RLC 002352.03 – Low Beam for Headlights on Cab Frame, Voltage Too High

RLC 002352.03 (RLC 2352.03)

Code: 002352.03

Shortcode: 2352.03


This diagnostic trouble code is generated if a voltage higher than 16 volts is registered at the output to the headlights (low-beam) on the cab frame. This indicates a short circuit to a positive lead.


When this error is detected, the control software may experience limited or no functionality of the low-beam headlights on the cab frame.


  • Inspect Headlight Circuit:
    • Check the wiring and connectors associated with the low-beam headlights on the cab frame for signs of short circuits to a positive lead. Look for damaged insulation or exposed wires. Repair or replace any compromised wiring.
  • Verify Voltage Regulation:
    • Ensure the voltage regulator is functioning correctly and maintaining proper voltage levels. Replace the regulator if it is faulty.
  • Test Headlight Components:
    • Test the low-beam headlights to ensure they are not damaged or causing the voltage increase. Replace any faulty headlight components.
  • Check Power Supply:
    • Ensure the power supply to the headlights is stable and within the specified range. Inspect for any issues that could cause an overvoltage condition.


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