CCU 000110.04 – Engine Coolant Temperature Signal Out of Range Low
CCU 000110.04 (CCU 110.04)
Code: 000110.04
Shortcode: 110.04
Description:
This fault code is triggered when the Chassis Control Unit (CCU) detects that the engine coolant temperature signal is lower than the normal operating range. This condition indicates that the engine may not be reaching optimal operating temperature.
Reaction:
The engine’s functionality is adjusted to compensate for the low coolant temperature, potentially affecting fuel efficiency and emissions.
Recommendations:
- Verify Coolant Level:
- Ensure that the coolant level is within the recommended range. Add coolant if necessary.
- Inspect Coolant Temperature Sensor:
- Check the coolant temperature sensor for proper operation. Ensure it is not damaged or malfunctioning.
- Check Thermostat:
- Verify that the thermostat is functioning correctly and is not stuck in an open position.
- Monitor Engine Temperature:
- After addressing any issues, reset the CCU and monitor the engine temperature to ensure it reaches and maintains the optimal range.
Note:
Maintaining proper engine temperature is crucial for optimal performance and efficiency. Regular checks of the cooling system and thermostat can prevent low temperature conditions.
