1. A system that facilitates protecting vehicle event data from overwrite, comprising:

  • an electronic control unit (ECU) having a processor that records event data related to vehicle operation;

    a memory that stores the event data; and

    an electronic tool that communicates with the ECU and comprises a data locking module that sends a data lock signal to the ECU to lock the stored event data as locked data such that the stored event data cannot be overwritten;

    wherein the ECU, in response to the data lock signal, stores the event data as locked data in a dedicated portion of the memory to preserve the event data for subsequent review.
