OBDII Scanner Sketch

Developer Projects
#1

It was suggested to me that it might be kind of cool to have a sketch that can interrogate a car over the OBDII port to determine which ECUs respond and what sort of info each one might be able to provide.

Such a sketch is found here: https://github.com/collin80/OBD2Scan

You will need to have already set things up to compile for the M2 and then you need these libraries:



Now, if you get all that set up (be sure to get fresh copies. I just changed due_can) you should be able to compile and try it out on any car you want. It automatically determines baud rate so as long as the car has some traffic it’ll pick the proper speed. Thereafter you get output like this: (just a snippet below)

I’ve removed the last 5 digits of my VIN because I’m not sure whether it’s a good idea to post the entire thing all over the internet. Anyway, you can see that it found the VIN number of my vehicle and two ECUs. The first one supports all sorts of queries. The second one really doesn’t offer up much over standard OBDII. You can figure out which PIDs my vehicle supports by going here: https://en.wikipedia.org/wiki/OBD-II_PIDs#Mode_01

For instance, the first 8 bits were 10111111.
1 = Supports monitor state since DTCs cleared
0 = Does not support Freeze DTC
1 = Supports Fuel System Status
1 = Supports Calculated Engine Load
1 = Supports Engine Coolant Temperature
1 = Supports Short Term Fuel Trim - Bank 1
1 = Supports Long Term Fuel Trim - Bank 1
1 = Supports Short Term Fuel Trim - Bank 2

That is, read it all left to right. There are 32 bits per line so the left most is the lowest#, the right most is the highest number. This is kind of backward of how binary really works but it helps for human readability. Just keep it in mind because it’s not a standard bit ordering.

There is a LOT that could be done with this. I didn’t bother putting any of the actual PID codes in there. Someone could fill out all 160 if they felt like they had the time. Also, there’s many other things that one could ask the car for. I’m up for accepting pull requests.

Hi CollinK, I just set all up and it works all nice!`

I do have some time and as I think that’s a useful thing i could add the codes you mention.
As I’m new to all the Car Ecu and Macchina things I ask you to shortly point me to where the codes should be added to the program?

regards

#3

If you look here: https://github.com/collin80/OBD2Scan/blob/master/obd2_codes.h

You’ll see that I did kind of start things for PID. But, I didn’t create any textual descriptions for them. Something like this might work:

char* PID_DESC [] = 
{
   "SupportedPIDs1",
   "Monitor Status Since DTC Clear",
   "Freeze DTC",
   "Fuel System Status"
};

Except, there would be about 160 strings there instead of 4. With those strings it’d then be possible to go through the list of PIDs that are returned as supported to turn them into the text description instead of just a bit field.

#4

I added the 135 PID descriptions in Mode #1 from the Wiki. By now the printout is ugly and the queries are in reverse direction to the bit code. I may invest some more time to clean up. Plus i think that it may be useful to make it log to the SD card to make it easier to use so you can get a log without carrying a PC with you.

Hi folks,

as mentioned I added logging to SD card so you can plug the M2 to a car without carrying a notebook with you. The sketch generated a file named “log” with the supported PID numbers and descriptions.
At the moment it replaces the file every time you plug in and additional info like the ECU name and so on is not in the file.

Would be nice if anybody could test it as it looks like my Renault doesn’t support many IDs.

#6

I complied the sketch and uploaded it successfully. I tried it out on my Honda Accord 2013 but it couldn’t determine the baud rate like Savvy Can. I think tonight I’m going to try to manually set the baud rate anyone else have this problem?

#7

SavvyCAN has a auto detect routine built in. If it is guessing wrong you can type in a new baudrate in the configuration screen. MOST CANBUS ports are 500k baud but you could run into one that is 250k or 1000k baud.

Personally I would try connecting a standard ODBII dongle with software that tells you what the baud rate is and go that route if you can’t seem to get it working with the M2. Then you can manually set the baud rate. In newer vehicles as mentioned elsewhere there is nothing at the ODBII port unless you poll for it. To get around that you may have to tie into a databus within your car that is active.

#8

I just did a scan of a 2014 Toyota Rav 4 using this branch of the code:

https://github.com/sergiomiracco/OBD2Scan/tree/dev

Here is what I get in the serial terminal (VIN obfuscated), pretty cool :grinning: I had to plug M2 in the car, press RESET button and then open the terminal right away to catch everything.

Nice work guys! A couple ideas that come to mind:

  • Some sort of visual feedback indicating we are scanning and writing to SD card. Maybe blinking Red when “recording” and Green when done? or something like that

  • Increment file name so it doesn’t overwrite. It would be cool to be able to plug this into several cars, download the info to M2 and have 1 file for each car.

Keep it up guys, this is great stuff!

M2 cannot use SD card
#9

Maybe a log file by vin number would be a good way so you can keep different car files in there and be able to track them too.

#10

The log file is now put into a folder which increments with every new scan. I chose to organize in folders so you can split up the files by VIN numbers if you like without loosing scope of the whole scan.

#11

Savvycan was able to detect the baud rate with no problem and I was able to see traffic. This sketch can’t seem to detect it I still have yet to try to manually set the rate.

#12

What is the reason for only using 7 of the 8 available mailboxes?

  for (int filter = 0; filter < 3; filter++) {
      Can0.setRXFilter(filter, 0, 0, true);
      Can1.setRXFilter(filter, 0, 0, true);
  }  
  //standard
  for (int filter = 3; filter < 7; filter++) {
      Can0.setRXFilter(filter, 0, 0, false);
      Can1.setRXFilter(filter, 0, 0, false);
   }

I use this and it doesn’t seem to cause me any problems:

  // Declare 4 standard and 4 extended mailboxes for each controller
  for (i = 0 ;  i < 4;  i++) {         // standard (0..3)
    Can0.setRXFilter(i, 0, 0, false);  // Mailbox#, MID, MAM, extended
    Can1.setRXFilter(i, 0, 0, false);
  }
  for ( ;  i < CANMB_NUMBER;  i++) {   // extended (4..7)
    Can0.setRXFilter(i, 0, 0, true);
    Can1.setRXFilter(i, 0, 0, true);
  }
#13

The reason is: whoops.

Hi Collin

Can you help me out here…?
I have tried to use Macchina M2 and your interface Savycan. It worked on our 2012 Ampera the first time, bot not on my 2001 Peugeot 406 coupe 3.0 that i want to convert to Leaf motor. First i would like to have a solid CAN database so that i can simulate motor running to use all the gizmos in the car.

So when i connect M2 to 406c OBDII socket nothing happens. No LED nothing. Whilst on Ampera everything starts flashing and i can observe a lot of traffic even when the car is off. Is it possible that on Peugeot OBD port has different speed than usual?

Also i noticed something odd with M2. Usually when i connect M2 to USB and laptop i get “Arduino due hardware on com15” or similar. However sometimes i connect the same, but hardware says something like “bossac port on com16”. When i connect Savycan i cant start communication. I have to unplug M2 and play with drivers to get Arduino Due back.

What is your experience with CAN/OBDII, could the pins be switched on OBDII connector? Why would they do such a thing?

A

#15

Verify that your Peugeot actually uses CANBUS. It is very likely that it does not. CANBUS was not required in the US until 2008. Some GM vehicles included CANBUS earlier but not as early as 2001. I wouldn’t be surprised if your 2001 uses a different protocol.

#16

Well shoot! It does use a similar protocol, but it is not CAN, it is ISO 14230-4. However ELM bluetooth reader instantly starts to work, when i connect it.
So is there hope for me or not?
How should i try to hack the Pug then?

EDIT: I saw something… KWP2000 is also compatible on ISO 11898 (Controller Area Network) supporting higher data rates of up to 1 Mbit/s.

and

Very common protocol for 2003+ vehicles using ISO9141 K-Line. Uses pin 7.
Two variants of ISO14230-4 exist. They differ only in method of communication initialization. All use 10400 bits per second.
ISO 14230-4 KWP (5 baud init,10.4 Kbaud)
ISO 14230-4 KWP (fast init,10.4 Kbaud)

So maybe it will work if i change speed to 1Mbps and/or 10,4Kbaud rate.
Collin does Savycan work with pin 7 of the OBD and K/Lin bus?
A

#17

Please be aware that there are very few utilities at this time that can deal with anything other than canbus for reverse engineering. The M2RET sofrtware does not currently support anything other than CANBUS or SWCAN and SavvyCAN currently only works with CANBUS and SWCAN…

There is a LIN library if you go to the macchina documentation and look up the “spotlight” projects. At this time you have to roll your own tools to capture and process.

I hope to change this though my summer project but I can not promise anything at this time. I hope to add full Lawicel 2.0 support and allow modular development for M2 so things just work but at this time this is not the case. (With full Lawicel 2.0 support Craig Smith has promised to add support into Metasploit which should be beneficial. If I learn how to do Wireshark protocols I MAY add the protocols to Wireshark as well…)

Lawicel Basically is the basis for CAN driver support in Linux. With proposed Lawicel 2.0, driver level support can be added into Linux to be used as simply as SocketCAN.

I will be announcing my summer project in 2 weeks after I finish this semester. I am still looking at my resources at this time and need to focus my time on my finals between now and the 24th.

#18

Rod’s basically right here, I never supported anything other than CAN (and swCAN) in SavvyCAN. In theory support could be added for some of the other protocols and bus types but those things don’t interest me so I haven’t done it.

Though, LAWICEL 2.0 is already in M2RET. In fact, I helped define how it would work. So, in actuality the reference code for LAWICEL 2.0 is M2RET as I believe it’s the only thing that actually supports it currently. The problem is that there’s nothing to talk to it. I think that’ll change this year. Yes, the goal is to standardize how all the various bus types are presented so that a single code base could feasibly read/write to many bus types without needing to know which it is talking to. Work on all that is quite preliminary at this point. And, like I said, I couldn’t care less about k-line and all the other old crap so that sort of makes it fall into someone else’s lap. :wink:

#20

I’m just beginning in this and I don’t have a programmer’s background (pardon my stupid questions).

I’m trying the OBDII Scanner sketch on my M2 on 4 different cars (Subaru BRZ 2013, Mazda 3 2013, Dodge Grand Caravan 2005, Kia Sportage 2013) and it always fails with similar results (only difference is Mazda 3 CAN1 baud is 125000 instead of 250000).

I must be missing something obvious but I don’t get it. Can anybody help ? Thx.

Here are the results as read from the SD card (same thing in serial console, just more verbose…)
