Inconsistent long term RAM data.
شرح
A portion of the internal RAM is used to store configuration data. At system start, information is read from a non-volatile memory. The information from the non-volatile memory is stored in the portion of RAM used for configuration data. After this initial store, the configuration data should be available for reading only. No change of the information is permitted. The consistency of the data is controlled with a checksum. If the checksum test fails, this DTC is set. If the checksum test is successful, this DTC is set inactive.
علت
• Exposure to extensive electro-magnetic radiation • Software flaws • ECU hardware error.
