Description:

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.

Reaction:

When this error is detected, the steering system may not respond accurately, leading to potential issues with vehicle control and safety.

Recommendations:

Inspect Steering Valve:

• Check the electro-hydraulic steering valve for proper operation.
• Ensure the valve is functioning consistently in both directions.

Perform Calibration:

• Recalibrate the steering system to ensure accurate deadband values for both left and right directions.
• Follow the manufacturer’s guidelines for the calibration process.

Update Software:

• Ensure that the SSU and related system software are up-to-date. Apply any available firmware updates to improve system performance and consistency.

Verify Sensor Signals:

• Ensure that the sensors providing feedback to the SSU are functioning properly and providing accurate data.
• Inspect the wiring and connectors related to these sensors for signs of damage, loose connections, or corrosion.

Replace Faulty Components:

• If the steering valve or related sensors are found to be defective, replace them with new, genuine parts.

Consult Technical Support:

• If the error persists after performing the above steps, consult technical support or the manufacturer for further assistance.

Note:

• Regular maintenance and inspection of the steering system components can help prevent deadband inconsistencies.
• Ensuring accurate calibration and proper sensor functionality is crucial for reliable steering performance.
