[s-cars] Engine stopping problem -- Starting Issue

[thomas.pollock at AMD.com]

Any electrical engineers out there ?  6 years ago is a long time.  I don't
want to start a panic but all electrical components have a life span. The
flash parts that hold the software in our ECUs definitely have been spec'd
for how long they will hold up before transistors break down etc. Oh, and
the more you reprogram them the quicker they start to break down. I don't
have a data sheet in front of me but I wouldn't be surprised if they are
spec'd for "maybe" ten years or so. That wouldn't mean that in ten years we
all suddenly start failing but...

Now depending what kind of application a certain part is being designed for
(military versus commercial etc) and how much room is left in the flash part
to put "extra" code in, you can do all kinds of things to check and in some
cases repair circuitry that is on the way out. I'm not at all familiar with
the software side either so who knows...  Anyone ?

tom.

Yes, the ECU has been modified 6 years ago. And in fact, ECU was taken
out few months ago to read the program (to be send to MTM for checking
some idle speed parameters). Maybe I should check that ECU connectors
are fine.

Thanks,
