What he is saying is that the computer will disable regen braking under either cold conditions or wheel lockup. I'm not sure I would want to mess with this if it could mean losing ABS. Is the "OAT" sensor used to determine whether this occurs something different than the IAT sensor? You wouldn't want to mess with the intake air temps, at a minimum this would probably hurt fuel economy, if not the engine itself. If it is using a dedicated sensor that still leaves the ABS issue.
