ADS II Throttle Control/ASC+T DME/EGS Interfaces

ADS II Throttle Control

The ADS II motor is controlled by a modulated signal (PWM) from the ASC+T control module.

As the accelerator pedal (1) is depressed, power is applied to the rear wheels. If slip is detected by the ASC+T control module, ASC regulation commences.

The degree of closure is dependent on the degree of slip and the control module programming. The ADS motor (2) closes the throttle (3) through the bowden cable.

The ASC+T control module receives feedback acknowledgment (4) of ADS operation from the potentiometer mounted on the throttle housing.

In addition to the ADS position of the throttle, the ASC+T control module also receives the DKI signal (5) from the DME as a plausibility input.





ASC+T - DME/EGS Interfaces

The signals between the ASC+T control module and the DME control module for slip control regulation are switched high/low signals. In addition to the DKI signal the ASC+T interfaces with the DME over three signal paths.

^ S-EML - Signal to DME of ADS throttle regulation.

^ S-MSR (ZWV) - During slip control regulation this is a signal to the DME to retard the ignition timing.

^ S-ASC (ZA) - During slip control regulation, this is a signal to the DME to briefly fade out the ignition/injection.

^ SHIFT INTERVENTION - This is a signal from the ASC+T control module to the EGS control module to suppress shifting during ASC regulation.
