Description:

This diagnostic trouble code is generated when the control software detects that the supply voltage (ELX) of the control unit for range shifting is below 9 V. This can be caused by battery issues, wiring problems, or faults in the control unit.

Reaction:

When this error is detected, the transmission will go to neutral to prevent potential damage.

Recommendations:

Check Battery Voltage:

• Ensure that the battery is fully charged and functioning correctly.
• Replace the battery if it is unable to maintain a charge above 9 V.

Inspect Wiring and Connections:

• Check the wiring and connections between the battery and the control unit for range shifting.
• Repair or replace any damaged or corroded wires and connectors.

Control Unit Inspection:

• Test the control unit to ensure it is receiving the correct voltage.
• Replace the control unit if it is found to be faulty.

Consult Technical Support:

• If the issue persists, seek assistance from technical support or a qualified technician.

Monitor System:

• After addressing the issue, monitor the supply voltage to ensure it remains within the specified range.

Note:

Maintaining a healthy battery and ensuring clean, secure electrical connections are essential for preventing low voltage issues and ensuring the reliable operation of the control unit.
