My wife's 2007 Saturn Vue which has 42K miles on it. We purchased it new and it's a great car until this week. The airbag light flashes but when I connected the tech2 to read codes, it says, no communication to the SIR module. The fuse is good. Before I take it to the dealer to have it looked at, any suggestions? Thanks,

 

Disconnect the battery ground cable for a couple of minutes and then hook it back up. It may be a fluke and you just need to reset the computer. If it comes back, then you probably need to have it checked out.

 

Look up "Drive Cycle" and do it.

 

Sorry......drive cycle is for resetting the computor so it will talk to the TECH II ... Someone with a tech II should know this.
