PTP 524228.11 – Park Sump Block Valve Fault

PTP 524228.11 (PTP )

Code: 524228.11

Shortcode:

Description:

This error code is set when the shift lever is returned to park, the sump block solenoid is commanded ON, and the PTP checks that the park brake circuit can hold pressure. If the park brake circuit fails to hold pressure during this self-check, the code is triggered. This issue may be caused by a faulty park sump block solenoid or leaking park brake piston seals.

Reaction:

The control unit limits functionality to prevent potential damage.

Recommendations:

  • Inspect Park Sump Block Solenoid:
    Check the park sump block solenoid for proper operation. Replace if it is faulty.
  • Check for Leaks:
    Inspect the park brake piston seals for any signs of leaks. Replace seals if necessary.
  • Verify Pressure Holding:
    Ensure the park brake circuit can hold pressure during the self-check. Use diagnostic tools to measure pressure.
  • Check Wiring and Connections:
    Inspect wiring and connectors related to the park sump block solenoid for damage or corrosion. Repair or replace as necessary.
  • Consult Technical Support:
    If the issue persists, consult technical support or the manufacturer for further assistance.

Note:

Maintaining proper pressure in the park brake circuit is essential for safe vehicle operation. Regular inspections and maintenance can help prevent related issues.
