BCU 002360.19 – E15 Rear-Facing Worklights on Fenders, Incorrect CAN Bus Message from Multiple Control Units. John Deere System Advisory.

BCU 002360.19 (BCU 2360.19)

Code: 002360.19

Shortcode: 2360.19

Description:

Error code BCU 002360.19 is triggered when the output for controlling the rear-facing worklights on rear fenders (E15) is simultaneously energized by more than one control unit, indicating a conflict or misconfiguration within the vehicle’s CAN bus system. This situation can lead to erratic behavior of the worklights, including unintended flashing or failure to operate as expected, due to conflicting signals received by the Power Module (High Frequency) PC6.

Reaction:

The system may respond by logging the conflict and potentially displaying a warning to the operator. Depending on the nature of the miscommunication, it might also temporarily disable the affected worklights to prevent erratic operation and reduce the risk of damage to the electrical system.

Recommendations:

  • Identify Contributing Control Units: Use diagnostic tools to determine which control units are sending conflicting signals to the E15 worklight output. This will help identify the source of the problem.
  • Inspect CAN Bus Configuration: Examine the configuration and programming of the CAN bus system to ensure that it properly routes commands to the worklights, preventing multiple control units from attempting to control the same output.
  • Resolve Configuration Errors: Correct any programming errors or misconfigurations discovered during diagnostics. This may involve reprogramming one or more control units to ensure only the appropriate signals are sent to control the rear-facing worklights.
  • Test Worklight Operation: After making adjustments, test the rear-facing worklights to ensure they respond correctly to control inputs and that no additional or conflicting commands affect their operation.
  • Reset the Power Module and Clear Diagnostic Codes: Reset the power module PC6 and any other involved control units to clear the diagnostic trouble codes and reestablish proper system operation.
  • Monitor System Post-Repair: Continue to monitor the rear-facing worklights to ensure that they function consistently without further signal conflicts. Verify that the corrective actions have resolved the issue completely.

Note:

Proper configuration of the CAN bus system to prevent command conflicts is essential for the reliable operation of vehicle systems. Regular checks and updates of the system configurations can prevent potential operational conflicts and ensure smooth operation of all connected devices. This is especially important in complex systems where multiple control units communicate over a common network, as misconfigurations can lead to unintended equipment behaviors and safety issues.
