Hello Guys, "DERATE DEF BEEPING"
ISSUE: Beeping Noise will not stop - related to DEF -
** I filled Def to full - still the beeping continues and error still on dash.
The truck is a new ProStar 2019 - 5.000 miles on it - VIEW IMAGE BELOW
I have turned off truck 5 times already and over night - still beeping - non stop
QUESTION - How can I clear this code error or this to make it stop beeping?
Thanks in advance !!
