This diagnostic trouble code (DTC), SSU 523822.02, is triggered when the Steering System Control Unit (SSU) detects that the wheel angle sensor-flow meter direction is incorrect after the manual steering portion of the SSU calibration procedure. This indicates a misalignment or incorrect configuration of the sensor and flow meter.

This diagnostic trouble code (DTC), SSU 523795.11, is triggered when the Steering System Control Unit (SSU) detects that the electro-hydraulic steering valve’s left and right deadband values differ significantly during calibration (greater than 4 counts difference). This indicates an inconsistency in the valve’s operation.
