A regular scanner will not access sirs codes, you need one designed for that. A highline pro unit will.

using a modis snap on scanner $5000..updated 2 weeks ago

That should access Sirs info.

[Tech II]

When you can't communicate, with ANY module, you check for power AND ground to the module, AND you check the data line to it....if those check out ok, then you have a bad module....

If you plan on tinkering with a sir system and dont have proper equipment or training all i have to say is wear ear protection and keep yourself out of the way of where the air bags deploy. That said i agree with tech II. Power and ground first. If both check out then module. On a dif note a scanner of that quality should tell you if there is a circuit fault be it ground or insufficient current.

not all that common where the module is corroded .. that is why I said it was removed because that is how the bag error you got indicates . people are disabling air bags due to Takata grenade reports .

now I think I am going to have to go to dealer and have it programed...???
then the 2012
