Description:

This diagnostic trouble code is generated if the control software registers that the current at the output to the backlighting is too high, indicating a short circuit to ground.

Reaction:

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

Recommendations:

• Inspect Backlighting Circuit:
  • Check the wiring and connectors associated with the backlighting for signs of short circuits to ground. Look for damaged insulation, exposed wires, or loose connections. Repair or replace any compromised wiring.
• Test Backlighting Components:
  • Test the backlighting components (e.g., bulbs, LEDs) to ensure they are not drawing excessive current. Replace any components that show signs of damage or excessive current draw.
• Verify Power Supply:
  • Ensure that the power supply to the backlighting circuit is stable and within the specified range. Check for any issues that could cause an increase in current.
• Update Control Software:
  • Ensure the control software is updated to the latest version to address any potential issues with current monitoring.

Note:

Excessive current in the backlighting circuit can lead to damage of the lighting components and related circuitry. Regular inspection and maintenance of the backlighting system are essential to prevent such issues.
