I am getting the Active Headlights Inoperable message. Is that a ballast replace?
When starting the car and the headlights go through their up, down and side to side check, my driver-side headlight doesn't move. It remains in-place. Is that a ballast replace or do I need to purchase an entire new headlight? Any help would be greatly appreciated.

You will need a scanner, not just a code reader, able to read all modules.

I meant to say....I think that can pull the codes. I will try this evening. On another note, do you know if I can replace with two halogen headlamps and it will not throw any codes?
