Air Bag code B1811 - clock spring?

Hey Guys,

Of course, the air bag warning light is coming on in my daughter's 05 base vibe. It sometimes stays on when the car is started and other times it goes out then comes back on after a few minutes of driving. My local shop hooked it up to their computer and the only stored code is B1811 "High Circuit".

Google revealed this doc: http://share.qclt.com/%E4%B8%B0%E7%94%B ... 181153.pdf

CIRCUIT DESCRIPTION
The D squib (Dual stage – 2nd step) circuit consists of the airbag ECU assy, the spiral cable sub–assy and the horn button assy.
The circuit instructs the SRS to deploy when deployment conditions are met.
DTC B1811 is recorded when an open circuit is detected in the D squib (Dual stage – 2nd step) circuit.

This "spiral cable sub-assy" is the "clock spring" is it not?

Yes, I do believe "spiral cable sub-assembly" is Toyotaspeak for clock spring.

If that's the source of the failure that would be the ideal outcome considering it's the cheaper component to replace. Hopefully it's not in the driver's air bag module!
