Vauxhall (Opel GM) DPF PID
on: June 2, 2013 (GMT)

Hi, I’m currently suffering from persistent diesel particulate filter problems with my Zafira 1.9cdti 150 (08 plate). Unfortunately the built in PID do not cover the specific sensors I wish to monitor. Can anyone advise the PID for the following sensors: DPF saturation, DPF temp, DPF differential pressure, etc. I am not too bothered about the exact details for the formula’s (although this would be nice). I would like to basically monitor if and when a regen cycle is occurring, indicated by a rise in DPF temp and the state / saturation of the DPF indicated by rise and fall of DPF differential pressure. Any help would be most appreciated.

This would be an amazing addition

This would be excellent. Who do we talk to someone we can get these made up?

You might try testing 017A pid
for a possible response.

((B*256)+C)*0.00145038 ?
((D*256)+E)*0.00145038 ?

Wiki suggests this maybe related
to DPF ?

EGTs with 0178 as of Torque Pro 1.8.89
if your vehicle supports it.

Edit:

Torque Pro includes a DPF Pressure pid
which uses 017A.

I see the requests in the scanner
AA0105
AA0117
AA0118

Hi, I’m trying to do the same (my first post here).

I want to share with you what I’ve been able to discover so far, and need your help to make Torque work with it.

the PID is aa0118.
I can get the right response with ELM327 terminal with:

at cra5e8
at caf1
aa0118

response is
823
0: 32 34 00 5B 00

while if I add “at h1” I get:

5E8 18 23 32 34 00 5B 00

The meaning is:
23 *2 = DPF status (%). in this case was 70%
5B *5 = km since last regeneration
00 (last byte I get) = Regn. in progress (%)
The “32” seems to always stay unchanged, while the “34” is slighting increasing over the time.

usually regeneration starts when DPF status is above 80%

Unfortunately I’m not able to use Torque to get those values. I tried adding “atcra5e8” in the “diagnostic start command” and “atcra7e8” in the “stop command”, but the equation considers the second useful byte (5B in my example” as the “A” byte.

How can I get the interesting bytes in torque?
It seems Torque ignores the first bytes.

that you have given addresses raise doubts
make the terminal requests that I gave

Now a more less understandable
where you got the information about the address 5e8
if your address is correct reception 5e8, the response structure is not standard and Torc be able to decrypt it vryat
make the terminal
atz
ath1
atsp6
atsh7e0
atcra5e8
20
3e
aa0118

Isn’t mode AA part of dynamic pids?

I’m not sure Torque will accept modes
other than typically 01, 21, 22 and 23
for pids?

but as always I could be wrong.

Hi!

It’ll accept them in the test part of the editor, however AA won’t be optimised and it’s likely not going to be recognised by the core of the app.

However, I can fix that as you’ve provided me with some useful ELM stuff in your posts above. I’ll get this sorted for you in the next update with a bit of luck!

(I was also a bit skeptical about the ‘AA’ address having not seen anything like that before, but as you’ve shown it working, I’ll stick support for ‘AA’ pids in the app! it’ll be in 1.8.92 or 1.8.93)

It would be great!
I’ll do the latest test suggested by cintakc later on.

Meanwhile I can provide some results I get from Torque:
PID: aa0118
Equation: A*5
OBD Header: Blank
Diagnostic start: atcra5e8
Diagnostic stop: atcra7e8

Pressing “test”:
Result for equation: 315.0
Command: aa0118
Response: 822
0:325D003F00

So Torque considers “A” the byte containing “3F”, while the first useful byte is “22”, in the first row of the response, so basically 4 bytes before.
With this configuration the connection with ECU is anyway not perfect, as it sometimes disconnects, sometimes says there are errors (it was perfect using standard pids only).

I tried using atcra5e8 in the profile custom configuration, but then torque looses the connection.
In the diagnostic start command, instead, I can use only one command. If I try with more than one (separating with \n) I get no response.

Start and stop diagnostic commands (in the PID editor) now will accept multiline commands in the next update

ie: ati\nat@1\natrv (you get the general idea – ‘\n’ is the separator between commands just like in the ‘custom init’ part of the app)

3E01 is handled in the ‘start diagnostic’ command box and is repeated periodically.

10xx should also work, though this command does not need to be repeated, so it’s a one-shot affair which torque should handle.

You’ll get these new abilities in the next udpate

(also tidied up the ‘testing pid’ window a bit and fixed a couple of bugs there too)

Definitely doesn’t follow the J2190 spec(hence why I was skeptical previously) – the replies ought to be EA to an AA request (like 62 is a reply to mode 22)

This creates a little bit of a headache as you can imagine.

Vincent, could you send me a debug file?

In the general settings, click ‘enable debugging’ (near the bottom of the screen) then restart the app

Then start the app, go to the ‘realtime information’ screen (with the PID you’re trying to setup showing). Let it show for about 20 seconds, then press menu, “send debugging information”

Put your forum name in the box that pops up(so I can locate the debug) – I’ll have a look at the debug and see if I can work something out to add support for that AA mode

Debug file sent.
