How Does Free Check Engine Light Testing at United Nissan Work?

If your check engine light is on, and there are no obvious signs that may lead to a breakdown, it may be safe to drive short distances. To ensure we're prepared for your arrival, it's preferred to make an appointment, though it is not necessary.

Once you arrive at our service department, a technician will hook your car up to an OBD-II code reader and scan the diagnostic codes. These codes are run through a database of over 26 million verified fixes, and our technicians are happy to explain them and help you find a repair solution.
