Re: Breaking the code

One byte, so that is 8 bits...
Hmm
738 inches of mercury = 362.43 psi
That sounds a lot like the high side of the a/c to me, but I don't know much about them. That would also be affected by the...

Re: Breaking the code

In a sense, all of those numbers are nodes on a binary search tree that each load their own pointer to a memory location. These pointers are located on a data table nearby.

In C++ it would look...

Re: Breaking the code

Data is always in the wild, it is just a matter of how far you are willing to go to get it. Just like that designer worm you mentioned ;)

Re: Breaking the code

I've always found it quiet interesting <.< Especially the new lightweight firmwares for bluetooth/RFID/WiFi honeypotting. Always wanted to crack one of those custom hacktools open

Re: Breaking the code

Looking at the code in that area, there is a function I say starts at that address <.< I can't really tell if it is bad code or not.
Doubtless it looks different when paged over though <.<

Re: Breaking the code

Ok... If my tracing is correct the actual memory address for PID 1154 is at B73B

The first number is a ENUM listing, as the code checks for 11, 12, 13, and few other oddballs, and loads a physical...

Sorry for the delay guys, had to clean house a bit. Literally <.<
House, car (prolly about 40lbs lighter now), bad relationships go poof, etc etc

Ok, I set a data structure for the formatted...

Re: Breaking the code

Hmmm, should be no math, and be in kPa <.< The base system is metric if I remember right. I think OldNuc can confirm on that.

That still doesn't sound like it is it though, was worth a shot,...

Re: Breaking the code

So the real PID for Tranny Temp is $1154

The cmp I was seeing before, was doing a sanity check on the packet.

Hmmm, can you try sending $119D for BARO in kPa?
I doubt it is the right, but...

Re: Breaking the code

Packet should look like this being sent:
6C 10 F1 22 xx yy 01

PCM_ID = 10
TOOL_ID = F1 (I need to find the memory location of this)

Mode 22 replies are formed in memory location 383 and can...

Re: Breaking the code

Mode 22 == Request_Diag_Data_by_PID 8D

Ok, something you may want to try is to keep pinging "memory" locations, with the y byte set to 01

I'm looking at the code, and it pulls from the buffer,...

Re: Breaking the code

Is 62C (143.6F) possible for tranny temp?

The problem with you sending that, is that it is the "encrypted" address.
5401, 15401, 4510, 14510, A208, 1A208, and D401 are all sections of code.
But,...

There is a lot of data access to that area, but for some reason, I don't think that is it <.<

I'm currently working under the suspicion that MODE+PID = RAM address for that byte of data

Been contemplating it... I'm currently on an Ubuntu liveCD for recovering my data.

Re: Breaking the code

Yeah, apparently a new *feature* of windows7 is for all the services to panic at boot if the log files are corrupt. Pretty much just a matter of forcing a rebuild.

For reference http://en.wikipedia.org/wiki/OBD-II_PIDs
And I know it is wikipedia, but I don't have access to the SAE papers yet.
