Note for display field 3:

When a DTC relating to the Engine Coolant Temperature (ECT) sensor -G62- is stored in DTC memory, the Engine Control Module (ECM) starts using the intake air temperature as a replacement value when starting the engine (starting temperature replacement value). After this, the temperature rises according to a mapping specification stored in the control module. For a warm engine, a fixed replacement value is used after a certain period of time. This fixed replacement value is also dependent on the intake air temperature.

Note for display field 4:

The entire temperature range is indicated as a specified value. The indicated value must be above the ambient air temperature.
