ACU 000237.31 (ACU 237.31 ) – VIN Security Messages Missing

ACU 000237.31 (ACU 237.31)

Code: 000237.31

Shortcode: 237.31


This error code ACU 000237.31 indicates that VIN security messages are missing, which occurs when the Vehicle Identification Number (VIN) is not received from other control units. This situation can arise due to communication errors or misconfigurations in the network linking the control units.


The absence of VIN security messages leads to degraded functionality of the control unit, limiting some operations to prevent incorrect functioning and potential system damage.


  • Check the communication links between control units to ensure they are intact and functioning properly. This includes inspecting wiring and connections for faults.
  • Verify the configuration settings in each control unit to ensure they are set to transmit and receive VIN information correctly.
  • Use diagnostic tools to monitor the data traffic between control units to detect any anomalies or failures in data transmission.
  • If problems persist, consult with a John Deere technician for a more thorough examination and potential system reset or updates.


Continuous failure to receive VIN security messages can lead to significant operational limitations. Addressing this issue promptly is crucial to maintaining the overall health and efficiency of the machinery.
