XC43 Output High
we have strange behavior which XC43 Has constant high output as soon as get powered on ,
we have replaced 3 modules but the same situation was income .
temporarily that output sealed and waiting for your advise .

Did you have load on that output when measuring it?
XCxx outputs have some leakage current which seems that output is always on when measuring it with multimeter.
You may need to add a pull down resistor to get it off state.
this was my first thinking , I made a dummy like , lamp to See it is going off but lamp was constant on ,
Which output? If it is a digital HS there is leakage through them for error checking (for open load detection). Much higher current leakage than the XA2's.
OK THEN .
it WAS DO , HS ,
If you are trying to drive LED headlights, you will have to install a power resistor between the HS output and ground, otherwise they will light up slightly due to current leakage.
Got it , thanks
