2015 Lexus GX 460 Check Engine Light Reset

Resetting the check engine light on a 2015 Lexus GX 460 may seem straightforward, but a simple reset without proper diagnostics can mask recurring faults and risk further damage.

Our technicians use Lexus-approved equipment to read and clear codes, then verify that the issue is resolved through test drives and readiness checks. Choosing a certified dealership ensures OEM-level transparency, documented repairs, and continued warranty protection—important benefits independent shops can’t always match. We also help customers understand any codes found, offer OEM parts, and provide written estimates that outline immediate and long-term savings from correct repairs.
