TSC 523975.03 – TLS Axle All the Way Down, Voltage Too High (During Calibration)

TSC 523975.03 (TSC )

Code: 523975.03

Shortcode:

Description:

This diagnostic trouble code, TSC 523975.03, is triggered when, during calibration or bleeding, the TSC (TLS front-wheel drive axle) detects too high a voltage (more than 1.5 volts) at the signal output of the TLS position sensor (B53) when the TLS front-wheel drive axle is at its bottom position.

Reaction:

When this error occurs, the TLS system calibration process may fail, leading to incorrect positioning and operational issues.

Recommendations:

Inspect TLS Position Sensor:

  • Check Sensor Output:
    • Verify the signal output of the TLS position sensor B53 to ensure it is within the expected range when the TLS axle is at its bottom position.
    • Recalibrate or replace the sensor if necessary.

Inspect Sensor Circuit:

  • Check for Circuit Issues:
    • Examine the wiring and connections of the TLS 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:

Proper calibration of the TLS front-wheel drive axle is essential for accurate positioning and smooth operation. Regular inspections and maintenance of the TLS position sensor and its circuit are necessary to prevent calibration faults.
