I have been looking for an answer to this and have come up empty handed. Hours and hours of searching.
So basically if you have some old error codes stored in the abs and software to access it? Do NOT clear the old codes. For some reason it causes a C1998. Learned this the hard way.
It means you have to calibrate the ABS module. I'm using forscan and can log and manually change many many things but i'm very leery of running the "as built" ABS module calibration.
I even went to motorcraftservice.com, enter my VIN, and get the .AB file for my vehicle. Cool feature if you didn't know about it. It's gray area though and i'm not coming up with any answers as to whether i can load this. i do not want to cause any further issues. Ford dealer knew exactly what had happened, it's an inherent flaw in the system he said. Told me it would take 10 minutes or and it's very cheap to reflash it, 90 bucks. That's what i'll likely do but i was wondering if anyone else has Forscan and has ran the ABS as-built module flash.
Having C1998 causes the traction light to flash constantly and after about 1 minute of driving the check advanctrac message will pop up. No abs problems or anything, just those two annoying things. No other error codes after plenty of mixed driving yesterday, just C1998
The code can not be cleared without calibration/loading file.
Thanks for any help or opinions
