Description:

This fault code indicates that the Cab Load Center (CLC) control unit has detected an open circuit in the left or right rear roof flood lights, resulting in low current flow. An open circuit often suggests a disconnection or failure in the wiring or connectors, leading to non-operational flood lights.

Reaction:

The rear roof flood lights will not operate due to the open circuit condition, affecting visibility in low light conditions.

Recommendations:

• Check Wiring and Connectors: Inspect the wiring and connectors for any signs of damage or disconnection.
• Circuit Testing: Use a multimeter to test the continuity of the flood light circuit to locate any breaks or faults.
• Ensure Proper Programming: Confirm that the lights are programmed to be operational as per the Programmable Lighting Operational Check.
• Repair or Replace Faulty Components: Repair any faults found during inspections or replace damaged components as necessary.
• System Testing: After repairs, test the system to ensure that the rear roof flood lights are fully operational.

Note:

Regular maintenance and checks of the lighting system can prevent issues related to open circuits and ensure safety through adequate lighting.
