Diagnosing No Communication / No codes w/John Forro

There’s nothing more frustrating than having a vehicle where there are no codes and no communication when you plug in your scan tool and try to communicate with a module. In this webinar, we will be discussing various tips and techniques one can do to help determine if this is caused by something as simple as a blown fuse or if its something more involved like a possible CAN network concern. If found to be a network issue, we will discuss some common sensed techniques on how one should approach the diagnostic routine to get the network back online.
