Life in the automotive industry used to be pretty predictable.
The vast majority of the work was mechanical… and when
diagnostics were needed, a cheap obd2 scanner the could give you basic live data and only do oil resets. Pretty much anything that wasn’t obvious by just looking and
listening to the car.
But, as I’m sure you’ve noticed, things have changed a bit.
Today, cars and trucks are less like machines and more like mobile super computers. And with each new model year comes new
features that require - you got it - new diagnostic capabilities.
