Description:

This diagnostic trouble code is generated when there is no oil pressure at the forward clutch even though an oil pressure was specified. This indicates a problem in the oil circuit of the forward clutch 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 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 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 forward clutch 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.
