This diagnostic trouble code (DTC), SSU 522451.01, is triggered when the voltage at the signal line of channel 2 of the wheel angle sensor (WAS) falls below 0.25 volts for longer than 320 milliseconds. This indicates a low voltage condition, potentially due to an open circuit in channel 2 of the wheel angle sensor.

This diagnostic trouble code (DTC), SSU 522394.09, is generated when the information from the Terrain Compensation Module (TCM) integrated in the StarFire ITC receiver is not recognized on the CAN BUS after four attempts. This indicates a problem in the CAN BUS communication or loose connectors.

READ MORE

This diagnostic trouble code (DTC), SSU 522387.07, is triggered when, despite a steering movement being commanded, the SSU control unit fails to detect a signal from the wheel angle sensor (WAS) or receives a signal that is too low. This indicates a failure in detecting the expected steering movement.

READ MORE

This diagnostic trouble code (DTC), SSU 522273.01, is triggered when the steering control valve (Y49) receives a control signal from the SSU control unit that is below 15% of the system voltage. This indicates an undervoltage condition in the control signal.
