Hi guys !
I have big problem with srs module.
After clearing crash data module is not visible to the car .There is no communication,
Does any one experienced similar problem ?

It looks like a bad file or hardware problem..

I've came across this fault before, if "low battery, eco mode" is on dashboard it won't power airbag ECU.

Ended up taking ECU out of the car and testing on bench and it communicated ok >.> Charged battery for 30 mins started engine all lights went out.
