It happens that a car enthusiast faces a difficult task: it is necessary to reset the speedometer. There are many reasons for this. Corrective measures require equipment, the readings of which began to diverge from reality. Most likely there was a failure. Only professionals can tweak the mileage on their own, therefore, if you want to reset the mileage or reduce it, then contact a specialized institution.
Instructions
Step 1
There is an opinion that the speedometer is reset to zero only to hide the real data on the mileage that your car hit. However, there are situations in which a mileage adjustment is simply necessary. The odometer readings are corrected. And they resort to this in the case of, for example, replacing the engine or replacing the odometer. If an odometer with zero mileage is installed, then, accordingly, in order to bring the numbers to reality, it should be twisted up. And if you take a used odometer with more mileage than you had, then it needs to be adjusted downward.
Step 2
Mechanical odometers will not be of interest to you now, refer to the technology of twisting electronic speedometers. Specialized centers have at their disposal an arsenal of available tools. To reset the speedometer readings, a programmer, adapter, scanner and other cunning devices are used. The complexity of the work lies in the fact that it is necessary not only to change the mileage in the on-board computer, but also to get rid of information in the memory of the microprocessor. It can be located anywhere in the vehicle and contains, as already mentioned, information about the mileage, as well as the frequency of service inspections.
Step 3
Reprogramming is used to reset the speedometer, and only good equipment does not harm the smooth operation of the rest of the panel's instruments. Today, specialized centers practice the use of several technologies for zeroing speedometers. One of them is reprogramming via connectors. This method is used if there is a memory encoding and an access protocol. An alternative method is the introduction of a new microcircuit, thanks to which it will be possible to adjust the mileage as much as necessary. And one more technology: twisting the odometer by receiving signals from an external generator. Here, the masters will have to go into detail about decrypting the data.
