Obd2 Scan Tool Software Open Source

Automotive diagnostics have come a long way since the “idiot lights” of the 1980s. The current version of the on-board diagnostics (OBD) protocol provides real time data as well as fault diagnostics, thanks to the numerous sensors connected to the data network in the modern vehicle.

While the hardware interface is fairly standardized now, manufacturers use one of several different standards to encode the data. [Alex Sidorenko] has built an which provides a serial interface using the and supports all OBD-II standards. The hardware is built around the LPC1517 Cortex-M3 microprocessor and can accept a couple of different versions. Here’s the, and a set of Gerber files () for the PCB layout, if you’d like to dig in to it’s internals. The is used to provide bi-directional half-duplex communication interface with the micro-controller.

Also included is the that provides an interface between the micro controller and the physical two-wire CAN lines on the ODB-II connector. The serial output from the adapter board is connected to a computer using a serial to USB adapter. The is written in C++ for the LPCXpresso IDE – a GNU tool chain for ARM Cortex-M processors, but can also be compiled using a couple of other toolchains. He’s got instructions if you’d like to build the, or if you’d like to. Download Ws_Ftp 12 Rapidshare. We featured [Alex]’s way back in 2007, so he’s been working on this for a while and has a good grip on what he’s doing. Posted in,, Tagged,,,,,,,,,,,,,, Post navigation.

ABS is not covered under the compulsory information that vehicle manufacturers have to provide by law so the answer to that is no. It has been an uphill struggle with manufacturers to force them to release the engine diagnostics and real time data information and, for now, that is where it stops. An open source OBD will allow people that are brave enough to extract more and hopefully that will all be collected somewhere so that eventually there will be something equivalent to the X431 Launch that does a reasonable job on most cars. Nad Pathfinder Uniform Patch Placement here. A perfect job on all cars is about as likely as viable cold fusion.

Ford has the OpenXC platform ( ) for reading stuff, but it also is really limited. The point being that you could put the codes from any vehicle on the reader, but even the Ford data is limited. I happen to have couple of Chipkits with the network (includes 2 CAN interfaces) shield, so i was thinking of trying it, but since it’s for Fords only currently (no other car manufacturer or anyone else have contributed any codes) and i don’t have a Ford, it’s kind of useless to me. I do wish it would take off. I second what @Alan Hightower says. The next rev should have the ability to repurpose any pin that isn’t 4, 5 and 16 (grounds and +VE) to any method of communication.
