tuf question
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. |

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. -- *Rehab is for quitters. Dave Plowman London SW To e-mail, change noise into sound. |

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. |

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. Chris 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! Jeff Strieble, WB8NHV (email addy not shown to deter spammers) Fairport Harbor, Ohio USA |

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'. -- *A nest isn't empty until all their stuff is out of the attic Dave Plowman London SW To e-mail, change noise into sound. |

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... -- *What was the best thing before sliced bread? Dave Plowman London SW To e-mail, change noise into sound. |

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.... Goldenshuttle Homer J Simpson wrote: "Goldenshuttle" wrote in message oups.com...
