Not a chatbot.
A diagnostic partner.
Every answer is grounded in OEM documentation — installation manuals, wiring diagrams, fault code tables, charging charts. When it doesn't have the spec, it tells you. It never guesses.
Three steps. Start to close-out.
Step-by-step guidance from the moment you arrive. Prentis handles the guesswork and sweats the diagnosis. You handle the fix and take the credit.
