Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

SRS Light Due to Spilled Liquid on Buckles or Underneath Seat

The SRS (airbag) light can come on if liquids are spilled into the seat belt buckles, or if the liquid pools underneath the seat and gets into the electrical connector for the seat belt pretensioner. Damaged components will require replacement to restore proper airbag operation.
