- the appropriate hardware and software. As described in Section 4.2.1, a certain hardware can be used to access the CAN bus of the vehicle, and consequently, other components. In particular, following the description in Section 3.1, it is possible to access the instrument cluster ECU, and thus its EEPROM where the odometer value is stored and the ABS/TCS ECU. For instance, once the tamperer has got access to the instrument cluster’s EEPROM, he can modify specific memory areas storing the odometer · wiki.unece.org
