controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel.

Applying the brakes very quickly results in the best BAS assistance. To receive the benefit of the - 2008 Jeep Grand Cherokee | Owner's Manual - Page 141
speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicles speed are sufficient to potentially cause wheel lift, it then applies the brake of the appropriate wheel and may also reduce engine power to lessen the chance that wheel lift will occur. ERM - 2008 Jeep Grand Cherokee | Owner's Manual - Page 142
) This system enhances directional control and stability of the vehicle under various driving conditions. ESP corrects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition. Engine power may - 2008 Jeep Grand Cherokee | Owner's Manual - Page 143
