CLAAS 772Dh – Claas Eng A15 Engine Module: Engine Coolant Temperature Averagely High

The engine coolant temperature is higher than normal, causing the engine module to reduce power gradually. The power reduction is 5% per minute until it reaches 80% of its nominal power, and power is recovered at 5% per minute once the temperature returns to normal.
