There's a bloke (a real bloke)
named Graeme Fletcher that does road testing
for a TV program called Motoring 200X,
or right now it's Motoring 2006
and the Sports Channel remembers to feature
it from time to time, usually on a Saturday
morning.
Now Graeme's a pretty good road
tester. Restricted as he is by the fact that
he, like all other RTs, has to toe the line on what
he says about some manufacturers
car or other, he's pretty outspoken. But
he has one bee in his bonnet that bugs me to death.
He's highly vocal about the necessity
of every car being equipped with ABS
brakes.
Like most journalists, technically
qualified or not, he insists that this
automotive feature is a necessity - even on a
car costing
less than a good home entertainment
system these days.
And I keep saying that most ABS
systems don't do a very good job of actually
stopping you in the worst of conditions and are
phenomenally expensive to
repair. In fact, I have a whole raft of clients
that ask me to disable their ABS system in winter
time
and a whole lot more where the
system has already failed and they definitely
don't want it repaired.
To take a recent example of the
cost of these devices, let's look at a strange
set of symptoms that popped up this week at
our shop.
A Ford Contour arrived that was
putting its own brakes on and causing
the car to skid, almost out of control, at about
90 Km/h.
A road test with an analyser attached,
showed that the wheel sensors all agreed
that the car was travelling at 90 Km/h, but the
computer control module was reading
70 km/h and was assuming that the wheels
were spinning, as they would be if you
accelerated hard on sheer ice.
This caused the traction control
feature of the ABS system to apply the brakes
quite heartily and to continue to brake vigorously
because the speed differential,
betwen the computer and the wheels was
continuous and proportional.
This weird electronic gremlin didn't
happen every time, but if the ABS light came
on, you KNEW it was about to brake all by itself
- hard!
OK, so now we jut have to replace
the control module, right?
Think again - a call to the dealer
established that this particular black
box costs C$ 5,400!!
No I didn't just add a zero by mistake
- C$ 5,400!!
This is about twice the value of
the car, so guess what?
We have another driver out there
somehow managing to stay out of trouble on
his new snow tires,
just the way he did before ABS
was invented.
Usually, ABS, when optioned, adds
about $ 400 to the cost of a new car. Air
conditioning is usually a $1000 option.
The value of these systems however,
when bought as individual components over
a dealers counter, will usually
quadruple in "value".
The more stuff you have, the more
stuff you have to go wrong.
And the more stuff they're going
to go on trying to sell to you.
