Description:

This diagnostic trouble code is generated if the control software registers that the current at the output to the left outer worklight on the front of the roof, left turn-signal light on the front of the roof (SAE), or left extra-wide vehicle turn-signal light (SAE) is too low. This indicates that the circuit is open.

Reaction:

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

Recommendations:

• Inspect Light Circuit:
  • Check the wiring and connectors associated with the left outer worklight, left turn-signal light, or left extra-wide vehicle turn-signal light for signs of open circuits. Look for disconnected or loose connections. Repair or replace any compromised wiring or connectors.
• Test Lights:
  • Test the left outer worklight, left turn-signal light, or left extra-wide vehicle turn-signal light to ensure they are functioning correctly and drawing the proper current. Replace any faulty light components.
• Verify Power Supply:
  • Ensure the power supply to the lights is stable and within the specified range. Inspect for any issues that could cause a drop in current.

Note:

An open circuit can prevent the lights from functioning properly. Regular inspection and maintenance of the electrical system are essential to ensure reliable operation.
