I got some codes from the dealership on my car for the airbags and was just curious if anyone could tell me what they are? they wanted to charge me 105 dollars to tell me what the codes were for. B1890 and B1318 any help would be appreciated thanks!

DTC B1890: Passenger air bag deactivation indicator short to battery. Lamp flash code: 18

Possible Source(s):

* Circuit(s).
* Passenger air bag deactivation indicator.

DTC B1318: Battery voltage low. Lamp flash code: continuous

Possible Source(s):

* Battery.
* Charging system.
* Circuit.


The first two things I'd check are your battery voltage with the engine on and off.

And check if your passenger airbag indicator light is working, you may just have a burned out bulb there. It should turn on for a few seconds every time you start your car, then turn off. I had to replace mine, and it has to be the specific low wattage bulb or it will keep throwing a code. That bulb part# is also used as the glovebox light so you could test it by swapping them, cost me about $5 to order one.
