Low speed

When starting on a slippery surface, the following will happen:

The drive wheel having the lowest friction begins to spin first. When wheelspin is detected by the control module through the wheel sensors, TCS modulation starts by applying the brakes.

When the wheel is braked, additional tractive power is transferred to the other wheel which still has a grip on the road. If the road surface does not have much friction, the other wheel may begin to spin. When wheelspin occurs, the control module will send an engine torque limitation request to the ECM which then prevents further wheelspin.

The optimum combination of tractive power and steering ability is thus achieved as well as the same traction as with the use of a differential brake.

A relatively high degree of wheelspin is accepted when starting in order to retain the feeling of sportiness and also enable the wheels to dig themselves down to a firmer surface whenever conditions make this necessary.
