Mene ne wannan yake nufi?
Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi motocin OBD-II sanye da kayan masarufi (Dodge, Ram, Ford, GMC, Chevrolet, VW, Toyota, da sauransu). Kodayake gabaɗaya, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.
