Airbag light B0081 code

[tired2008tahoe]

I have a B0081 code, erratic signal. I cleared codes still there. Changed the sensors in the RF seat and it’s still there anyone has any suggestions on what to do in this situation?

Passenger presence system, it has a little air tube and actuator that clips on under the seat, probably need to replace that. when a passenger is present it creates air pressure and turns the passenger airbag sensor on

I replaced that and it still gave me the DTC

Right after that code, a symptom code should also be present if you have the right scan tool...

might have a broken wire somewhere under the seat area, check the wires with a meter while wiggling them, or maybe the replacement part is no good, @Rocket Man had a bad wire for the airbag I think

Symptom 71 do you know the fix?

Symptom 71 do you know the fix?

1. When DTC B0081 71 sets, inspect wiring and connections for a possible loss of
communication between the SDM and PPS module. Inspect front passenger seat connector to
the PPS module and seat connector to the seat harness. Do not replace the SDM module for a
DTC B0081 71 condition.
just like I said check the wiring
my 03 had a loose (broken) wire on the harness one time, very easy fix

Symptom 71 do you know the fix?

Verify DTC B0081 71 or B0081 0F is not set.
¤ If DTC B0081 71 or B0081 0F is set, verify the SDM is properly connected and communicating with the PPS. Clear the DTCs. No other repairs are necessary.

Mine shows this code (B0081-5A) very rarely. Once you crank the engine the message and the airbag light go out. Found out there's a TSB only for modelyear 2009 vehicles saying this behavior is normal if no other codes are present: TSB 08-09-41-009A
