Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

When that light comes on, a code has been set in the computer. Our next move is to get that code read with a code reader or scan tool.

Most parts stores will read the code for you for free, then you can let me know what it is and we will go from there.

Thanks, Ron
