Description:

This error code indicates that the switched supply voltage in the Cab Load Center (CLC) falls below 11.2 V when the engine’s speed is between 512 rpm and 1500 rpm. Such a voltage dip could imply inefficiencies in the charging system or excessive power draw during mid-range engine operations, potentially affecting vehicle performance and electrical system stability.

Reaction:

The system may reduce the performance of certain functions or temporarily disable non-essential electrical components to conserve power and protect critical systems.

Recommendations:

• Evaluate Charging System Performance: Perform a detailed check of the alternator and associated charging components to ensure they are operating effectively across all engine speeds.
• Identify and Minimize Unnecessary Loads: Review all electrical loads to ensure no excessive power consumption occurs, particularly at mid-range engine speeds.
• Monitor Voltage Fluctuations: Continuously monitor voltage levels during different engine conditions to identify any anomalies that may not be apparent during idle or high-speed operation.
• Consult a Specialist: For recurring issues, a consultation with a John Deere specialist or a professional service technician is advised to delve deeper into the electrical system’s behavior.

Note:

Proactive management of electrical supply and demand is key to ensuring optimal performance and longevity of vehicle electronics, especially in fluctuating engine conditions.
