BCU 002354.00 – Front Corner Worklights Current Overload. John Deere System Advisory.

BCU 002354.00 (BCU 2354.00)

Code: 002354.00

Shortcode: 2354.00


Error code BCU 002354.00 is triggered when the Power Module (High Frequency) PC6 in a John Deere vehicle measures a total amperage exceeding 40 amps at outputs E3 and H1. This specific code relates to the E09 front corner worklights (both right and left). The excessive current draw typically indicates a short to ground or a defective component within the circuit of these worklights. Such conditions not only risk damage to the electrical system but can also affect the functionality of the lights and potentially lead to further electrical issues.


Upon detecting this overload, the system activates current overload protection to prevent damage by temporarily shutting down the affected outputs. This safety feature helps protect the wiring and components from overheating or further damage.


  • Inspect Worklights and Wiring: Check the front corner worklights and their wiring for signs of damage, wear, or corrosion. Look for any indications of a short to ground, such as exposed wires touching metal parts of the vehicle.
  • Test Electrical Components: Use a multimeter to measure the current draw of the front corner worklights. Compare the actual amperage to the specifications to identify if the current draw is within a normal range.
  • Replace Defective Worklights or Components: If any worklights or associated components are found to be defective, replace them to resolve the issue of excessive current draw.
  • Check Related Outputs: Since the outputs E3 and H1 are monitored together, also check the E15 rear-facing worklights on rear fenders as covered by diagnostic trouble code BCU 002360.00, to ensure there are no additional issues contributing to the overload.
  • Reset the Power Module and Clear Diagnostic Codes: After repairs are made, reset the power module PC6 to clear the diagnostic trouble codes and restore normal operation. Recheck the system to ensure that the overload protection does not reactivate.
  • Monitor System Performance: Continue to monitor the electrical system, particularly the affected worklights, to ensure no further issues occur. Verify that all replaced components function correctly and that there is no recurrence of the overload.


Regular maintenance and checks of the vehicle’s electrical system are essential for ensuring the reliability and safety of its operations. Addressing issues like current overloads promptly helps maintain the functionality of critical worklight systems and prevents potential hazards associated with electrical faults.
