With most accidents where airbags are deployed the module will also contain "crash data". Crash data cannot be cleared by MES, whereas all other errors, once fixed, can easily be Motor, mehanika i elektronika, sve je Fiat 500 (Biće malo predstavljanje u zasebnoj temi, samo da ga prvo osposobim ) Ono što od starta nije radilo su Blue&Me i USB port.
