Got the pin run today to the IPC, and messed with the programming a little bit.
Changed the IPC 720-01-03 to that of a PP SHO
Then changed the ABS. I got the same warning of the collision detection as others had, so I tried a couple of modifications to the the ABS 760-01-03 address. The stock on my Flex was 0601, the value for the PP seemed to be 4001. The first 4 allows you to actually use the button to change the modes, as I tried changing it from 0601 to 4601 and the modes became available. However, even with the modes enabled, it still was throwing the traction control on. Next I moved to the 6. If you change it to 0, the modes seem to work as designed, however collision detection is disabled. If I set it at 2 however, I don't get the alert that collision detection is disabled and the modes seem to work as designed.
Just my findings on the matter, and anyone following should understand the risks of modifying this data.
