this question needs some strong electronics knowledge. Hope someone can
answer...
A guy bought a Toyota Lexus 300 , model 1995. The mileage reader is
digital, and showing that it moved only 55,000 miles. Later he found
out that the mileage was reduced, or reset to sell it at a good
price.....We know that these things happen, but how did they manipulate
a digital (not a mechanical) reader ???

Guess it depends where they keep that info. I'd guess in the car's
computer.

Easiest way: two years before you want to sell the car, Drive the car
to the dealer, then when nobody's watching, apply the HV power supply
from your underdash neons to the computer for a second. Now tell them
to replace the computer under warranty.

A little harder: go to a junkyard, find a Lexus with low mileage, buy
the computer.

A little harder yet: Buy the service manual for the car computer, see
if there's a setup option for setting the mileage.

A little harder yet: Open up the computer, disassemble the rom to
find out where they keep the mileage.

Use an oscillator to roll it over?

You don't have to look to far to find 'specialists' who can reset these
electronic devices. Any safeguards the factory builds in can soon be
overcome with the knowledge and determination.

I'm constantly amazed you guys in the US don't set any store on the
service history of a car. I keep all the receipts for work done on my car
- I have to for my accountant. But stick them all in a folder after he's
finished with them. The service book is kept too and the dealer stamps it
and records the mileage. In the UK once a car is over 3 years old, it has
an annual MOT - and the milage is recorded then. So keeping those is yet
another check on the mileage. With computerised records it's also possible
to get the history of the car from a dealer - if it's been serviced there.
Of course all these *could* be forged, but the effort wouldn't be worth it.

With the right 'diagostic tool' you can manipulate most of the info held in
the computer.

WHat made you think its been changed? The sticker in door saying
oil was changed at 175,000 miles and its due back at 178,000?

When i worked at used car dealer back a few lifetimes ago, i watched
the "flipper" come in at night a turn a few clean cars into low mileage
cream puffs.

Those darn computers and databases are making flipping odometers kinda
pointless. Every time you take the car to an oil-change place or the
dealer they log the mileage into their computer. Worse yet are those
cars with looong warranty periods or free maintenance where the dealer
keeps track of the mileage. It looks mighty suspicious when a car has
racked up 28,000 miles a year for the first few years of the warranty,
then shows up for sale afterwards with much less than the expected
miles.

When i worked at used car dealer back a few lifetimes ago, i watched
the "flipper" come in at night a turn a few clean cars into low mileage
cream puffs.


Soon cars will have Internet connections and the flipper can sit at
home and turn back speedometers in his pyjamas.

or they just buy the setup on ebay:
item # 130031160644 for example.

When buying a car, I normally look at the gear stick, steering wheel and
pedals, if they are all brand new I am suspicious, but otherwise, the signs
of wear are a kind of odometer.


Hi...

Also the ashtray, wear around the radio controls, glove box release,
driver's side carpeting... there's lots

Take care.

Better to pay the $100 and get a good mechanic to check it for you.

I do that too, after I find a car that looks like it's probably ok. Finding
a good mechanic isn't always easy.

Back in the '70s when rolling back odometers (mechanical dashboard
counter types at the base of the speedometer dial) was popular, there
was a joke as to how to set them back. Since mechanical odometers would
run backwards when the car was in reverse (no kidding, I've actually
seen it happen), the joke went something like this: To set your car's
odometer back without fiddling with the cable and an electric drill (or
a couple of other dodges also used to set back old-style odometers),
just drive your car backwards through the Smoky Mountains one time.


I don't know, however, if this dodge would work with modern digital
odometers, as I'm not sure if they will run backwards when the car is
driven in reverse. If it does work this way, that could be the
explanation for why the car under discussion in this thread had
thousands fewer miles on it than the buyer thought it had--the previous
owner probably drove it backwards down a mountain or some crazy thing
like that. If not, then I just don't know, unless, as was mentioned
here, someone somehow got into the mileage computer and hacked it. One
way I can think of to set a car's digital odometer to zero, however, is
to disconnect the car battery for a day or two or run it down. I cannot
imagine for the life of me how the odometer would retain a previous
reading under those circumstances, unless the things have lithium
backup batteries or something like that; even at that, lithium
batteries still fail after a certain length of time, so the odometer
would lose its mileage memory eventually anyway. I have a digital
wris****ch I bought some seven years ago; the battery is still good, so
I think these cells should last just as long in a digital odometer
application. But the question still remains: Who keeps cars seven years
or more these days? The odometer backup battery will probably be dead
as a doornail by the time a seven-year-old (plus) car is sold, so I
would almost expect that the odometer would be reading zero anyhow.
Talk about a good way to fool a used-car buyer!

Instead of driving backward, just jack up the rear end, put chocks behind
the front wheels, and leave the car running in reverse for a few hours.
It was simpler and quicker to disconnect the speedo cable and use a drill
motor.

I don't know whether car instruments use it, but flash memory is cheap and
retains data without power.

Given reverse gear is usually the lowest of the lot - apart from in some
autos - you'd have to leave it running for quite some time to make any
appreciable difference, and is likely to cost you more in fuel than you
gain in any added 'value'.

Some rough figures from a UK car guide.

I've taken a Lexus GS300 1996 as the closest to the OP's I can find data
for.

For each 10,000 miles below average, it gains very roughly 450 gbp. It's
best mpg is given as 36 mpg (UK gallons) So even if cruised gently for
that 10,000 miles it will have used a minimum of 280 gallons. At a cost of
roughly 1300 gbp.

Now drive it in reverse for 10,000 miles - and assuming it doesn't blow up
as is very likely through overheating, you could at least treble the fuel
consumption. So to increase the value of your car by 450 gbp it's cost you
some 4000 gbp...

Homer, U misunderstood, I wouldn t hurt a fly even if I could. I only
advised the (mew mew) not 2 throw words coz some people respond with a
fist...not me anyhow.....and I prefer 2 use U instead of you....its
faster....
Now about clocking-back digital ODO..here is the deal.....All digital
readers are basically frquency meters, with some memory chip. This chip
can be identified, then find its data sheet, pulse the reset pin, but
you will get it ZERO reading...means you can not clock itback 2 certain
reading, only Zero...Brand new car !!! SOme manufacturers play smart by
hidng the chip model with black paint.., just scratch the paint
away...those idiots....use a plastic scratching tool not asteel one...

other method is to check what pulse is adding reading..if it is a
positive TTL (+5 volt) then feed the opposite (-5 volt) pulse and this
may start to reduce the reading till U clock to any reading U want..but
U need a signal generator, and tracer....a software on a laptop can
peform both.......

Happy clocking guys....
