Depends on what you want to do, and what type it is.
If you've changed wheel size or gearing, and wants the odo to measure correctly, you need to have it calibrated. If it's a mechanical unit, this means that you'll have to change a tiny cogwheel somewhere to one with another tooth count. If it's an electronic odo, you need to use a gadget called a pulse divider, which is quite tricky.
If it's an electronic one, and you've replaced the instrument cluster, and/or the odo, and want the new one to display properly, an authorized dealer workshop should be able to reprogram it for you.
If it's a mechanical one it'll basically have to be disassembled and reassembled to matche the old number, although really old versions can be manipulated by spinning the odo cable with an electric drill.
If you're looking to remove a few miles to get a better price when selling the car - well, that's illegal.
If the bcm stores the odometer mileage, you need to get one that has the correct mileage in it.
It is the mileage that is actually on the car. If the odometer is replaced, the correct reading is written down. Add that to the reading of the replacment odometer and you have the actual mileage on the car.
It is highly unlikely that a digital odometer would show a one in front of the correct mileage. It sounds like someone is trying to sell you a car and tell you it has less mileage than it really does.
There is not an odometer cable. The odometer is driven by the speedometer. If the odometer is not working then you will have to replace the speedometer head.
where can i get free odometer readings?
If the speedometer works but the odometer does not, the odometer has failed.
You cannot reset the odometer in your car, however you can reset your trip odometer.
You can only restart the trip odometer. There usually is a button on the instrument cluster that brings up the trip odometer or the regular odometer. Once you have the trip odometer showing just hold down that button for a few seconds and it will reset the trip odometer back to zero.
Well both of those are from sensors in the wheels so maybe make sure you are using the correct wheels.
Because your odometer, or something connecting the odometer to the battery, is broken. Most likely the odometer is the problem if the rest of your dashboard is working fine.
There is no odometer/speedometer cable in that vehicle. The odometer/speedometer is electronic.
My speedometer works and the odometer does not because there is a plastic gear in the odometer that is broken.
