Battery went low over night and had to be boosted. Ran for 2 seconds and shutdown & would not turnover even when connected to boosting vehicle. Disconnected battery and waited 5 mins. Started good after that but now dash has warning lights, no cameras & side steps are not extending or retracting. Any ideas?

As discussed on here many times, if you disconnect the battery, it can take up to 6 hours for everything to come back. The various systems need to talk to the BCM and reconfigure it.
