Code b223d

Hello, this code indicates that there is a code stored in the Airbag module.
There can be a code for any one of the Occupant Restraint system sensors or module faults. The system will need to be scanned with a scanner that can read into the Airbag module. Most cheaper off the shelf scan tools can only read codes from the Engine Computer, so they would get a code like Pxxx, the P meaning PowerTrain. But the B code is for a different system. So really a full system scan should be done. I'm not sure what kind of scan tools AutoZone or Advanced Auto use, it might not be one that can read into the correct modules. You can try there first, but it might have to be a shop with a scan tool capable of doing full system scans. The Airbag system is one you may not want to try fixing yourself. The airbags can deploy very easily if it is not worked on with the correct procedures. With that system, you have to unhook the battery and wait a certain amount of time before unplugging things and checking sensors. The sensors work at very low current/voltage and most of them need to be replaced with OEM or the original manufactures equipment.
Airbags are extremely expensive if they go off. So, I recommend taking it somewhere to have it worked on.
