Doing research on this and have seen some of your videos on it. Let's say I'm looking at a vehicle that I want to make sure there isn't flood damage. Setting aside the obvious things you have pointed out, is there a risk of hooking up an obd2 scanner to a suspected flooded car and it causing a short? Should you never hook up an obd2 scanner to a possibly flooded car? Cause if it were to short or cause an issue, the owner would make you responsible for the damage? Is there such a thing?
Did you try the search box? I know there are at least a couple of topics covering this already.
It wasn't necessarily a question of how to spot flood damage, as I said I'd watched his other videos. Searching, I came across "Is it worth it to repair my 2014 Toyota Yaris minor flood damage"
I see talk about hooking up an OBD2 scanner for a flood car in that post, but my question specifically is "is there risk of causing more damage to the electronics using an OBD2 scanner on a flood damaged car."
No.
If there's nothing wrong with the scanner, then will not add any problems that weren't already there.
