What is Abuse Mode, & Differential Scoring Protection?
Abuse mode is when the PCM detects wheels spinning, like in a burnout.
Differential scoring protection is when the PCM detects one front drive wheel spinning and the other not, like in a one wheel burnout. The pinion in our differentials is suseptable to scoring and breakage during that condition.
So when these modes are detected, the PCM pulls timing and shuts down injector fuel flow to lower the power in order to stop the abuse and protect the drivetrain.
