John Deere has overly strict security on the electrical components of its tractor which doesn’t allow the owner of a tractor to make simple repairs or upgrades without having a John Deere technician travel out and do it for them. Our team has been tasked with decoding the CAN bus messages passed between tractor components, with this knowledge future work on modifying the tractor’s electronic systems will be significantly easier. The project is through California Polytechnic State University’s Capstone I/II class and sponsored by iFixit.
