2010 Acura TL Check Engine Light Reset

Resetting the check engine light on a 2010 Acura TL is possible with an OBD-II scanner, but a reset without a proper repair is only a temporary fix.

Our service approach ensures accurate code reading, genuine parts, and factory-level procedures that protect against repeat failures. Choosing Nalley Acura often costs less overall than independent shops because we prevent costly follow-up repairs and extend vehicle life. For warranty work, repairs and resets must be completed at a certified dealership to preserve coverage and maintain a complete service record for resale value.
