hey guys chrisfix here today I'm going
to show you how to diagnose an airbag
light, so what should happen is when you
go to start your car, your airbag light
will come on and stay on for about like
three to five seconds then it will shut
off that means that your airbag system
is working fine but what happens when
they go to start your car and your
airbag light stays on or flashes well
this means that there's a problem with
your airbag system the flashes are
actually giving you a code this is a
2001 Mazda V 3000, it'll work for the
Ford Ranger the Mazda b-series, Ford
Explorer, and many other makes and models
but what it does is it flashes so one
two three four pause one two three four
five six so that's code number four six,
or forty six after you read your codes
it'll flash about five times it'll give
you five chances to read the codes your
airbag light will stay on and that'll
let you know that there's a problem, on
some cars there's no flashing it just
the airbag light comes on and then you
can just take it to Pep Boys or autozone
or any of those parts stores and they'll
check it for free so code number forty
six means that the driver side seatbelt
pretensioners circuit is broken
and the common cause for that is when
you move your seat or you put stuff
underneath your seat see this wire here
I'm going to go upside down you can see
that there's this connector right here
and what happens is moisture gets in
here or the connector gets loose , a lot
of times when you have something under
your seat or when you move the seat
forwards and backwards this will trigger
this it is a service bulletin for Ford
but they haven't had a recall for it so
all you have to do is take this apart
and spray some wd-40 in it so to get it
apart all you have to do is push this
clip down on the end and pull this right
out just like so and you're going to
spray a little bit of wd-40 in here or
use some dielectric grease that'll help
out just a little bit gets rid of
corrosion
and then I'm going to just take this and
plug it back in make sure it clicks make
sure this is together completely now
move your seat back and now we're going
to go start the car again and we'll see
if that light comes back on good the
lights off so that's how you fix it that
code was number four six or forty six
that was a driver side seatbelt
pretensioners circuit 47 is the
passenger side so do the same thing for
the passenger side there's also other
codes I'm not going to go through all
the codes but to give you an idea code
one 919 that's usually after your car
gets into an accident or if you had an
accident in the airbags deployed it's
the restraint control module memory and
it's full so you just have to replace
that RCM and that's the only way to fix
that there's code number forty-two and
that's the front impact sensor be
careful when you're working with the
airbags you always want to shut the car
off you want to disconnect the battery
for at least 10 minutes be super careful
because if you touch that front airbag
sensor and it goes off your airbag could
go off and that's definitely not good
the other thing that I'm going to
mention is number 27 that's another
common one and what happens is the light
bulb for this on/off switch for your
airbag goes bad it's called the PID
switch assembly and there's a light bulb
that you could buy from RadioShack for
only a few bucks and the part number
I'll put in the description but it's
number 272 - 334 and you could just
solder in a new light instead of paying
two hundred bucks for a whole new system
