Been getting slammed at the shop this week. Had a 2019 Chevy Silverado towed in yesterday with a completely dead dash and a no crank no start. The previous shop threw parts at it and gave up. My usual scanner was struggling to even communicate and kept timing out on the network scan.

The guy in the bay next to me tossed me his topdon one. "Try this" He said. The topology map pulled up instantly. You could clearly see the blind spot module dropping off the high speed CAN. Unplugged the connector and the truck fired right up.

Honestly surprised how fast that scan ran compared to my older setup. It saved me hours of back probing connectors. Thinking about upgrading my own setup now since these network issues are getting ridiculous. What are you guys running for your daily diag tablet.
