Airbag warning light - fault 31

[tcleaver]

The airbag light came on this week on my '99 996. Durametric says it is fault code 31 - ignition circuit, side airbag, passenger.

I tried to clear the fault with Durametric. The light does go off but comes back on after a few seconds.

Is this something i can correct or does it need to be done by the dealer?

Fault codes 14, 15, 30, 31, 41 -- Ignition circuit, passenger's side airbag

Possible cause of fault

- Short circuit to B+/ground or open circuit in the wiring between the passenger side airbag unit and the airbag triggering unit

- Passenger's side airbag faulty

- Triggering unit for airbag faulty

Thanks.

Is this referring to the passenger airbag in the dash? I've recently updated the stereo speakers, including the ones in the dash, so perhaps i knocked something when removing and replacing the right dash speaker. Possible?

Yes, passenger main airbag in the dash. So yes check the connections (carefully WITHOUT the key in the ignition).

Also check the control unit at the carpet level in the center console.

Ah. Then i suspect it is all related as i've been digging around in the center console a lot. Moved the ac controls down in place of the lower shelf, added cup holders above the head unit, changed the head unit to a cdr-220, ran several cables from the back of the head unit down through the firewall above the accelerator etc.

Where is the carped level control unit? Also if i remove the right dash speaker can i access the airbag connections through the speaker hole?

Thanks

Straight behind the center console at the tunnel (behind the radio and down).

No the passenger airbag is accessed from under the dash.
