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 high, indicating a short 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 short circuits, damage, or corrosion.
• Repair or replace any damaged wires or connectors.

Test Solenoid Valve:

• Perform a diagnostic test on the proportional solenoid valve to ensure it is not shorted or faulty.
• Replace the solenoid valve if it is found to be defective.

Check Control Unit:

• Verify that the control unit is operating correctly and not sending excessive current to the solenoid valve.
• Reprogram or update the control unit software if necessary.

Consult Technical Support:

• If the problem persists, seek assistance from 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 short circuit issues and ensure reliable operation.
