Cannot get the readiness monitors to show, DTC page loads, clears ect but no readiness data. Saw it update once in ~100 tries but disappeared as fast as it loaded. Used to work on 2.x but since dl 3.x and 4.0.12 VCM suite no joy. Emissions test due soon and would like to see if it's ready before I go.

2012 Camaro LS3, E38, OS 12649046

Any info appreciated, searched to no avail. Thanks!
