Answer:

An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical). The noun derives from ancients, from ("path" or "gateway") and ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth.

Answer:

An instrument for measuring the distance travelled by a wheeled vehicle.

Most odometers work by counting wheel rotations and assume that the distance traveled is the number of wheel rotations times the tire circumference, which is a standard tire diameter times pi (3.1416).

Almost every car now comes with a digital odometer. It is a common misconception though that digital odo units are much harder to tamper with. That might be the case some 10-15 years ago when the fraudsters and mechanics weren’t much into the tech know-how of the car. However, that’s not true anymore and digital odometers that are tampered with don’t even look out of place and leave no tell-tale signs of odometer tampering. This is because the whole process is mostly electronic. Any guy with decent know-how of car software and electronic system can perform this job.

To alter the readings on a digital odometer, the console of the car is removed and hooked up to a laptop (even smartphones now), and the desired mileage is flashed into the chip that controls the odometer. Replacing the chip and re-soldering them on the printed circuit board that has the odometer chip is also a pretty common practice. Smudgy glass with fingerprints behind the plastic, ill-fitting speedometer console or scrape marks from screwdrivers near the screws holding the instrument console etc are some of the most evident signs of tampering, but tough to figure out if the work is done by a professional.

Disconnecting the speedometer cable is also a widespread practice. This is mostly done by third-party dealers who buy a car from the original seller. They then drive the vehicle around without the speedometer connected until it’s sold to another customer.

HOPE IT HELPS YOU.
