2010 Honda Ridgeline Check Engine Light Reset

Resetting the check engine light on a 2010 Honda Ridgeline is sometimes possible after correcting a simple issue, but a reset alone doesn’t resolve the underlying problem. At Coggin Honda Saint Augustine our technicians first read the stored trouble codes with OEM-grade scanners, then diagnose the root cause. If a sensor, emission part, or software update is required we provide a clear, written estimate and explain how prompt, OEM repairs deliver both immediate savings and long-term protection for your Ridgeline’s engine and emissions systems. Dealer-performed resets maintain transparency — we log the repair history and warranty work so future service remains consistent. For warranty-related repairs, work must be completed at a certified dealership to preserve coverage. We also offer flexible service financing if you need to get repairs done now and pay over time. To avoid unnecessary resets that mask problems, schedule appointment with our service team and ask about current service specials.
