I have no problems mate I try to help.
I tested few FEM and possible to damage the chip.
- using official BMW EXPLORER table connection you will burn the chip.
- using cheap programmer with clip ( no disoldering) you will kill the chip.

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

using official BMW EXPLORER table connection you will burn the chip

is bullshit

using cheap programmer with clip ( no disoldering) you will kill the chip

is the same

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.

So what best choice to work with FEM BDC?

I think people dont understand, that if was not explorer, it would not be other cheappest tools - another word clones because process was born in Russia

I don't think you can have FEM virginized...

Which tool you used?

You didn't have the original backup?

[dashtool2016]

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

[dashtool2016]

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
