SUBJECT: Lit PASSENGER AIRBAG OFF indication with belted adult passenger
REFERENCE: VIDA

DESCRIPTION:
Customers may experience a lit PASSENGER AIRBAG OFF indication in the overhead console (S40, V50, C70, S80 MY07) or interior rear view mirror (S60, S80 MY06, V70, XC70, XC90) with a belted adult passenger in the front passenger seat. When this happens, the PASSENGER AIRBAG OFF indication will typically remain lit until the passenger unbuckles the seat belt or moves out of the seat.

This could be caused by vibrations on the bracket for the Occupant Weight Sensor (OWS) control module. Follow the attached instructions only after all other root causes (e.g. the hose from the OWS bladder must not be kinked, twisted or otherwise restricted) have been ruled out using the fault tracing in VIDA.
