Not sure what your asking but I can tell you how it acts in the three modes

in 2wd I get full bars
in 4 Wheel high I get full bars
in TOD it acts normally

Basicly any time the TOD ECU sees the resiters instead of the TOD solenoid it gives me full bars. However it dose not give me any check TOD lights. I have been driving it daily for several weeks in 2wd and have had no issues.
