What does RADC-A054 mean?
Tesla alert code in the Radar Controller (RADC) module. The radar is blocked. This alert is primarily informational for radar blockage detection and pertains to the first frame of sensor blockage parameters. ECU Internal fault - Software Executed Unreached Code ECU Internal fault - SPI Fault Rx/Tx Received Radar Location Does Not Match Learned Parameter ECU internal fault - NVM Failure, replace sensor ECU Internal Under Temperature - The Radar internal NTC has detected below than normal temperature When the radar internal temp exceeds the lower temperature threshold. Radar functions will be disabled due to low operating temperature Radar Never Aligned - The radar has never been aligned Always set on new radars by default.
