    Nothing is ever easy. I got my green car back together after a front end wreck. The bags didn't deploy, but the dash light is flashing. I've jumped the OBDII pins to read the DTCs and nothing changes - the light continues flashing the same way - about 1 second on, one off. I jumped the pins to clear any DTCs and nothing changed.

    The manual keeps telling me to swap the srs ecu, that's its solution for almost everything, but it just doesn't feel right. I think the wreck did something to one of the sensors. what a pain.

    I got another one with a solid light, but I did swap the bags on it. Hopefully, I can clear the codes on that one.

    That's an unusual pattern—it isn't any DTC, and it also isn't the "got no DTCs" pattern. I'm thinking the manual should mention such a pattern specifically. What does it have to say about it?

    I didn't see anything. It says the normal pattern is .25 seconds on, .25 seconds off. Or, if it was part of a DTC pattern, there would be a 4 second pause at the end of the codes before repeating, and it doesn't do that either. Just 1 sec on, 1 sec off.

    I'm going to swap the SRS ecm, just haven't gotten around to it yet.
