Description:

Error code BCU 002360.00 is triggered when the Power Module (High Frequency) PC6 in a John Deere vehicle detects a total amperage exceeding 40 amps across the E3 and H1 outputs, specifically affecting the E15 rear-facing worklights on rear fenders. This diagnostic trouble code is associated with an overload condition that may be due to a short to ground or a defective component within the circuit, posing a risk of overheating and potential damage.

Reaction:

Upon detecting this excessive current, the system activates overload protection, which may disable the affected worklights to prevent further electrical damage and ensure safety. This protective action helps mitigate the risk of electrical fires or component failures.

Recommendations:

• Inspect Worklights and Wiring: Examine the rear-facing worklights and their wiring for any signs of damage, wear, or corrosion. Focus on identifying potential causes of a short to ground, such as exposed wires or connections that could be contacting metal parts of the vehicle.
• Measure Current Draw: Use a multimeter or a clamp meter to measure the current draw of the rear-facing worklights to verify if it indeed exceeds the normal operational range.
• Identify and Repair Short to Ground: Locate and repair any shorts to ground found during the inspection. This may involve tracing the wiring from the worklights back to the power module, checking for any pinch points, worn insulation, or improper routing.
• Replace Damaged Wiring or Components: Any damaged wiring, connectors, or components found during the inspection should be replaced to restore the integrity of the electrical system.
• Test After Repairs: After repairs are made, test the circuit again to ensure the current draw is within acceptable limits and that the worklights function properly without triggering the high current condition.
• Reset the Power Module and Clear Diagnostic Codes: Reset the power module PC6 to clear the diagnostic trouble codes and reactivate the worklights. Ensure that the system is functioning correctly and that no further fault codes are displayed.
• Monitor System Operation: Keep an eye on the operation of the rear-facing worklights to ensure there are no recurrences of the issue and that repairs have effectively resolved the problem.

Note:

Electrical safety in vehicle systems is critical, particularly in worklight circuits where high current can indicate serious faults. Regular maintenance checks, including inspections of electrical wiring and connections, are crucial to prevent issues such as shorts to ground. Addressing such problems promptly ensures the safety and functionality of the vehicle’s lighting systems, maintaining operational efficiency and preventing potential hazards.
