There are two ways to enable the pre-discharge FET initially. Either through timeout or through a voltage condition set by Settings:FET:PredischargeStop Delta.
If using timeout, the PDSG FET will be enabled initially until the timeout time occurs, where the DSG FET gets activated. With a voltage condition the PDSG FET will be enabled initially until thePredischarge Stop Deltacondition is met, then it will transition to activating the DSG FET.
If the DSG FET is already active, the PDSG won't be activated unless the DSG FET is turned off and on again (This could be done through commands).
SeeSection 5.2.3.2.2 PREDISCHARGE Modeof theTRMfor a description and functioning of the PDSG function.
