Cause of GM airbag light on

GM has determined that these airbag trouble codes can be caused by interference from an aftermarket USB and/or phone charger plugged into the 12 volt power outlet. The solid-state electronics in the charger can cause excessive airbag loop resistance or varying resistance.

Start your diagnostics by unplugging all aftermarket plugin or add on electrical accessories. The clear the codes and see if they return. If they do, replace the devices one at a time until you identify the problem device.
