Diagnostic tester detects mileage manipulation

Diagnostic tester detects mileage manipulation

It is not always easy to determine the actual mileage of a vehicle beyond doubt, for example when it comes to a used car valuation, a leasing repossession or an appraisal. This is because the speedometer reading of many vehicles can be changed with little technical effort. The number of unreported cases is high: experts assume that the speedometer reading of every third used car sold in Germany has been manipulated.

With a new function of the compact KTS 250 diagnostic tester from Bosch, car workshops or other experts can now read out all the odometer readings that are stored in the various control units in the vehicle. By comparing this with the mileage on the speedometer, it is possible to determine whether the mileage stored there is plausible or whether it deviates from the other values. This can have a direct impact on the residual value of the vehicle in a used car valuation, when a leased vehicle is taken back or when a motor vehicle expert prepares a value appraisal. Insurance companies can include this check in damage assessments.

The mileage of a car is usually not only stored in the speedometer of the instrument cluster in the dashboard, but is also stored in many electronic control units (ECUs) installed in the vehicle. The mileage can even be stored in the seat memory or in the control unit for the electronic parking assistant.

After the diagnostic tester has been connected to the vehicle via the OBD cable, the actual values of the ECUs and fault memories can be read out. The new “Read odometer readings” function of the KTS 250 now lists all odometer readings stored in the individual control units. The diagnostic log can then be printed out on a printer in the workshop network or sent as an e-mail attachment directly from the KTS 250.

The KTS 250 ECU diagnostic tester was developed for mobile use. Its intuitive Android-based user interface is characterised by a high level of user-friendliness. Equipped with Bosch’s Esitronic diagnostic software, the KTS 250 allows fast ECU diagnostics on almost all passenger cars on the market. After automatic vehicle identification via the vehicle identification number, all ECUs installed in the vehicle are displayed to the user.
