TSC 523973.03 – B110 Sensor for Cab Position, Voltage Too High

TSC 523973.03 (TSC )

Code: 523973.03

Shortcode:

Description:

This diagnostic trouble code, TSC 523973.03, is triggered when, during operation/calibration, the TSC (cab suspension) detects too high a voltage (more than 4.75 volts) at the signal output of the cab position sensor (B110) when the cab suspension is at its top position.

Reaction:

When this error occurs, the cab suspension may not operate correctly, leading to potential misalignment and operational issues.

Recommendations:

Inspect Cab Position Sensor:

  • Check Sensor Output:
    • Verify the signal output of the cab position sensor B110 to ensure it does not exceed 4.75 volts when the cab suspension is at its top position.
    • Recalibrate or replace the sensor if necessary.

Inspect Sensor Circuit:

  • Check for Circuit Issues:
    • Examine the wiring and connections of the cab position sensor for any signs of damage, loose connections, or corrosion.
    • Repair or replace any faulty components in the circuit.

Verify Calibration Process:

  • Ensure Correct Calibration Procedure:
    • Follow the manufacturer’s instructions for the calibration process.
    • Ensure all necessary conditions (engine speed, tractor stationary) are met during calibration.

Note:

Maintaining the correct voltage range for the cab position sensor is essential for accurate cab suspension operation. Regular inspections and maintenance of the sensor and its circuit are crucial to prevent operational issues.
