Check AWD System and IMA light

Driving around the other day and I got a Check AWD light. Luckily its still under warranty. It goes in tonight for a check. But anyone had any experience or have any insight into a message from the AcuraLink for Service 71 ?

Also, that IMA light on the dash. Has anyone seen that before? It doesn't seem to be in the manual.

Thanks
