Description:

This diagnostic trouble code, TSC 523951.02, is triggered when the TSC (front-wheel drive axle with TLS) perceives motion in the wrong direction during calibration or bleeding. This can indicate that the plugs are mixed up at the solenoid valves, there is a problem in the raising/lowering solenoid valve circuit (TLS), the pressure buildup/reduction circuit (TLS), or there is a problem in the hydraulic circuit of the TLS front-wheel drive axle.

Reaction:

When this error occurs, the front axle calibration or bleeding process fails, potentially leading to incorrect alignment and operational issues.

Recommendations:

Check Solenoid Valve Connections:

• Verify Correct Connections:
  • Ensure that the plugs for the solenoid valves are correctly connected.
  • Correct any mixed-up connections.

Inspect Solenoid Valve Circuit:

• Check for Circuit Issues:
  • Examine the wiring for any signs of issues in the raising/lowering or pressure buildup/reduction circuits.
  • Repair any identified issues in the circuit.

Inspect Hydraulic Circuit:

• Check for Hydraulic Problems:
  • Inspect the hydraulic circuit for any signs of blockages, leaks, or other issues.
  • Repair any identified problems in the hydraulic circuit.

Note:

Proper calibration and bleeding of the TLS front-wheel drive axle are essential for accurate alignment and smooth operation. Regular inspections and maintenance of the solenoid valves and hydraulic circuit are necessary to prevent calibration faults.
