I purchased a 2004 EB 5.4 a few weeks ago and recently the traction light is blinking constantly and CHECK ADVTRAC appears on the screen. Is there anything i can do for this the ABS has a code of C1998 when i use my scan tool.

Thanks for that info, i wasn't able to do that. I now have another problem with it. If I start driving down the road, about 1/4 mile down it says ADVTRAC OFF then CHECK ADVTRAC. and will stay that way until i restart the vehicle. However, if i drive in reverse for a short distance, it will say ADVTRAC ON?? Is it possibly a wheel speed sensor?

It could be, but unless you have access to a Ford VCM diagnostic scanner, this sounds like a problem that you will have to fix at the dealer. Alternatively you could get a chinese Ford VCM for about 200 bucks, but you could end up messing things up if you don't know what you're doing, since it's able to write to the PCM. Standard OBD scanners are generally safe to use by anyone since they're only able to read.

I'm dealing with the same issue... I used a snapon solus ultra scanner and pulled up the C1998 code.... Of course dealer here wants 110 to do their scan even after i tell them what code i got
Update, so i'm still having issues. over the past few of cold mornings i have had it act like i am sliding and it starts hitting the brakes by itself and slowing me down. after a few seconds of this i get ADVTRAC OFF CHECK ADVTRAC. When i pull codes i get C1277 and C1278. i know that is for the steering angle sensor, but does anybody have any ideas?
So I fixed this by replacing the part attached to the steering column. Not the sensor itself, but the plastic wheel. It was only a 17 dollar part. If anybody needs assistance with this feel free to contact me.
