Problem with my 2003 Chevy Tahoe Truck
5.3 v8 Airbag Light

Question = My airbag light on the dash is on as well as my review mirror is not  working.  There
is a red light on the review mirror, I've checked the fuse its okay,  tried turning on the mirror but
nothing happens and the light for passenger airbag  on the mirror is not working.  I was told a
sensor or modular was not working  correctly under the passenger seat?  Is this true could I do
it, not sure if it is simple or need a technician.

Yes, it does sound like a problem in the passenger airbag system is causing the light in the
mirror and the light on the dash. This is called the "Passenger Presence System"The airbag
system would need to be scanned for codes to start diagnosis.

There is something you can check for yourself. There is a service bulletin for these conditions,
if you have a code B0092.

The harness for the passenger presence system may have rubbed through under the seat on
the seat frame. A wire may be pinched between the seat frame and the riser. I will send a pic of
its location shortly..... If there is a rubbed through wire, it would need to be repaired, then
disconnect the battery for a few minutes to clear the codes if you do not have access to a
Thanks again for the tip / donation.
Here is the pic of location of the problem area.
