OK, i want clear this bullshit and show u something to learn. All your future questions will disappear .
If we talking about BDC
By scheme of explorer we have +12 on socket A258*1B and "-" on socket A258*2B pin 6

From this we can see that A258*1B is
Supply, terminal 30 Fuse F504
A258*2B pin6 is
6 A Actuation, control valve A/C compressor
And there is another scheme, where "+" and "-" in socket A258*7B where
pin number 1 is
1 A Power supply, terminal 30F Heating/air conditioning system
and pin number 4 is
4 M Ground Heating/air conditioning system
As we can see in any way fem\bdc gets power supply.
So now i can state the fact that
is bullshitusing official BMW EXPLORER table connection you will burn the chip
is the sameusing cheap programmer with clip ( no disoldering) you will kill the chip
I plugged by all this schemes and everything is ok !!!!!
Best regards !!!
dunno if this helps:

also, i read 95xxx eeproms in circuit and have not had any corruption, but agree that safest method is to remove the chip and read.

hello friends i need to return the fem unit to its original state i can not access it with ista / p i get error in terminal 15 it has no voltage
the problem that I can not recover it with is it possible to recover it with e-sys still not communicating? Can someone help me please ? Is it possible to virginize it?
I have the original copy of eeprom and the coding read with yanhua but now I try to read with the tool the fem in the bank and it does not let me read it and in the car either and I do not know how to return it to the original state: S
anyway it has to be comunnication even when u have FFFFF swfl status in FemBody
and tried with ista-p to apply the plan of measures but without success the car works everything but it seems to be protected because ista or yanhua does not connect with the unit fem
