As in this question, my SRS light keeps coming on. I read the code using a paperclip in the OBDII connector, which is always code 7-2 "Internal failure of SRS unit", and then reset it using the SRS connector. It stays off for weeks or months and then comes back on. Any idea how to troubleshoot this? Or do I have to take it to a mechanic? Obviously messing around with airbags is dangerous if you don't know what you're doing.
