So I think the easiest thing to do would be to get a 9 volt battery connector like this: and some alligator clips with wires: and just plug in the battery, connect the clips to the 9v connector wires and to the ends of the car's battery connectors then disconnect the the car battery and install the new one. You could probably get it all for a few ...

Depends on what you would like to do with it. If you just want to clear some generic codes and the check engine light, then most generic OBD2 cables should work with appropriate software. If you want to do more advanced things, like reading Volvo specific codes or changing available parameters then what you need is VIDA + DiCE. It's a Volvo diagnostics tool ...

From what I can tell, the 05 uses CAN protocal, not OBD2, and then there are some issues with using a generic tool, and most accepted, if not only official method, is to use a volvo-specific (proprietary) scan tool to read the codes. Look over the link below and it appears that there has been some headway made in adapting a 'generic' scan tool to work, but ...

It looks like the only option other than an aftermarket system would be to goto a Toyota dealer or a independent shop with the Toyota TechStream Software and to enable this feature. It looks like this option should be on by default but was never setup or was disabled for some reason. Edit: It looks you may be able to do this from the Multi-Display. SET ...

You cannot easily "tap" into any ECU/PCM. Depending on what year your vehicle is, it could be a simple set of analog gauges which you could tap into the signal line, but you'll need to do some hardware design to convert the signals to usable data. If it's a newer vehicle, you'll have to deal with the canbus protocol and that will be very difficult. Your ...

If your car has a OBD2/ODBII port then it is achievable. I'd imaging the simplest way would be to use a ELM327 type cable or even a bluetooth adapter to provide the interface between the pi and the car.

To affirm Max's answer, yes this shouldn't be too difficult. Here's a great link to get you started http://www.cowfishstudios.com/blog/obd-pi-raspberry-pi-displaying-car-diagnostics-obd-ii-data-on-an-aftermarket-head-unit Very cool project, it'll be interesting to see how it turns out for you.

OBD II only guarantees communication and specific PID availability with the engine computer. For effect I repeat, ONLY the engine computer. The passenger seat belt indicator would be either part of the body control system or the restraint/airbag system. These are manufacturer specific and will change depending on the make, model and year of the car. ...

It looks like it's a J2534 device. These support reflashing with the proper software. I've used the OpenPort 2.0 another J2534 device with the TechStream software before I assume this is the same just made in China. Generic OBD2 cables don't support reflashing as they're missing the necessary chip.
