Electronic Accelerator Control Actuator
WARNING: This page is about a different car, the 1992 Mercedes-Benz 400E. However, it is still accessible from the selected car via links, so may be relevant.
The electronic accelerator control actuator is only used on vehicles equipped with Acceleration Slip Regulation (ASR). Throttle valve position is set (adjusted) differently from driver input for cruise control operation, idle speed control, and during Acceleration Slip Regulation (ASR). During an ASR event, throttle valve may be set (adjusted) slightly closed from driver input to prevent drive wheel slippage. The electronic accelerator control module uses input from various sensors and other control modules to adjust electronic accelerator control actuator independently from driver input during an ASR event to prevent drive wheel slippage.
