Description:

This error code is caused by the park brake pressure sensor circuit being open or short to ground. When this code is present, the PTI control unit assumes a pressure of 2100 kPa (21 bar) (305 psi) when the park is released. Park brake pressure can be viewed at PTI Address 023.

Reaction:

The control unit limits the functionality of the equipment to prevent potential damage.

Recommendations:

• Inspect Sensor Circuit:
  • Check the park brake pressure sensor circuit for any open connections or shorts to ground.
  • Repair or replace any damaged wiring or connectors.
• Test Sensor Voltage:
  • Verify that the voltage levels in the sensor circuit are within the specified range.
  • Replace the pressure sensor if it is found to be faulty.
• Evaluate Ground Connections:
  • Ensure all ground connections are secure and free of corrosion.

Note:

Maintaining proper voltage levels in the sensor circuit is essential for accurate pressure readings and reliable operation.
