Description
The EEM4 monitoring system has detected a too high internal ECU temperature.
Possible causes are:
The vehicle cooling system is defective.
Reaction in EEM
The FC is stored and the warning lamp is activated. The CAN message indicates active fault. The engine will stop after 30 seconds, if the ECU internal temperature is continuously >114 °C.
Solution
First save the error log and then erase it. Restart the ECU after erasing the error log. If the fault occurs again during the next driving cycle, check the following paths:
Let the engine cool down and then try touching the ECU by hand. If it is still very hot and the fault code is active, try to replace the ECU.
If there is a fault code in the fault log which indicates engine overheating, this fault code should heal after applicable time (ecu_t< 109°C).
Check the ECU operation with another EEM4 controller. If the system is functional and the fault is not active with the replacement ECU, then the original ECU is defective.
