2012-2015 Prius PHV: Custom PIDs for Torque Android App

I tested this yesterday after consulting with USB (thanks!) and I tried 4 PIDs on the way home:

State of charge (not the "all batt" one, that didn't work for me)
Coolant temperature (I did not get a reading/didn't work)
Engine speed (rpm) (I did not get a reading/didn't work)
Power Resource VB

I will try to do more testing to see which PIDs work based on what USB has told me.

 

Hi Tracksyde,

The PiP uses Li-ion battery so most of the PIDs related to HV battery will not work.

I can help to create a new list specifically for the PiP but I need some data to work with. I need to know the PID map and some raw values. I've created a spreadsheet just to collect the PID map. If you have time, download the spreadsheet and convert to CSV format. You don't need to drive the car, just put to READY and save the data to a log file.

Vincent,

So, put the CSV file on my MicroSD card, then load it into Torque and I'm guessing, log all these values? Sorry for such a basic question.. I'm not very familiar with Torque or PIDs and how they work.

Taking USB's advice, I'm trying some of the Gen3 PIDs, a few at a time (without logging). I didnt get to try it over the weekend, but I tried a few this morning on my way to work:

MG1 Revolutions (always negative of MG2 +/- a few RPMs)
MG2 Revolutions (works)
MG1 Torque (didn't get a reading)
MG2 Torque (works)

I left SoC on there, which works great (~85% full -> 23% when EV range runs out). I didnt note my starting SoC% this morning because the G1 is so slow to boot up. By the time I was able to start Torque, it was ~83% but I was about a mile from home (slight downhill, so there was already some regen).

I had tried Power Resource VB. USB actually told me to try Power Resource IB. But when I looked through the list, I couldnt find it. So I thought he meant VB. However, when I viewed the spreadsheet on my computer, I saw there was indeed a Power Resource IB.

So last night, I reloaded the CSV file and was able to add the Power Resource IB, However, when I turned on my G1 this morning, the display I had for IB said "ExtPID" and "not found". So when I got to work, I looked through the list again and it was gone. Reloading the CSV brought it back and I was able once again to add it. However, just checking my phone now, I see its gone again (I guess it disappears after I quit the Torque app).

Anyone have any ideas about that? Going through the list, I notice there are quite a few that will load with the CSV and then disappear (like a bunch of the other SoC ones, like max, min, delta, etc).

Driving to work, the only display worth watching today was MG2 Torque. When I take my foot off the accelerator, it goes to about -10.1 or -10.2 ft-lb. The highest I saw it go up to was 69 ft-lbs. But I wasnt constantly watching it during my drive.

The MG1 and MG2 Revolutions got up to about +/- 4900 or so. I didnt see it go past that.

 

Thanks, I've updated to 1.5.49, I guess that came out today? I also installed TorqueScan. I have the first 10 PIDs from Vincent's PHV list set up for logging too. I'll check it out at lunch in a bit.

 

I set up the logging on the first 10 PHV PIDs from Vincent's spreadsheet but it didnt log anything. None of my existing PIDs worked either. This is while I was driving to lunch (about 2 miles). When I left to go back to work, my traction control and ABS lights were on. Not sure what caused it but it must have been something related to my data logging setup (G1, ODB2 adapter, and/or Torque).

Also, I had TorqueScan installed and when I started the car (in Ready), nothing was really showing and it was near impossible to even scroll the list. When I tried the window popped up on my G1 asking me if I wanted to Force Close or Wait or Cancel.

I'll try again when I leave. I'm going to try uninstalling TorqueScan first to see if that may have been the issue, or part of it. I guess I should remove the PIDs I have displayed too.. but its such a pain to add them

I may be able to borrow a more recent Android tablet.. maybe that will help too.

 

Yes, after I got back to work, I removed the OBD2 adapter and confirmed the lights went away after starting/ready-ing the car again.

I'll remove all the old stuff and load Vincent's new list and try the Test button as you suggested. I should have some time after work to play around with this stuff today.

 

Yes, all those values consist of very long numbers, it would save a lot of time if it can be logged. Otherwise, you may capture the screenshots or write them down. The values are static so you just need to read it once. Unlike TorqueScan, which try various combinations to search for the extended PIDs and may take hours to find. Sometimes, you may get buffer full as reported in the PLX Forum.

Power Resource VB and Power Resource IB may not work because of different number of battery blocks and different voltage and current levels.

Vincent

 

That can't be right because the formula (AE * 256 + AF) / 10 cannot be greater than 6553.5.

I'm going to try and get an Android tablet from work tomorrow to try. But when I left for work today, I was trying the Edit PID/test and the first 3 I tried told me the formula was incorrect or something. So I decided to just add the first 4 PIDs into the logging section.

When I went to add the PID, I looked at all the PHV PIDs and they were all green (scrolling was really slow). This is good right? That means all those PIDs have some kind of data? Anyhow, I was encouraged by that.. so I picked the first 4 PIDs and entered them into the logging section. I started the logging and left work. About 10 minutes into my drive, I figured there must be some data, so I stopped the logging. When I got home, I checked the log and the 4 PIDs, I logged were all 0.

So at first I was thinking this is wrong. But then I thought, maybe the PIDs I picked (just the first 4 on the list) may have been related to the engine (the logged section was all EV only). Is that possible/likely?

 

Ok, I just went to go sit in the car and look through all the PIDs (on that screen when you add a PID). All the PHV PIDs were green. However, they were all 0. This was with the car in Ready.

So, what does that mean?

Also, I really think the G1 is probably not suited for this. The phone just seems extra sluggish when it is connected to the OBD2 adapter and the car is on. When not connected to the car, its not that bad. So I dont know if its the OBD2 adapter or the phone or a combination of both.

I had the "enable faster communication" turned on in Torque. But today (I guess with the newer version), it told me that I had data corruption and it recommended I turn off the "faster communication" setting.

 

The 1st 4 belong to 7B0 (Skid Control ECU) and as long as you're in READY, you should be able to read. Some PIDs are indeed zero since not every PID are used in the PID Map.

If you 're still getting formula error, you can try to break the PID into word-size or byte-size. e.g. do A * 256 + B 1st then follow by C * 256 + D or just do the A, B, C, D individually.

Vincent

 

Yes, it is supposed to be cube. Either change the formula to A * 256 * 256 *256 + B * 256 *256 + C * 256 + D or break up into smaller size. Either Torque don't understand "^" or there is a calculation overflow.

If there is a format for Torque to display in Hex. number, just ABCD will do.

Yes, you can try on GenII but use only 7E0, 7E2 & 7E3, the rest I don't think are applicable to GenII.
