Description:

This diagnostic trouble code (DTC) is generated when the control software measures a voltage above 5.25 V at the positive voltage supply for 5-volt components. This indicates a short circuit to a positive lead.

Reaction:

Limited or no function of the transmission.

Recommendations:

Measure Supply Voltage:

• Use a multimeter to measure the voltage at the positive voltage supply for the 5-volt components.
• Ensure the voltage is within the expected range (4.75 V to 5.25 V). If it exceeds 5.25 V, further investigation is required.

Check for Short Circuits:

• Inspect the wiring and connectors for any signs of a short circuit to a positive lead.
• Repair or replace any damaged or shorted wiring and connectors.

Inspect 5-Volt Regulator:

• Verify the operation of the 5-volt voltage regulator. Replace it if it is faulty or providing excessive voltage.

Verify Component Integrity:

• Ensure that all 5-volt components are functioning correctly and are not causing shorts or drawing excessive current.
• Replace any faulty components.

Update Control Software:

• Ensure that the control software is up-to-date with the latest version from the manufacturer.

Consult Technical Support:

• If the issue persists, consult technical support for further diagnostic procedures or potential hardware issues.

Note:

Regular inspection and maintenance of the power supply system and related components can prevent issues related to high supply voltage. Ensuring all connections are secure and free from corrosion is crucial for reliable operation.
