RLC 521562.06 (RLC )

Code: 521562.06



This diagnostic trouble code is generated if the control software registers that the current at the output to the right inner worklight on the rear of the roof or right Xenon (HID) worklight on the rear of the roof is too high. This indicates a short circuit to ground.


When this error is detected, the control software may experience limited or no functionality of the worklight.


  • Inspect Worklight Circuit:
    • Check the wiring and connectors associated with the right inner worklight or right Xenon (HID) worklight for signs of short circuits to ground. Look for damaged insulation or exposed wires. Repair or replace any compromised wiring.
  • Test Worklight:
    • Test the right inner worklight or right Xenon (HID) worklight to ensure they are not damaged or causing excessive current draw. Replace any faulty light components.
  • Verify Power Supply:
    • Ensure the power supply to the worklights is stable and within the specified range. Inspect for any issues that could cause an overcurrent condition.


Excessive current can damage the worklights and associated circuitry. Regular inspection and maintenance of the electrical system are essential to prevent such issues.
