Description:

This fault code reveals that the Cab Load Center (CLC) switched supply voltage has dropped below 12.5 V while the engine speed is over 1500 rpm. This condition may indicate issues such as a failing battery, inadequate charging, or heavy electrical load exceeding the charging system’s capacity.

Reaction:

The system may initiate a low-power mode or restrict certain operations to conserve power and protect the electrical system.

Recommendations:

• Inspect Battery and Charging System: Verify the health of the battery and the effectiveness of the charging system.
• Reduce Electrical Load: If possible, reduce non-essential electrical loads to alleviate strain on the charging system.
• Check for Electrical Short Circuits or Drains: Search for any potential sources of electrical shorts or parasitic drains that could be depleting the battery.
• Technical Consultation Recommended: Persistent issues should be addressed by consulting with John Deere technical support.

Note:

Low voltage levels can compromise the performance and reliability of electronic systems, making regular system checks and maintenance essential for operational stability.
