Description:

Error code CSC 523973.03 indicates that during the calibration or bleeding and calibration process, the voltage at the signal output of the cab suspension sensor is too high (above 4.75 volts) when the cab suspension is at its highest position. This typically points to a short to a high voltage source.

Reaction:

The calibration process is aborted to prevent incorrect calibration settings due to the high voltage reading.

Recommendations:

• Inspect Electrical Connections: Check the wiring and connections to the cab suspension sensor for signs of a short to a high voltage source. Repair any damaged or exposed wires.
• Measure Sensor Voltage: Use a voltmeter to measure the voltage at the cab suspension sensor to confirm it is within the acceptable range when the cab is at its highest position.
• Replace Defective Sensors: If the sensor is faulty and causing high voltage readings, replace it to ensure proper operation.
• Review and Update Software Settings: Ensure the control software settings are correctly configured to handle the sensor’s voltage requirements.
• Perform Functional and Calibration Tests: After repairs, reset the system and conduct functional tests and a full calibration of the cab suspension system to ensure accurate sensor data and proper calibration.

Note:

Maintaining proper voltage levels in the cab suspension sensor is essential for accurate calibration and smooth operation. Regular inspection and maintenance of sensor connections and voltage levels help prevent calibration issues and ensure system reliability.
