Description:

This diagnostic trouble code, TSC 523973.31, is triggered when the TSC (TLS front-wheel drive axle) fails to reach its level position within 60 seconds while traveling at speeds above 10 km/h (6 mph).

Reaction:

When this error occurs, the cab suspension may not level correctly, potentially leading to operational issues and discomfort.

Recommendations:

Inspect Cab Suspension System:

• Check for Obstructions:
  • Ensure there are no physical obstructions preventing the cab suspension from reaching its level position.
  • Remove any identified obstructions.

Inspect Hydraulic System:

• Check Hydraulic Pressure:
  • Verify that the hydraulic system is providing adequate pressure to achieve the level position.
  • Repair any leaks or blockages in the hydraulic circuit.

Inspect Sensors:

• Check Sensor Functionality:
  • Verify the correct operation of the TLS position sensor (B53) and oil pressure sensor (B167).
  • Replace any faulty sensors.

Verify System Calibration:

• Ensure Proper Calibration:
  • Follow the manufacturer’s instructions to recalibrate the cab suspension system.
  • Ensure all necessary conditions are met during calibration.

Note:

Maintaining the proper function of the cab suspension system is crucial for vehicle stability and comfort. Regular inspections and maintenance of the hydraulic system and sensors are essential to prevent operational issues.
