What is topology in OBD-II?
A topology scan in OBD2 is like getting a bird’s-eye view of all the car’s control modules and how they’re connected. It maps out everything, showing which modules are communicating and if there are any issues between them. It’s super handy because you can quickly spot problems, like a module that’s not responding or communication errors, without digging through each system manually. It’s a time-saver and makes troubleshooting way easier!
