At Park Place Lexus Grapevine our technicians explain why a proper reset follows a full diagnostic and any necessary repairs. We use Lexus OEM diagnostic equipment to read pending and permanent codes, verify repairs, and then confirm that systems return to proper function before clearing codes. This transparent approach protects your engine, emissions systems, and long-term vehicle value. Customers benefit from factory-trained technicians, OEM parts, and warranty-backed repairs; if an issue is covered, repairs must be completed by a certified dealership to maintain coverage.
