2026 Ram 3500 Check Engine Light Reset

Resetting a check engine light on a 2026 Ram 3500 can be simple in some cases but risky if done without diagnosing the root cause.

At Herb Chambers Chrysler Dodge Jeep RAM FIAT of Millbury our approach begins with a factory-grade scan to capture stored trouble codes and freeze-frame data, letting technicians pinpoint whether a reset alone suffices or if repair is necessary.

Choosing our dealership means faster diagnostics, transparent estimates, and immediate documentation of work performed, which helps preserve resale value. We provide service financing if you prefer to split costs, and we frequently run service specials to lower your out-of-pocket expense. To protect your truck and warranty, schedule service with our factory-trained team in Millbury, MA.
