PCM replacement?

Well it appears as though my car needs its PCM replaced. This is just
the start. With absolutely no warning at all, the computer dies??
They are quoting me $754 at a minimum, because they are not sure if
something else will be reported once they can actually get it hooked up
to the computer. GRRRR. Has anyone else has this problem? They can't
tell me why it happened either. Other than of course the warranty is
up and I just finished paying it off.

Computers these days seldom fail unless they are damaged by an improper
boost or charge. Who is "they"? This kind of problem is best left to a good
dealer or highly qualified shop with extensive diagnostic capability, for
sure no one on a newsgroup is going to be able to diagnose it. A lot of
money is wasted replacing perfectly good computers when the problem is
really in the wiring.

Re: PCM replacement?

The car is currently at a dealership in my town, however I don't really
trust them much. If the computer was not working, wouldn't they know
it right away, instead of taking 4 hours to diagnose? How do I know
that just the chip doesn't need replacement or something smaller than
the entire computer? I just have a feeling Ithat 'm being ripped off.
I keep searching Technical service bulletins that are out on the web,
but I don't see anything that pertains to the entire PCM going awry.
It just seems like a big repair for a 5 year old car..

Even if they have good diagnostic abilities, they aren't good at
communicating that with me. I asked them for detail repair quotes and
when I stopped by to pick it up, the service rep had written the price
on the back of his business card. He couldn't tell me why the computer
would break or why there wouldn't be any indication of problems..
wouldn't you guess there would be some kind of "log" on the computer
they could access?? I'm just mystified and annoyed that there isn't
more information available...

Sorry to be so whiney,
Megan

Or by test procedures improperly carried out...!

In the UK, a "cottage industry" has built up repairing failed ECU's. (That's
what we call "car computers"). Typically, the ECU is sent away (together
with its PATS key) to be repaired for a fixed price. This can be as little
as 1/3 of the price of a new ECU.

The usual failure is only of an output transistor or something equally
trivial, so the repaired unit is as good as new.

It might be worth investigating whether a local independent garage could do
this for you.

Re: PCM replacement?

Are you a member of some Automobile Association? They might help their
members with an advice on subjects like this. At least they do in The
netherlands.

Re: PCM replacement?

Just an update for anyone who cares...

So my focus has been at the dealership for over a week. I wouldn't
know a thing unless I called them everyday. They NEVER call me first.
I called everyday last week to check in on what was going on.. nothing
until Friday. Each day I called I was promised they would let me know
as soon as something came in (the PCM) for installation. I called
Friday afternoon and they had already installed the PCM and then went
ahead and ordered a diode because apparently I needed one too. So
fumed and pissed I waited all weekend to hear back today about when
they would finish with the diode and I could finally fork over fort
knox to them to get my car back (approx $1100 and counting). Lo and
behold, NO PHONE CALLS. I call the service manager to ask what is
going on, and get his voicemail. The service tech who has been
"dealing" with my case calls me back about an hour later and says that
guess what, I need a new alternator too. Might as well! Luckily (?) I
had the alternator replaced in Oct of 2004 so it was under warranty
(the part) but not the labor. They are thinking now (don't hold your
breath) that the alternator is the devil of it all and caused the
problem with the PCM and diode.. etc etc.

I am so annoyed with this dealership, I will get my car back which they
refuse to budge any price on (past warranty) and sell the thing as soon
as possible.

The 2000 Ford Focus is the devil.
