LadyVolFan L My 2007 Sky recent started giving me the message "Service Air Bag" with the light on in the dash. It is out of warranty so I took it to a local mechanic today. He ran a diagnostic and got the following... Air Bag Code B0081, Symptom 71, Passenger Presence System Invalid Serial Data. He wants to try to fix it. Should I let him work on it or take it to a Chevrolet dealer? Does anyone know what this message means or what will be required to fix this? Thanks #1 · Feb 22, 2011 My 2007 Sky recent started giving me the message "Service Air Bag" with the light on in the dash. It is out of warranty so I took it to a local mechanic today.

Could be as simple as a wiring connector issue or the whole module might need to be replaced. I can't be sure. #3 · Feb 24, 2011 Thank you for your response. I'm not sure how confident he is but I know he will do his best. I am praying that it's just a wiring issue. I saw the $1000 + article. I was sure someone here would have gotten the same code so I'd know what I was dealing with. It may be that no one was never told the code. 0 Reply #4 · Feb 25, 2011 Most people don't get the codes when they have their car repaired. Just remember that the airbags may not deploy if the airbag light is on. IIRC from what I read your passenger air bag is disabled if this code is present. Get it fixed properly and promptly. #5 · Feb 26, 2011 in my case (and some others I have read) it is the sensor on the passenger seat. here is a copy of what I paid, don’t let this happen to you!!!

#6 · Mar 2, 2011 Yes, I saw that bill a while back and that's what scared me. It is in the shop as of this morning. I am SOOOO hoping that it's a wiring problem and not that sensor. I'll let everyone know what I found out, hopefully soon. #7 · Mar 7, 2011 I have the same code on my 2007 Saturn Sky Redline. It threw the code during a hard shift (manual) from 1st to 2nd. Any updates on the repair by Lady Vol Fan? #8 · Mar 11, 2011 Well, it was the sensor on the passenger seat. Total bill $634.06. #9 · Mar 31, 2011 I have the same code on my 07. Dealership said it was the wiring and not the sensor. It's still $300. My uncle is my auto mechanic but is only an ASE teacher so hopefully he can do it. I haven't spoken to him about it yet, but does anyone know where the wiring can be purchased and how invasive it is? #10 · Apr 1, 2011 (Edited) There's two parts to this... the module bolted to the floor under the seat, and the sensor mat glued on top of the passenger seat cushion. The module is easy to replace (might have to unbolt the seat first, but I doubt it). For the mat, the seat would have to come out and you'd need to remove the bottom cushion cover - still not hard though. Worst piece is that you need to run the 'reset/training' procedure with the TechII tool after you replace either of them. For that you need the tool which only a dealer is likely to have (though some mechanics might have it I guess). UPDATE: I need to correct the misinformation I typed above. The Module bolted under the seat is actually the lateral-G sensor (for ESP etc). The module for the seat sensor is on the front edge of the cushion itself. #11 · Apr 18, 2011 That's what I was hoping mine was, the wiring.. but it checked out. I've had no problems with it since replacing the module. My total cost included the diagnostic and reprogramming. I'm thankful my mechanic had the tools to do it all. #12 · Nov 14, 2011 Same happened to me, what's the most probably faulting piece? #13 · Nov 16, 2011 Hard to say without troubleshooting your system, and finding somebody with the knowledge AND the tools to repair it, (of course that doesn't include the part(s) if any).. the easiest is obviously a "loose" connection somewhere in the system.. I have also heard and read that you must be careful because touching something you should not could, and I emphasize could fire off the air bag by shorting across something you should not...:skep: :eek:

so be careful!! 0 Reply #14 · Mar 11, 2012 My 07 RL 93K miles has the same issue - throwing the same code. At the same time, one of the headlights went out (short/disconnected somewhere... again). Not willing to pay 600 to 1000 for a senor though :eek:

#15 · Oct 25, 2012 (Edited) I recently got the 'Service Air Bag' message and was wondering how expensive it would be to replace it (again) :banghead: since this time it is not under warranty? :confused:

I noticed a preformed pocket under the passenger side seat but there's nothing sitting there. Should there be a module of some sort sitting there? I only have wires connected to the sensor up inside the passenger seat. Seems odd to have a preformed empty pocket...is my car missing a module? I did have it serviced before for the same airbag message/warning. Hmmmm...:willy: #16 · Oct 25, 2012 (Edited) The electronic module is glued to the front edge of the bottom cushion. The sensor mat is glued to the top of the cushion. There is no other module under the cushion (though there is the accelerometer module bolted to the floor under the pass. seat)...

#17 · Oct 26, 2012 (Edited) :cheers: Thanx for the info. I am guessing that the accelerator module is for the 2.0 Turbo Sky only? :confused:

My base 2.4L has no such module bolted underneath. :nono: My 2.4L comes nowhere near reaching the 2.0's speed. :nonod: My stupidity at the time opted for the base. :banghead: Thanx again! :thumbs: 0 Reply Insert Quotes Post Reply
