That is also an option.
When testing something that generates a signal or a voltage like a CPS or a car battery
I try to start closest to the signal source when possible.
That way if the signal source tests good it is a wiring or connector problem.
If I start from the far end and don't get a signal I don't know if it is wiring or a connector or the signal source that is at fault until I do more testing.
