It;s not that the car would be displaying a code, a mechanic who has the scanner will connect it to the car socket and the scanner will tell a code..... the code then has to be seen in a book to determine the cause of the problem....... i have heard about this process on a baleno... as in my chevy exclusive there is no code stuff... the scanner displays the problem in normal english.......
U might need to take the car to an authorized suzuki workshop.....
