| Hi root ginger if you go to the website you can download the manual in advance if you wish. It's very simple to use, plug in display codes. look them up in the tables, scanagain, then scroll down to clear function an press enter.
It's nice to have the tool so that you can reset the light as soon as possible, and not have to wait for the dealer to have an appointment, thereby ensuring that the airbag system is active. |
