and just saw your post.
pcmahar is correct, the system is digital and needs a scanner to read out codes. So I take it that your SRS light is on??
Personally, I always said that one SHOULD be able to read the 'pulses' with an oscope but it MUST be one that can be triggered by the 'start' of the event you are trying to measure AND that it is a STORAGE scope. You set it up to start a SINGLE sweep from an external trigger, so you see a single 'flash' on the screen. Then you recall the 'event' and can now count the pulses.
But when I set off my SRS light (during my fix of the SBE, MENU#25), I used an AST Retreiver to read the code (just one, "#3") and then reset the light and code. The SRS system is DIGITAL in my car, so impulse reader won't work nor will a DVM/DC meter.
