This link pertains to the L5D engine in the new 4500/5500 trucks. Apparently, if you shift the transfer case into 4WD low or high WITHOUT locking the hubs, the ECM/TCM will set several codes for injectors.
Has something to do with changes in crankcase rotational changes.

I haven't tried this with mine, and I doubt Hankbambam has either and we are the only two here that have these trucks I think.
