Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gabaɗaya, wanda ke nufin ya shafi motocin OBD-II masu sanye da kaya (GMC, Chevrolet, Ford, Dodge, Chrysler, VW, Toyota, Honda, da sauransu). Kodayake gabaɗaya, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.
