RE: Airbags inflated CAN message?

I suspect you "can't get there from here."
 
I see 2 problems: first, the complete inflate/deflate cycle doesn't last very long; the numbers I see show a max of 25 milliseconds for inflation, with deflation beginning immediately thereafter.  Catching a message when it is actually inflated is probably a lost cause (yes, you'd have to crash the car or at least trigger the air bag(s)).  However, there may be a message that indicates it had been activated.
 
Which brings us to the second issue: many (most?) manufacturers use their own proprietary CAN protocols.  Even if they are using something like the SAE J1939 standard, they might "hide" the indicator within a proprietary message.  Either way, even if we knew where it was, we couldn't tell you.  But it won't be a generic solution.  As an aside, I don't see such an indicator in J1939 but my docs are way old.
 
As for connecting to the OBD port and reading error codes, OBD/OBD II is oriented towards emissions controls.  From what I can find on the 'net, air bag status(es) aren't included.

Hi

I need to know if the air bags in the car are inflated

I guess this data runs over CAN but i can't detect it via regular sniffing (crash the car???)


This goes for as many cars as possible (e.g. hyundai I20,  Toyota outlander etc) as this is for a generic application 

Best solution may not involve connecting to the OBD and reading error codes


can anyone advise?

Best Regards
