Hello, my name is Bobby. Thank you for the question. Typically when there is a loss of voltage it is common for the air bag light to come on. Most of the time it will show a code for low voltage. The best way to clear this is with a scan tool that reads the air bag system. If you do not have one then disconnect both battery cables and touch them together. Then reinstall the positive followed by the negative. If the problem persists then you may have an issue with the programming now. I hope that the battery cables were not installed incorrectly when the battery was installed. Please let me know if you need more help.
