07 Caliber Airbag issues
 

Hey guys
so I recently got my heater core serviced, and when the car was returned to me the light on the dash as well as my passenger air bag is off, we believe it may be a power issue, but not sure because we can't read the codes. The fuses he said we're ok, he tried the whole turning the key three times to get the code, but he can't read my car. So basically I'm without airbags until I know what's up. Any ideas?
Thanks
