Only OBDII /EOBD codes will trigger the SES/CEL/MIL. Manufacturer proprietary codes WILL NOT light the SES/CEL/MIL, they may light some other type of warning, but usually they will not light anything and not notify the driver.
I RARELY care to get anything other than OBDII/EOBD codes when working on driveability problems. Manufacturer proprietary codes are not often required and will often confuse matters due to poor language translation and/or the semantics. I the glass half empty or half full based on someone's point of view.
Unless I misunderstood the question, the OP should start with the OBDII/EOBD function of the tool first.
