RLC 002370.03 – Right Front Turn-Signal Light, Voltage Too High

RLC 002370.03 (RLC 2370.03)

Code: 002370.03

Shortcode: 2370.03

Description:

This diagnostic trouble code is generated if a voltage higher than 16 volts is registered at the output to the right turn-signal light on the front. This indicates a short circuit to a positive lead.

Reaction:

When this error is detected, the control software may experience limited or no functionality of the front right turn signal light.

Recommendations:

  • Inspect Turn Signal Circuit:
    • Check the wiring and connectors associated with the right front turn-signal light 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 Turn Signal Light:
    • Test the right front turn-signal light to ensure it is not damaged or causing the voltage increase. Replace any faulty light components.
  • Check Power Supply:
    • Ensure the power supply to the turn signal light is stable and within the specified range. Inspect for any issues that could cause an overvoltage condition.

Note:

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