Description:

Error code BCU 002360.12 is activated when the Power Module (High Frequency) PC6 in a John Deere vehicle detects a current of more than 1 amp at the output for the rear-facing worklights on rear fenders (E15), despite the worklights being switched off. This unusual current draw suggests a potential short circuit within the wiring or an internal fault in the power module, which could lead to unnecessary power consumption, potential overheating, or damage to the electrical system.

Reaction:

The system may not immediately react with operational changes but will record the fault to alert maintenance personnel. Persistent current flow when the lights are off can increase the risk of electrical fires or damage to the power module or worklights.

Recommendations:

• Inspect Wiring for Short Circuits: Carefully check the wiring associated with the E15 rear-facing worklights. Look for any signs of damage, wear, exposed wiring, or conditions conducive to short circuits.
• Measure and Diagnose Current Flow: Use a multimeter to verify the current flow at lead 1033 while the worklights are supposed to be off. Confirm if the measurement exceeds the expected 0 amps in the off state.
• Test Power Module Functionality: Evaluate the Power Module (HF) PC6 for any internal faults that could be causing unintended current flow. This may require specialized diagnostic tools to assess the module’s condition.
• Replace or Repair Faulty Components: Depending on the findings, either repair the wiring, replace the worklights if they are the cause of the short, or replace the power module if it is found to be defective.
• Reset the System and Clear Diagnostic Codes: After repairs are made, reset the power module and the BCU to clear the diagnostic codes and retest the system to ensure the issue is resolved.
• Monitor System Post-Repair: Keep a close watch on the operation of the rear-facing worklights and the overall electrical system to ensure no further issues of unintended current draw arise.

Note:

Ensuring that electrical systems are free from shorts and internal faults is critical for the safety and efficiency of vehicle operations. Regular inspections and proactive maintenance can prevent potential hazards and ensure that all components function as intended. Addressing electrical issues promptly when detected helps maintain the operational readiness and safety of the machinery.
