I to now have an IABS problem in my 05 rt and per the GS-911 it is related to to high a pressure in the rear wheel wheel circuit. I only have residual breaking in the rear brakes. I am posting this to let folks know that I contacted Module Masters today and was told that they are down to 2 parts in the module that they are still working on to be satisfied with before they can start up again with rebuilds. They asked me to callback the first of next year to see where they were then. Lets hope they can get it sorted out for the many of folks that need help.
