Description:

This diagnostic trouble code is generated when the control software detects that the current at the lead of the proportional solenoid valve for the forward clutch is too low, indicating an open circuit.

Reaction:

When this error is detected, the control software may limit or disable the transmission functions, particularly affecting the forward clutch operation.

Recommendations:

Inspect Wiring and Connections:

• Check the wiring and connections to the proportional solenoid valve for the forward clutch for any signs of damage, corrosion, or disconnection.
• Repair or replace any damaged wires or connectors.

Test 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 faulty.

Check Control Unit:

• Verify that the control unit is operating correctly and sending the proper signals to the solenoid valve.
• Reprogram or update the control unit software if necessary.

Consult Technical Support:

• If the problem persists, consult technical support or a qualified technician for further diagnosis and repair.

Monitor System:

• After repairs, monitor the transmission system to ensure proper operation and that the current levels are within the specified range.

Note:

Regular inspection and maintenance of the transmission wiring and solenoid valves can help prevent open circuit issues and ensure reliable operation.
