2004 Volvo S80 6 cyl Automatic 117000 miles

MY 2004 S80 is having some weird issues occur. When the car is first turned on the airbag light comes on in the dash, the tachometer needle moves a little but then everything goes blank. The only light left on the dash is the check engine light. The keyless entry doesnt work, the climate control system works except the a/c doesn't cool, it simply blows air, the trunk won't pop, the auto door locks dont work, and I'm pretty sure the car is in 3rd or 4th gear when driving.

I took it to the Volvo dealer today to have it diagnosed. I purchased the car a year ago from a Volvo enthusiast to say the least. He knows everyone at the dealership and he offered to meet me there. Well, apparently my wife had driven through a horrible lightning storm yesterday prior to the malfunction, I guess it some how knocked out the computer (SIM) module located on the underside of the steering column. The mechanic actually had to drain the battery to get the car to repsond to his diagnostic tool. Long story short, the mechanic said that either strong power lines or a lighting storm messed it up (he said this before we had mentioned going through a bad storm) and he somehow kicked the computer back online. I only had to pay 100$ under the table. I am so relieved I was anticipating a huge bill.

Well you did get lucky that they were able to bring the CEM (Central Electronic Module) back online by doing a battery reset, so just keep an eye out for any weird stuff that may happen and keep me posted as to what happens? Sometimes a battery reset will only help for a while and then act up again?
