Hi dan, This was kinda of an old post, nevertheless, I appreciate your answer. We know now how to get / clear DTCs via CAN for HVECU and HVBATT, but there...
The diagram in CANSchematic.jpg is correct. Only those devices are directly on the CAN. Other devices report to the CAN through the gateway (mostly from the...
... Hmm. Looks like this was already done. The technical info folder has the list of ECUs and the network they are attached to. Only addition I will look...
... I assume you mean on an NHW20 car. Not much investigation has been done in this area. However, it may not work because the Mark II Mini- Scanner uses the...
... Roughly how many DTCs are listed in there ? Can you reply to vass.attila@... as well, please ? ... Sending 0213B00000000000 to 0x7E2 and sending...
Under the 'air bag' chapter of the diagnostics section of the service manual, the following is stated: The HV ECU uses the ISO 14230 and ISO 9141–2 for ...
... Both ISO 14230 and ISO 9141-2 use the same signaling and coding. Signaling is floating the medium towards battery voltage via a 510 ohm resistor for...
Ladies(?!) & Gentlemen, With a big help from GregH, we finally have DTC aquiring and clearing via CAN ! I was able to get/clear DTCs for ECM, HV ECU and HV...
Congratulations Attila and secret CAN decoding team! Primo "Prius", deinde caelum! (sorry for the poor Latin, and the worse theology!) On Fri, 05 Nov 2004...
It's been kind of quiet here lately, huh? What's going on with schematic capture? I'm totally uncomfortable doing this before we've discussed what we're going...
Hi folks, I work with Umetrics - the Multivariate Analysis experts. Right now, we're kicking around doing a PR stunt by hooking up their online multivariate...
Hi Joel, ... What are the goals for this PR event? I've found, that the control system in the Prius is quite well-balanced (no surprise there), parameter...
I've been asked lately from several places ( including priuschat.com ) if my solution is for sale. I keep tellin'em, that the Mark3 is coming soon. Me not...
Just joined this group and am interested in helping if at all possible. In reading this post what caught my attention is the Palm option. I have been a...
Hi everyone - I have been working 12 to 14 hour days for the last month. But to top it all off, the company decided to close our local office, so I had to move...
I'd love to help, but I don't know what needs being done, or how to do it. Nobody is updating this site with files, such as new codes found, preliminary...
... I think this is why we're stuck. There isn't enough stuff in place at the higher levels of abstraction so that people can take away chunks and work out the...
I hope I'm not out of line, I just joined today and I'm excited about this forum's project. However... is it about to flounder? May I digress? Sadly, just...
... This project can't be all that complicated. I'm talking about the MCU. Serial communications, some processing, spit it out to a LCD, and monitor a couple...
This is an interesting chip that might be of help for in writing the code. http://www.ozenelektronik.com/upload/data/oe/oe91c1600.pdf It simulates a Electronic...
So, does this mean there is a standard for encoding (and requesting) EODB information on the CAN, including freeze frame data? If that's the case, that would...
... I have certainly seen indications of this, but have not gone deep into it, as I did not find an immediate need for this. Greg mentioned, that if he sends a...
... diagnostics ... I just started playing for with my recently acquired THHT for a few minutes today, and it turns out that many of the ECUs do not use CAN....
Wow! Great! How much did it cost you? When you say you don't have the CAN adapter, are you referring to the adapter for the THHT? If so, then you can...
... Too much! ;) The new price from OTC is $2996 for the diagnostic kit and $619 for the CAN module. There is another one on e-bay (item number 4511285565...
... Has anyone decoded the protocol for the other buses? What do the other buses look like electrically? Are they also differential signaling (based on the...
By Other busses, are you referring to BEAN and AVC? BEAN is a single (not differential) wire ring network, and AVC is differential star. CAN of course is...
Very happy New Year to all the MkIII miniscanner wizards. I have a question that you may already have answered by CAN-sniffing: Does it seem that the 2G Prius...
