Visual Red Triangle code illuminated on the instrument cluster with the number 1 on the side of it. I used my OBD2 reader (Blue Driver) to retrieve the 8 AIR BAG codes. They were B1511 ,B1513, B1378, B1382, B1346, B1481, B14AE, B2618. Problem resulted after the Cowl Cross Bar Assembly (Unpainted), also known as a CRASH BAR, was replaced because of broken welds. It was replaced with a Painted Assembly that prevents access to secure ground for the Air Bags and Seat Belts.
