Is it still functional, to drive a few mph at least? Sorry I haven't been reading the thread

If so, would you do the honors?

She's fully drivable (not road legal, but still she can cruise).

She'd be a perfect test platform. And, if it doesn't work on her, I can try it on my 09 while sniffing the CAN bus to see if I can figure out a way to make it work. Thanks to my YarGauge development project I now have a fully functional homemade CAN bus sniffer.

I'll PM you my shipping address.

[Kioshi]

Lets hope it works on Crashy.
That be really nice if you could figure out to make it work on an 07 Yaris LB if the latter doesn't work.

Actually I have a gap in my schedule to ship out tomorrow, first thing in the morning. You should get it by Monday at the latest....

Thank you Scott.

Sir A.Y. Atoyot - i think CTScott meant from the perspective of looking at your engine bay standing in front of it. It is on the right from that view..

[CTScott]

Correct. I was thinking of your right or left as you are standing there with the hood open.

Friday Kioshi. But you don't need to buy me Lunch =)
I'll be on the 5th floor of the 7th garage parked near the stairs down. Although you'll beat me there you should park up there first.

For reference my car has 0 packages. It's completely bare bones.

Edit: Just saw you're about to ship it to CTScott. Texting you now just because we might as well try it in my car to make sure that it didn't just break or something. Might as well give it a shot before you send it off for a week or two.

The cluster is in CTScott's hands now.
advocate - my moron brother mailed it earlier...

Now the fun begins....

It arrived late this afternoon. I will give it a try in the morning.

[Kioshi]

hope it was packed good enough...

Ok, cool.

It was well packed. I hooked it up as soon as I got home tonight, but unfortunately with Crashy not having any lights, it was too dark to take it for a spin.

[CTScott]

I just tested it on Crashy, and the speedometer doesn't work either. She is an 08, with an automatic transmission and no ABS. The gear indicator does work, as you can see in the video below.

So, now to figure out how to make it work.

[Kioshi]

strange...maybe your assumption of it needing ABS could be true....

fingers crossed that the CAN bus can tell you how to bypass the ABS...

My CAN bus sniffer is proving very helpful. Last night I isolated all of the CAN bus message ID's (about 24 distinct ones on Crashy, who's an 08) to specific CAN devices. This requires unplugging all of the CAN devices except the ECM, and then plugging them in one at a time and sniffing the BUS.

I then sniffed my 09 (who has ABS) and found 12 additional message IDs. I haven't isolated the 09 ones to specific devices yet, as the devices are no where near as accessible as they are on Crashy. One of the new ones that I found on the 09 corresponds with one that someone doing CAN development on the Prius figured out to be the broadcast message of the vehicle speed.

So, hopefully tonight I'll have time to run my 09 on stands while sniffing the "speed" message to see if it does correspond.

If the 09 corresponds to the Prius broadcast message of the vehicle speed, what would that mean?

Isn't the speed some how related to the mpg meter on the Prius. I know on the older models depending on what speed you were cruising at, it corresponded to the mpg you would be getting....

The ECM gets the speed info and then broadcasts it over the CAN for whomever needs it (power steering ECU, etc.). The only significance to the Prius is that someone figured out that particular message. Other than the standard OBD protocol over CAN, there is little to no information out there, so it typically takes lot of work to figure out what data the messages contain.

Oh, i see, that would make it easy then. Hope it matches up to the Prius's code, seeing that they both use the 1.5 liter engine...

This cluster just went from being interesting to complicated in my head now...lol

[kustom play]

sounds like a lot of work

looks like it would of been better just to get the USDM cluter, its a bit more but at least everything will read out in MPH rather then KM.

I would buy a car with a swapped cluster that was in KM

It's definitely not a trivial swap, but the USDM ones with a tach seem to be pretty hard to come by.

Now that you mention the km issue, I realized that I can do the conversion in the data sent to the cluster so that 100 kmh = 100 MPH.

Jesus Scott now THAT'S impressive

I'm loving this thread!
