PTD 521239.04 – Reverse Brake Oil Pressure Too Low
PTD 521239.04 (PTD )
Code: 521239.04
Shortcode:
Description:
This diagnostic trouble code is generated when there is no oil pressure at the reverse brake even though an oil pressure was specified. This indicates a problem in the oil circuit of the reverse brake or a faulty proportional solenoid valve.
Reaction:
When this error is detected, the control software may limit or disable the transmission functions, particularly affecting the reverse brake operation.
Recommendations:
Inspect Oil Circuit:
- Check the oil circuit for blockages or leaks.
- Repair or replace any damaged components in the oil circuit.
Test Proportional Solenoid Valve:
- Perform a diagnostic test on the proportional solenoid valve to ensure it is functioning correctly.
- Replace the solenoid valve if it is found to be defective.
Check Oil Pump:
- Verify that the oil pump is operating correctly and providing sufficient pressure.
- Replace the oil pump if it is malfunctioning.
Consult Technical Support:
- If the problem persists, consult technical support or a qualified technician for further diagnosis and repair.
Monitor System:
- After performing repairs, monitor the oil pressure at the reverse brake to ensure it is within the specified range.
Note:
Regular maintenance and inspection of the oil circuit and solenoid valves can help prevent pressure issues and ensure reliable operation.
