Maybe it's time to change your setup... .

Have a look at AAAD and Screen2auto (for non-rooted devices). I can't test it - have got only rooted Android devices - but my rooted setup works without problems.

Bye for now Fred

Can you run something on the car screen different to the phone screen. I want my lap timer on the phone

 

[AP756]

Found no way to run two different programs on head unit and smart phone ,

Solution might be to use additional hardware like Carbotics Carplay2droid or CarDongle (klick on the names to visit web sites), both are "complete Android PCs" connected to USB (will report when I get my hands on one of these and can test them).

Oddly I appear to have lost my Boost/Vacuum guage in TorquePro last few days, all othe guages display fine but the Boost one appears to receive no data. I've not altered anything on the car or phone so I'm assuming it's something to do with the recent TorquePro updates? Anyone else having issues?

I tried with my non rooted phone with AAAD & Sceen2auto as well as AA Mirror without any success. I tried reinstalling Android auto and clearing the cache too. Still not working!

You're not the only one. Something changed within Torque and it lost contact to MAF/MAP sensors. Solution: Enter Torque Settings -> OBD2 Adapter Settings -> Boost Calculation Method and change to Prefer ALT. Worked for me (seems to show the boost value the ECU sees, bu

Thanks to https://gr-yaris.co.uk/forum/threads/oil-pressure-and-other-info-over-obd.4379/ we now know that selecting Toyota Camry 2020 in OBDLink Android app gives us access to additional sensors.

It is relatively easy to snoop Bluetooth traffic on Android devices from bugreports or even live. So I selected a couple of sensors in OBDLink on continuous monitoring and looked into the BT traffic using Wireshark. Here is a little snippet from the quite verbose conversation:

View attachment 21254

These are ELM327 microcontroler, that runs inside OBDLink, AT protocol commands. Interesting ones here are:
* ATSH 0007D0 - sets OBD header for all subsequent OBD commands
* 2162 - queries OBD Mode 21 PID 62 and gets 7D8 05 61 62 03 00 00 0 as a response

First three hex digits in the response (7D8) is the ID of the ECU that has sent the response. Next three bytes (05 61 62) I am not sure what they are. And next three bytes (03 00 00) is the actual data that could be interesting.

So here is the short list of OBD Headers, Modes and PIDs that I was able to figure out from the first initial look and from subsequent help of other forum members below:

Sensor	Category	Mode	PID	Header	Formula
This item indicates that the parking brake is "ON/OFF"	Navigation System	21	62	7D0	BIT(A:1)
Accelerator Position	Engine	221	059	700	(A-41) / 1.42
Engine Oil Pressure	Engine	221	074	700	(((A*256)+B) * 10) / 128
M/T Oil Temperature	Engine	221	638	700	A + B/256 - 40
+B Voltage	Combination Meter	221	021	7C0	A/10
Fuel Input	Combination Meter	221	022	7C0	???
Sub Fuel	Combination Meter	221	023	7C0	???
Fuel Pressure (High)	Engine	221	F6D	700	???
Fuel Pressure (Low) / Fuel Pressure 2	Engine	221	F6D	700	???
Intake Manifold Absolute Pressure	Engine	221	F87	700	???
Low Fuel Pressure Sensor	Engine	221	0CD	700	???
ExDID_1BE1	Engine	221	BE1	700	???
ExDID_15F7	Engine	221	5F7	700	???
ExDID_1F07	Engine	221	F07	700	???

??? formulas are the tricky part

So this is not much yet, but at least I hope this is enough information for anyone of you to join into this reverse engineering party.

CSV file that can be imported into Torque app for the custom PIDs can be found here: https://github.com/2m/gry-obd-pids

Hi dvim,
i see your post and try to give my knowledge to help in the effort of translating PIDs. I'm translating also some others and doing other interesting things
Regarding the response received on 7D8 after querying 7D0 (usually 8 byte more then querying addr: Sent [7D0] Rcv (7D0+8)[7D8], the reply is in a standard format when receiving replies via OBD/CAN and it is made like this:
if you sent 7D0 2162 you receive a response made by 7D0+8; the total length of hex bytes received; the first hex byte sent + 40, the second hex byte sent and the rest of bytes are the value returned (the number of hex bytes of the values are: total length of hex bytes less the first 2).
Example:
Sent
HDR Mode Pid
7D0 21 62
Rcv
HDR Len Mode Pid Value
7D0+8 5 21+40 62 03 00 00
Final
HDR Len h1 h2 h3 h4 h5 (5 hex bytes so Len is 5)
7D8 5 61 62 03 00 00

The h1 and h2 made this way help to intercept the right reply from a request: you ask 21 so you must find 61 in h1 for access the right mode and then you test the h2 to get just what you want from pids. If you don't do this you could intercept wrong values.

Hope to made a sort of good explanation and if you already know this.. just ignore the post Let me know if i must tell more.
Ciaooo

 

[R-power]

Eddy, should be possible, if...
...you got a valid PID
...the ECU "understands" this PID
...you get the formula to extract the correct information for each sensor
...you know which OBD header has to be used
then it should be possible. Do you got a PID to test?

Bye for now Fred

dears,
wonderful topic

i had carista app beta
they implemented TPMS management
i have now in carista my 4 tpms sensors id and pressures

i have tried with other apps (torquepro, cascanner, obdlink) no chance now to find the value.....
here carista APP
may be useful to someone to finf the PID ?

 

[dvim]

they implemented TPMS management

Thanks for the hint. Indeed, Carista Beta now has support for TPMS in GR Yaris.

I have updated the first post with the PIDs and formulas for all four tire pressure sensors. To get the values from those PIDs, a multi-line "Diagnositics start command" needs to be used in Torque Pro. You need to use the latest beta version of the app for that to work (more context here).

@dvim
you are simply special
thx a lot

in a few weeks canchecked will arrive with a OBD+CAN diplay

https://www.facebook.com/canchecked...-a-toyota-gr-yaris-lets-see-how-far-we-can-get-for-now-we-got-/704616490199756/

or also


in their plans they have also temperature from tpms in addition to temp
do you think temperatre will be possible ??
i have read the tpms sensor on the wheel woth autec tool in a garage and it gives both pressure than temp and probabily transit them both.
so maybe the ecu read it somewhere but do not use it
what do you think about ?
thx a lot for you effort in these data !!!

 

[dvim]

Yup, if CANchecked can pull it, then so can other OBDII apps, we just need a PID for tire temperatures. I'll try asking CANchecked nicely, maybe they can help us.

[Duca]

Hi

They politely declined.

Hi dvim, i will try to help you in finding the values for tire temperatures.
Today i will do some search and give you feedback.
I will also give you here the right formula for tire pressure calculation starting from X (decimal value from hexadecimal) so it's a little bit different from multiplying it with 0.01373

In PSI:
X=(0,29*X)-14,5
In Bar:
X=(0,29*X)-14,5/14,504
In KWP:
X=(2*X)-100

Let me know if it is right for you.

Found!!! Now i'm working to have the right formula for converting HEX values

 

[dvim]

Founded!!! Now i'm working to have the right formula for converting HEX values

I took the tire pressure formula from Miata forums: https://forum.miata.net/vb/showpost.php?p=9636079&postcount=5

Try the temperature formula from there as well

 (A - 50)              # celcius
((A - 50) * 9/5) + 32  # fahrenheit

Motivated by completing my OBD2AA dashboard with transmission oil temperature, I tried formula from other Toyota vehicle forums. "M/T Oil Temperature" sensor returns correct values with the "A + B/256 - 40" formula. I have updated the table in the first post. Here is how my OBD2AA dashboard looks now:

Is this gearbox temperature or rear clutchpack temperature? I've tried some settings on OBD fusion, with OBD mode 22 and PDI number 1638 and seem to be getting around 50 degrees with the car fully warmed up…does that make sense?

Thanks a lot for the magic done on here. This is phenomenal.

FWIU it's gearbox oil temperature.
