Error code ECU 000111.18 indicates that the coolant level is low while the engine is operating at moderate temperatures. This condition might not trigger immediate overheating but can lead to potential issues if coolant levels continue to decrease.

READ MORE

Error code ECU 000111.17 is activated when a low coolant level is detected by the ECU, warning of insufficient coolant to maintain optimal engine temperature and function.

READ MORE

This code, ECU 000111.07, is set off when the coolant level switch malfunctions, indicating a lower than actual coolant level. This may result in unnecessary engine safety precautions or alerts.

READ MORE

ECU 000111.01 indicates a critical condition where the coolant level is low while the engine is operating at high temperatures. This can lead to overheating and potential engine damage if not swiftly addressed.

READ MORE

Error code ECU 000110.17 is triggered when the engine coolant temperature does not reach the expected operational range, indicating it remains unusually low. This could suggest issues such as a stuck-open thermostat, excessive coolant volume, or inadequate engine load.

READ MORE

Error code ECU 000110.16 indicates that the engine coolant temperature is consistently above the specified limits by a moderate margin. This condition requires timely intervention to prevent overheating and potential engine damage.

READ MORE

This code, ECU 000110.15, is raised when the engine coolant temperature slightly exceeds the normal operational range. While not immediately critical, it suggests the onset of potential cooling system inefficiencies or early signs of mechanical issues.

READ MORE

ECU 000110.04 signals that the engine coolant temperature sensor’s input voltage has dropped below the specified minimum, suggesting a short to ground. This fault typically results in lower than actual temperature readings being reported to the ECU.

READ MORE

Error code ECU 000110.03 is triggered when the input voltage for the engine coolant temperature sensor exceeds the highest specified rating, typically indicating a short to a 12-volt power source. This malfunction can lead to erroneous high temperature readings, which may mislead the engine control system.

READ MORE

ECU 000110.00 is activated when the engine coolant temperature rises above the specification limit, signaling potential overheating. This extreme temperature could be due to several factors, including coolant depletion, radiator blockage, or malfunctioning cooling components.

READ MORE

Error code ECU 000109.31 is reported after the coolant pressure signal was noted as slightly low during a previous operation cycle. This recurrent low reading could be an indicator of persistent issues within the coolant system that require immediate attention.
