbox articles are downloadable as pdfs, the disclosed R&D documents as zip-files. Interesting stuff there on alerts to name one thing. There are also hardware details like schematics and pcb layouts. I haven't seen all of this in the wild before. The info under the...

More is published: Roadster Service Information

I have extracted the firmware from the unit that I did the can-bus injection on and looked for differences, mostly without considering whitespace, between what I had in my list and strings found in the firmware. Based on that, I identified and corrected minor typos that I introduced for end-user...

That fits my recent observation. The car has been in my garage for a while and the reported energy increased steadily towards 30kWh until I drove it today. The increase when parked was somewhat less than 1kWh per day. When I parked it again it reported 0kWh on start of the charge and 3kWh after...

Here you can see it in the car: Service disconnect

I have 195/50R16 in front which is a recommmended alternative to 175/55R16. On the rear wheels, I have 225/45R17.

Sounds good to me!

Of course, if we are not concerned about the length of the message texts in the OVMS, we could have both joined into one marking the two parts. e.g., E: and D:.

Yes, exactly. Apart from finding it interesting, it is the likelihood of becoming "service" myself that motivates me to dig into technical aspects of the roadster. The current OVMS-implementation with the messages stored in a file on the server can only handle one message per ID. That is why...

I think the debug version of the messages are usually to be preferred. First of all because many of them do not have enduser counterparts and it is frustrating receiving a push-notification without any idea about what is wrong. Second, for some ranges of IDs all enduser messages are equal while...

These are the messages that appear on the VDS screen. I only used the OVMS as a tool to inject CAN bus messages that the VDS responds too. I could have used something else, but the OVMS is a very good tool for the task. You can think of my list as a verification and completion of the lists on...

I have now verified all known codes using CAN bus-injection and summarized the result in the attached file as information to those who may be interested. The debug messages were largely known and contain less news, but I now got all the enduser messages and message color codes too. Since these...

Thanks, I will get in touch. Since my posting, I have been through quite a few message IDs filling in gaps in the information on the hardcoded messages, in particular message color and enduser-message texts.

I am having a go at the can-bus injection method mentioned above. I am using the VDS from a salvaged car and an OVMS-module for the investigation. First I toyed around issuing "can can1 tx standard 100 93 01 B3 B4 00 00 00 00" to raise an alert and "can can1 tx standard 100 93 00 B3 B4 00 00 00...

The sticker says "CHROMA P/N:". Chroma seems to be a global company with a headquarter in Taiwan and roughly the right business area. Could that be it?

I think it might be a Ford part no. AM64-19D623-AB

I finally decided on A052 on my car and had them on this summer. They are fantastic compared to my old tires (AD07 front, Michelin Primacy 3 rear) with aged rubber. Road noise is strongly reduced, the drive feels much smoother and as far as I can tell without having tracked the car, I don't do...

Regarding temperatures on the VDS screen: Charge Thermal Limit warning

Good to hear that your car works again! I wonder what made your IGBTs fail?

Perhaps not crazy, but is the idea right? Even if you can get your hands on a bricked roadster, it will hardly be inexpensive. The only time I have seen one for sale, the asking price was about 60% of the typical asking price of a fully functioning one and probably 75% of the lowest asking...

OK, understand.

Interesting. In the advertisement there is a seller's statement ("Selgers egenerklæring") that the car has not had a major collision damage ("Bilen har hatt en større kollisjonsskade: Nei").

Did you try these? If so, what can you say about them?

What about AD08 on the rear wheels, and Yokohama 701 or 105 on the front wheels in an attempt to get a bit closer to the recommendation?

Thank you. I am note sure that they deliver in my part of the world.
