Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi and thank you for your question. Sorry to hear your vehicle is having this issue. These codes are separate codes. It looks like you may have two different issues happening simultaneously. You'll need to have a GM dealer pull the codes in order to find out the rest of the codes. There should be two more digits after the b0081_ _ and b0084_ _. These other numbers / letters are critical to diagnosing the issue correctly. Although, the B0084 is most likely just a faulty RF impact sensor. This is fairly common. However, the missing codes from the B0081 will tell you a lot more about the RF passenger presence system fault.
