Description:

This fault code is issued when the Cab Load Center (CLC) control unit’s circuit board temperature exceeds 115 °C (239 °F) for more than 2 seconds. This critical temperature level can cause severe damage to the circuit board, potentially leading to failure of electronic components, degradation of circuit integrity, and a risk of fire.

Reaction:

The system may initiate protective measures such as shutting down non-critical functions to prevent further temperature increase and potential damage.

Recommendations:

• Immediate System Cool Down: Shut down the system if possible to allow the circuit board to cool.
• Inspect for Ventilation Issues: Ensure that the CLC is properly ventilated and free from dust or obstructions that could impede cooling.
• Check Cooling Mechanisms: Verify that any fans or other cooling systems are functioning correctly.
• Review Load Conditions: Reduce electrical load on the circuit board if it is determined to be a contributing factor.
• Assess and Repair Damage: Once cooled, assess the circuit board for any signs of thermal damage and make necessary repairs.

Note:

Preventive maintenance, including regular checks of temperature and electrical load, is essential to avoid such critical overheating conditions.
