hi Jim. i just bought an 02 diesel superduty, and it has the parking aid
system . is there a way to test the system without buying a WDS 418-F224
diagnostic tool as described in the service CD??
the unit is constant on like there is something behind the vehicles, and i
am suspecting a bad sensor.
when i unplug one of the sensors, it does not work, so i am assuming that
the sensors are wired in a series circuit.
short of buying a new sensor and swapping out the sensors one at a time to
find the bad one, is there any way a D.I.Y'r can diagnose the system??
also, it does not have a trailer brake controller in it. am i correct in
assuming the 4 wires on the driver side under the dash at the fuse box are
the wires used to connect the brake controller??
Hi, Tom.... first thing I have to ask is if there is a hitch in the receiver
on the truck..... If so, try removing it first... Not all hitches will
trigger the PAM beeper, but it does seem to happen depending on how they may
be set up.... Also, make sure the sensors are clean and free of debris (even
having the tailgate down can trigger them). If those don't give you a
solution, a "real" scan tool will be able to poll the Park Aid Module and
retrieve a sensor specific code - All of the ones I see, a failed sensor
will turn the PAM <OFF> automatically...... I don't feel the concern is
going to be a sensor, but, without the scan tool, your substitution method
may be all that's left (unless there are two or more sensors involved - yes
it would be a strange coincidence... but I ain't seen everything there is to
see yet, either).
I'm going to assume that the wires you are referring to are the red, white,
blue and black blunt cut wires? These four should be the "customer access"
wires and the other ends of them should be right near the take-out to the
underhood lamp at the firewall. With the knee bolster panel removed. look to
the passenger side of the opening and there should be a six pin connector (I
recall that the hardshell will be grey). This will be a plug in for the
brake controller.... New, there would have been a corresponding connector in
a bag in the cubbyhole.... occasionally, one might strike paydirt even on a
truck a few years old...
ok, thank you sir. as usual, you are spot on. the pintle hitch was in there,
but it still goes constant with it removed.
and yes, i was referring to the r-w-b-bl. blunt cut wires.
no connector in the cubbyhole though. this was a landscapers personal truck.
while it was taken care of very well, it has 150k miles on it in 5 years,
and there are allot of nickel and dime things missing on it. all the big
dollar items were done to it by the local dealer already. front end
completely redone, batteries, alternator, tires, brakes,and trans all within
6k miles, so i felt it was a good deal at $12k, and i am doing all the
little stuff so it will last forever like my 88 diesel.
top postingly yours, ;-)
You gotta stop that top posting shit... it's much more fun to furble past
lines and lines of shit I should have read in previous posts and get to the
bottom to find some dumbass has decided to say "Me too"....
Anyway... the plug for the trailer brake controller should only be a few
bucks from the dealer (or you could simply hard wire it in... everything you
need for the brakes will be at that one connector).
The PAM sensors can have a pretty wide angle... so make sure there isn't
anything they can "think" is an obstruction in the way (these alarms
regularly sound when backing off my four post hoist) and be sure there isn't
any crap on the sensors....
I'll go out on a limb and suggest biting the bullet for a code scan for the
park aid system.... as I'd mentioned, all of the "bad" sensors I have
encountered have turned the system <OFF>.... Anyway.... you've got mail....
ok is this better?? :-)
i already ordered the plug from the local dealer.
and i am gonna try cleaning everything and resetting the sensors and bezels.
if that don't work, i will then take it in to the service dept.
the service writer owes me one anyway.
