Thank you for your quick response. Install with these commands:. Lines and paragraphs break automatically. The standard seems to be to supply the device with Microsoft Windows software drivers and some form of GUI program for the user to interact with the ELM device. Thank You very much for this post!!!

Scantool – OBDII Car Diagnostic Software for Linux

Setting MaxPacketSize 64 usb Apparently many of the less expensive ones are prirate clones of the ELM chip created in China, but they seem to work. I believe they stopped including it in their distributions after WinXP. Note the libftdi requires root permissions to run, which is one linyx its disadvantages. If you are old enough to remember the days of dial up modems you probably remember the Hayes AT command set that became the standard for configuring and controlling your modem.

Connecting to the bluetooth adapter Get into your car and turn the ignition key to “II” or whatever setting powers the car without starting the engine. But it tells me Buffer full.

AT commands have to work for sure. I have a DOS library which just supports physical rs COM ports I cobbled together but am not willing to put it in the public domain so you are on your own there.


Apparently this library works with usb and bluetooth serial emulation in Linux, but not in Windows so if you want to use either of these modes in Windows you have to buy a custom made executable. Try my online puzzle page with CalcudokuKiller Sudoku elm237 online Sudoku.

Note if you are running Xwin and have the Dolphin file manager available you can run it and look at the ‘places’ listing on the left of the screen, if you have a bluetooth hardware device installed you will see ‘Bluetooth’ listed as one of the available places, clicking on this icon searches for and lists devices to which you can connect.

This might be the reason but still I should at least see some lines before the buffer gets full.

The ELM datasheet says that in a normal state the baud rate is usually set to Bd Bd in sleep mode. The Scantool software will not connect and gives a notice. Any help is welcome, congratulations for your blog. This is probably why I never managed to get linuxx to work on my car.


Although I know some friendly garage mechanics I wondered what was involved in checking and clearing these codes myself. If anyone wants to try these as text mode DOS executables for rs devices email me, I’m happy to make them available.

It appears that ScanTool. Notify me when new comments are posted.

While running it with sudo would work, it violates the principle of least privilege: The implementation of commands is also often faulty or faked. I played with these a little but am not a python guru and never got them running. I managed this with the “ScanTool” program, downloaded from the ScanTool. If you select “read codes” now you will see the error codes along with explanations of what they mean the codes are standard, but sometimes manufacturers have non-standard meanings, so you may get more than one explanation for each code: If you’re looking to use one of the several iPad apps for connecting to your car, you may want to look into a Wifi OBD2 adapter instead.
