Description:

This error code, RPM 000168.04, is generated when the supply voltage (BAT) falls below 9 volts. This can occur due to issues with the battery, wiring, or charging system.

Reaction:

When this error is detected, the control software may experience limited or no functionality, leading to potential engine starting issues or electrical component failures.

Recommendations:

• Inspect Battery:
  • Check the battery voltage and condition. Ensure it is properly charged and replace the battery if it is failing to hold a charge.
• Verify Wiring and Connections:
  • Inspect the wiring and connections between the battery and the control module. Look for any signs of damage, loose connections, or corrosion. Repair or replace any compromised wiring.
• Check Charging System:
  • Ensure the alternator and charging system are functioning correctly. Test the alternator output and replace it if it is not maintaining proper voltage levels.
• Inspect Ground Connections:
  • Verify that all ground connections are secure and free of corrosion. Clean and tighten any loose ground connections.
• Consult Technical Support:
  • If the error persists, consult John Deere technical support or a certified technician for further assistance in diagnosing and resolving the issue.

Note:

Maintaining a stable supply voltage is crucial for the proper operation of the control software and electrical components. Regular inspection and maintenance of the battery and charging system are essential to prevent such issues.
