Description:

This code indicates that the Instrument Cluster Control (ICC) unit detects that the light bulb output driver is out of calibration, causing erratic, intermittent, or incorrect data. This could be due to a malfunctioning driver, wiring issues, or a fault in the ICC unit itself.

Reaction:

The lights controlled by the affected driver may flicker, fail to illuminate, or behave unpredictably, potentially leading to visibility issues and safety concerns.

Recommendations:

• Inspect Light Bulb Drivers:
  • Check the light bulb output drivers for proper operation and calibration.
  • Replace any drivers that are malfunctioning.
• Examine Wiring and Connectors:
  • Inspect the wiring harness and connectors for signs of damage, corrosion, or loose connections.
  • Repair or replace any damaged components.
• Test ICC Unit:
  • Use diagnostic tools to verify the functionality of the ICC unit.
  • Update or reprogram the ICC unit if necessary.
• Verify Bulb Function:
  • Ensure the bulbs themselves are functioning correctly and are of the correct type for the system.

Note:

Regular maintenance of the vehicle’s lighting system and prompt replacement of faulty components can help maintain proper operation.
