Single 2 second Beep about every 10 seconds
2010 Ford F150 XLT 2WD- I
purchased it May 12, 2017 from a
dealer. Today it started making a
single 2 second beep about every
10 seconds and the pattern
continues whether the ignition is
off and on. Airbag light comes on
when initially turned on and goes
off with the other dash lights. I
haven't checked the battery. Don't
know how old it is. They said they
replaced it and did oil change but I
don't know.
