I have a 2003 mitsubishi magna that recently had an srs airbag light come up after using the horn. I have tried to scan but the obd2 would not connect to get trouble codes Can you advise what might be the issue and is it safe to drive?
A generic OBD2 reader won't see SRS codes. The problem is likely a bad clockspring.
is it safe to drive?
The supplemental restraint system (SRS) is crippled
An additional thought if your clockspring isn't the issue. My 2006 Toyota Matrix used to show intermittent SRS warnings, and also the front passenger seat was overly sensitive to weight. I noticed if I slapped the dash and restarted the car, everything worked fine. In my case, I fortuitously discovered the problem turned out to be the dash module containing the clock, which also runs the SRS stuff. I had that module resoldered and tested (apparently the solder joints can fail after enough years). That fixed the problem. I imagine that, like mine, your issue could be a bear to diagnose, although the source of your problem could be different. Good luck!
