Hello,

My daily driver is a Silver '08 Grand Prix GXP with the LS4 V8. The car was well taken care of before me with 112K on the clock. The airbag light randomly comes on and goes off. Sometimes it stays off for several days, then it pops on and stays on. Other times it stays on from the start. If I stop and restart it goes off. I'm thinking it is a sensor and not the module since it is random. The problem is, which sensor. I'm told the ODB2 diagnostics will tell me which sensor it is from stored codes. The car has been in an accident, and fixed professionally, prior to my purchase

I would like to purchase a ODB2 diagnostic tool that will read SRS codes because the closest mechanic quoted me $55. I know the dealer will be over $100, but is there an inexpensive tool for GM that someone recommends? I would rather pay twice the charge to own one for my GXP.
