Description:

Error code BCU 002360.01 is activated when the Power Module (High Frequency) PC6 in a John Deere vehicle measures less than 3 volts at the supply voltage for the output of the rear-facing worklights on rear fenders (lead 0222) while they are switched on. This low voltage condition typically suggests a power supply issue, which could be due to poor wiring connections, degraded wires, or faults within the power module itself, affecting the proper functioning of the rear-facing worklights.

Reaction:

The system may respond to this low voltage by disabling the rear-facing worklights to prevent operation under inadequate power conditions, which could lead to improper lighting performance or damage to the electrical components.

Recommendations:

• Inspect Wiring and Connections: Examine the wiring and connections from the power module PC6 to the rear-facing worklights. Look for any signs of damage, wear, or corrosion that might be causing the low voltage issue.
• Test Power Module Output: Measure the voltage output at lead 0222 using a multimeter while the rear-facing worklights are activated. This test will help confirm the low voltage condition and aid in pinpointing the cause.
• Check Ground Connections: Ensure that all ground connections related to the rear-facing worklights and power module PC6 are secure and free from corrosion. A poor ground can result in low voltage readings.
• Replace or Repair Faulty Components: If any components of the wiring or power module are found to be defective, repair or replace them to ensure reliable power delivery to the worklights.
• Verify Current Draw Post-Repair: After repairs are made, measure the current draw of the rear-facing worklights to ensure that it meets the expected operational range and that the worklights are functioning correctly.
• Reset the Power Module and Clear Diagnostic Codes: Reset the power module PC6 to clear any diagnostic trouble codes and retest the system to ensure the worklights operate correctly without further issues.
• Monitor System Operation: Keep an eye on the rear-facing worklights to ensure no further issues of low voltage or open circuit arise, confirming the stability and reliability of the repairs.

Note:

Regular inspections and maintenance of vehicle lighting systems are crucial to ensure they function efficiently and reliably. In the case of worklight systems, which are essential for safety and operational effectiveness, addressing issues promptly can prevent larger system failures and ensure ongoing visibility for the operator. By maintaining electrical integrity, the risk of operational disruptions and potential safety hazards is minimized.
