Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
There is a bulletin about this issue.
This bulletin is being revised to update the model years. Please discard Corporate Bulletin Number 09-09-40-003 (Section 09 - Restraints).
Some customers may comment that the SIR light is illuminated. Upon investigation, the technician may find the following SDM code stored:
DTC B0081 71: Passenger Presence System Invalid Serial Data Received With Passenger Presence System (PPS) Flash Code of DTC 023
The wire on the Belt Tension Sensor (BTS), that is part of the retractor assembly, may become open or acquire a ground near the sensor. If the BTS is rotated toward the rear of the vehicle, added stress is applied to the wire bundle that may cause an open or a ground path. The two photos below illustrate the possible effects on the wiring. Each photo indicates the area to investigate at the arrow labeled (1).
Important: Technicians are to inspect the electrical connections to all the PPS components.
Important: DO NOT retape the BTS connector (retainer is located 200 mm (8 in) rearward of the connector) to the harness. DO NOT re-install the BTS to body retainer (refer to Figure 6).
Important: Use a temporary marking pen so that excess can be washed off after the modification is made.
I have a 2006 cobalt vin 1g1al18fx67622298 air bag lite is on code b0081 looking to gm sub code or any info as to the problem thanks bob
It is likely that wiring at the passengers seat belt buckle.
Look at the plastic around the base of the buckle and see if the wiring is chaffed on it
Allready checked they seem to be ok
Are you able to get the code descriptor?
the only code we get is passenger presence system #1
But was there a 2 digit code after it?
Did you use a scan tool to get the flash code from the passengers presence system?
our tool will not allow us to do this
Ok, then you may need a full scan tool to get that so we are on the proper path.
we have a new full scan tool but it will not allow us to go any further
What brand of tool
Ok, any access to a GM one?
not at this time
Not much I can suggest then until we get the PPS code.
