Description:

This diagnostic trouble code is generated when the control software detects that the voltage at the positive lead of the voltage supply for 5-volt components is above 5.25 V, indicating a short circuit.

Reaction:

When this error is detected, the control software may limit or disable the transmission functions.

Recommendations:

Inspect Voltage Supply Circuit:

• Check the wiring and connections for any signs of short circuits, damage, or corrosion.
• Repair or replace any damaged components.

Test Voltage Regulator:

• Verify that the voltage regulator is functioning correctly and providing a stable 5-volt output.
• Replace the voltage regulator if it is found to be faulty.

Check Control Unit:

• Ensure that the control unit is not sending excessive voltage to the 5-volt components.
• 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 voltage levels to ensure they remain within the specified range.

Note:

Regular inspection and maintenance of the electrical system, including voltage regulators and supply circuits, can help prevent overvoltage issues and ensure reliable operation.
