Description:

This diagnostic trouble code is generated when the voltage supply of 12-volt components in the transmission enable circuit is too low, indicating a short to ground or an internal fault of the control unit.

Reaction:

When this fault is detected, the tractor transmission cannot be shifted, and the 3rd gear is engaged automatically, resulting in limited transmission function.

Recommendations:

• Inspect Transmission Enable Circuit:
  • Check for any shorts to ground in the transmission enable circuit.
  • Repair or replace any faulty wiring or components.
• Verify Voltage Supply:
  • Use a multimeter to check the voltage supply to the 12-volt components.
  • Ensure that the voltage is within the acceptable range.
• Check Control Unit:
  • Inspect the control unit for any internal faults that might cause low voltage.
  • Replace the control unit if necessary.
• Inspect Connectors:
  • Ensure all connectors in the transmission enable circuit are secure and free from corrosion.
  • Clean or replace connectors as needed.

Note:

Regular inspection and maintenance of the transmission enable circuit can help prevent voltage issues and ensure reliable operation of the transmission system.
