ASR Control Mode

As soon as a drive wheel has a tendency to slip, the ESP control module (N47-5) actuates the high-pressure and return pump (A7/3m1), the rear axle switchover solenoid valve, the rear axle precharge solenoid valve and the solenoid valves for the rear axle. The solenoid valves for the left or right of the rear axle are actuated separately.
