Forced adaptation
Using the diagnostic tool the ECM can be forced to perform ethanol adaptation. This may be necessary, for example, following a repair that caused an incorrect ethanol adaptation and the fuel's ethanol content is not known.
Connect the diagnostic tool and contact Trionic, select the BioPower menu, and force ethanol adaptation. The engine's coolant temperature must be in excess of +60°C in order that adaptation should start. The diagnostic tool shows the ongoing status.
If the temperature is too low then this is indicated by the display. Forced ethanol adaptation requires approx. three minutes and can be performed at idling speed or while driving.
Following forced adaptation the ECM must not be disconnected or in any other way be de-energised. Otherwise the adapted value will not be stored in the memory. Instead the previous value for ethanol adaptation will be used.
