Description:

Error code CSC 523973.15 occurs when, during calibration, the cab suspension position sensor’s voltage does not fall below 2 V when the cab is fully lowered. This indicates an incorrect sensor signal, leading to calibration failure.

Reaction:

• Calibration is aborted.
• Limited function of the vehicle.

Recommendations:

• Inspect Sensor and Connections: Examine the cab suspension sensor and its wiring for any signs of damage or loose connections. Repair or replace as necessary.
• Measure Sensor Voltage: Use a voltmeter to measure the voltage at the cab suspension sensor when the cab is fully lowered to ensure it falls below 2 V.
• Replace Faulty Sensors: If the sensor is faulty and does not provide correct signals, replace it.
• Recalibrate Sensor: Perform a recalibration of the cab suspension system to ensure accurate sensor readings and proper calibration.
• Review Control Software Settings: Ensure the control software is correctly configured to process the sensor signals during calibration.
• Conduct Comprehensive System Tests: After repairs, reset the system and perform thorough tests to confirm that the sensor operates correctly and the cab suspension calibrates successfully.

Note:

Accurate sensor signals are vital for the proper calibration and operation of the cab suspension system. Regular inspections and timely repairs help maintain the system’s reliability and performance.
