BMW & Rolls-Royce EDR Data Overview
This section provides general information about the EDR capability of this ACM and the type of EDR data that may be recorded. Always refer to the Data Limitations section of the CDR report for further information about the ACM and limitations of the data retrieved. The information included in the CDR report's Data Limitations section for this ACM is considered to be more precise and current than the generalized information included below. The actual data retrieved from the ACM may differ from what is described below. Review all vehicle coverage notes which are referenced in the Supported Vehicle list for this ACM before attempting to retrieve data from it.

The list below includes data elements which may be supported by the EDR in the vehicle:
• SYSTEM STATUS AT RETRIEVAL
