I plugged this into the truck to read and actually hoped it would say no issues as the truck had recently been serviced. It does read exactly that. I am very pleased, it is big enough to read, and small enough to be handheld. It is versatile for any vehicle to get a diagnostic reading on. It will be a great tool for me as a woman to know what I am looking at before I go to the service station to have repairs done in the future. A must have for any vehicle owner to do it yourself repairs or know what you can expect for a shop repair bill.
