Help me understand how the Steering angle sensor and Psm Module affect ABS?

[thstone]

Both ABS and PSM use the wheel sensors to provide wheel speed inputs.

The steering angle sensor is used by the PSM (along with all of the other inputs) to calculate the slip angle of the tires.

Then the PSM will determine if the car is understeering or oversteering and apply braking to an individual wheel as needed to help maintain control.

Porsche allows PSM to be turned off while ABS remains active but I don't know if you can force the PSM off permanently.
