My 2013 RHD jeep wrangler is showing codes B1B02 and B1B06. I took it to jason lewis automotive in sparta tn yesterday. The airbag light is on and the horn does not work. These are the exact same failures identified in safety recall s40. The previous owner of my car got this done in 2021 but the remedy has failed and the safety risk is back. They confirmed that the clockspring is bad and needs replacing. The confirmed the codes and it matches the s40 recall.
