Description:

This diagnostic trouble code is generated when the control software detects that the oil pressure at the forward clutch exceeds 12 bar (1200 kPa; 174 psi) and the slip exceeds 5% for more than 3 seconds.

Reaction:

When this error is detected, the control software may limit or disable the transmission functions, particularly affecting the forward clutch 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 Clutch Assembly:

• Inspect the forward clutch assembly for any signs of wear or damage.
• Repair or replace any faulty components in the clutch assembly.

Check Control Unit:

• Ensure that the control unit is functioning correctly and processing the pressure and slip signals properly.
• Reprogram or update the control unit software if necessary.

Consult Technical Support:

• If the issue persists, seek assistance from technical support or a qualified technician for further diagnosis and repair.

Monitor System:

• After repairs, monitor the oil pressure and slip levels at the forward clutch to ensure they remain within the specified range.

Note:

Regular inspection and maintenance of the oil circuit and clutch assembly can help prevent pressure and slip issues and ensure reliable operation.
