An error has been detected in the system and first thing you need to do is to get a scan done to check for trouble codes.

There are instances when trouble codes are not found and the problem of the AWD disabled light staying on is caused by loose wiring or a faulty differential clutch pump actuator.

PRoblem of ABS light staying on could be related to the AWD light or it could be a separate issue which could be due to a sensor fault. The scan should throw some codes.
