Description:

This diagnostic trouble code is generated when the oil pressure at the reverse brake exceeds 2 bar (200 kPa; 29 psi) even though no 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 not stuck or faulty.
• Replace the solenoid valve if it is found to be defective.

Check Oil Pressure Sensor:

• Verify that the oil pressure sensor is providing accurate readings.
• Replace the sensor 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.
