Once you have collected some readings, you can pull your uSD card out

and take a look at the data recorded. There should be a file on your uSD

card called “DATA.TXT”, and it should include information like the following:

Note: If you’re only recording blank readings for your GPS, as shown

above, make sure you have your GPS unit in an area with a good satellite

view.

Once you’ve verified data is being stored to the uSD card, you’re good to

go! You’ve successfully interfaced with your vehicle’s CAN-Bus and can

now start digging into diagnostic codes and building projects around your

engine’s data.

Resources and Going Further

Going Further

Once you’ve gotten the basic functionality of the CAN-Bus shield working,

you can start hacking your car and interfacing your own electronics to your

vehicle. Try checking out different PIDs on the CAN-Bus with your vehicle,

or see if you can interface the CAN-Bus to control LEDs, speakers, and

more!
