This was recommended to me when I first started out years ago and it’s been some of the best advice I’ve gotten as a mechanic. The new OTOFIX D1 Max2 I got reminded me of this so I decided to make this video.
I think the best way to diagnose things is to know how they work when they’re working. The best way to know how something is broken is to observe it when it’s working. I think this provides a baseline that can be used to be more efficient at figuring out what’s wrong when a vehicle sets a fault code, or when just about anything is broken.
I hope this information is helpful.
