OBC airbag failure message - car would not start

Recommended Posts

Something strange happened to my Boxster (S 2003) today. After a 30 miles drive I parked my car at a shopping mall and when I came back, the car wouldn't start anymore.

There is no ignition sound at all. After a few seconds, I got a airbag failure message on my OBC. Note that there is NO airbag warning light, just the OBC message. I don't have diagnostic tool to read the error code....

I tried a few things:

* Start car using a battery recharger device -- same result. Everything on the car powers up fine include my soft top so should not be a battery issue.

* Start my car using another remote key -- same result. Does not seem like a remote/immobilizer related issue

* Disconnect the car battery for 15 minutes -- same result. Problem persists.

* Clutch depressed several times or at different depressed positions

Some major work on my car that might me relevant:

* I had to repaint the passenger side door over a year -- could some issue with this door airbag creep up on me after over a year?

* I changed my clutch half a year ago. This is may affect more of the cut-off switch but not related to the airbag message...

Could an issue with airbag actually stop my car from starting up? I read articles where the airbag message or warning light only serve as an alert and does impact other functions of the car.

Embarrassingly it turns out that the ignition switch screws got loose over the several months of use after my replacement. Once I tighten it back up, the car is able to start up again and the airbag message went away.
