Help needed desperate to read Tssop 8 EPROMs - cyb0r - 03-05-2021

Hi Guys can anyone help.

Been trying to read and dump Tssop 8 EPROMs from 2  airbag modules

Pics attached 
One marking 
T34 2201
Other
 T34. 2501

Both chips are exactly the same 
One Fiat Bravo 2 from 2009   Siemens. 51775405 
One Fiat 500 from 2008  ecu number   Siemens 51782985


They are meant to be 95320 however none read in any flash reader. 
I have modified a ch341A to 5v and still no read outs, just F,S or 0,S

Absolutely lost how to dump the files to remove crash data.

@cyb0r you are sure that these tssop ic are memory 95320 ? You searched at the oposite side of pcb ?

Thank you my friend I was indeed reading wrong chip. The chip in photo turns out to be buffer chips.
I looked opposite side pcb and found 2530. Was hidden under some sort of dark varnish which I suspect is water proofing.

Chip all read and done. Thank you so much

Thank you so much my Friend, A good lesson learned to pay attention and fully check the board. Photos highly appreciated.

Found and sorted.
