General Multiecuscan for airbag light barchetta 95

can someone give me data on voltages and resistances to be able to check the airbag ecu?
 
https://v4.barchetta-lexikon.de/index.php/lexikon/c/crash-sensor

i would try to get some one with the knowlage to fix it , if you can not it's not going to be worse than it is ... i would replace the 3 large electrolitic capacitors that are known to fail with time , then you can check for obvious damage in circuit components and finaly give the pcb a good brush with alcool and put it in the oven at 80 to 90ºc for some 10 min and try it on !!
these last resource tricks have worked out for me some times !!
 
apparently the printed circuit is well without signs of burns or heating. I would like to know voltage and resistance values ​​of the different mechanisms connected to the ecu as well as voltage line k to be able to have references and know if my ecu fails.
 
in the workshop book there is only wiring diagram but not parameter values.
 
i just know the resistance value from the emulators /resistors used to simulate the airbag and pretensioners squibs is around 3.3ohm
and ofcourse the 12v power !
try to get the ecu availability and price from here it's a very popular site around here :http://www.barchettaparts.com/catalog/

Yes l dos know barchettaparts. Thanksgiving for your informaron. I supossed 3.3 Ohm was actuators values.
 
yes it is . but for what i know values betwen 2 and 4 ohm are aceptable .

I have just used this chap from ebay -

cwautodiagnostics

I contacted him to confirm which cables I needed, these - https://www.ebay.co.uk/itm/144489808013, then bought them from him

Crucially for me as my IT skills are limited, he offers tech support. He even offers remote access support. He logged into my laptop (numerous times), to help me get connected to the air bag ecu.
My big issue was I couldn't connect to the ecu, this ultimately was due to a USBC to USB adaptor blocking the signal.
I used my sons laptop with USB and we got it working.
I cannot praise this chap enough, it took a few days and in total a few hours to resolve all the issues and get the connection to work, the port setting etc alone are minefield!
All for £17.99 :)
