Structured checks
0/3 checkedWork through observations, not guesses
Does the engine crank or does the hybrid system reach READY?
Crank/READY behavior is a useful observation for narrowing the next diagnostic step.
Is a warning light or message shown?
The exact warning text/code can be more useful than guessing from the no-start symptom alone.
These checks organize observations and safety decisions. They are not a substitute for manufacturer service procedures or a qualified diagnosis, and CarFactBook does not assign a failed part without supporting evidence.
