RADC-A044

Tesla alert code in the Radar Controller (RADC) module. A condition prevents successful CANRX (CAN message received) for the steering wheel angle message, relating to a checksum, a counter, or an out-of-bounds signal value. The steering wheel angle message sent from the driver assistance system (DAS) Electronic Control Unit (ECU) to the radar controller (RADC) ECU is not as expected / as required for the radar to be enabled. ECU Internal fault - Hardware Watchdog ECU Internal fault - ADC Conversion Timeout ECU Internal fault - Mode Control Entry Error Vehicle Dynamics Error - the vehicle dynamics signals are out of spec, MIA or SNA ECU Internal ADC Overvoltage - Indicates an over voltage condition for the following voltage rails 1V25, 3V3, 4V5, 5V. Set when the voltages for the respective rails are above threshold. Cleared when over voltages return to nominal. Sensor function will be impaired, radar functions will be unavailable ECU Internal fault - ECU Module Configuration Error Received Country Does Not Match Learned Parameter When the learned parameters meet the ones being sent to the radar on CAN.

RADC-A044 is an Alert in the Radar Controller system. It is generally safe to continue driving, but have it checked at your next scheduled service.
