Electronic Throttle Control Module: Description and Operation
Electronic Accelerator System Schematic
PURPOSE
The electronic accelerator control unit (N4/1) controls the cruise control, idle speed functions and electronic engine control (electronic accelerator
pedal) for ABS/ASR III to insure smooth and consistent operation regardless of engine temperature and load.
LOCATION AND I.D.
The electronic accelerator control unit is located in the module box (F23) and is color coded light orange.
OPERATION
When the ignition switch is in the ON position, the idle speed control function is in operation. The position of the throttle valve for idle speed and
ABS/ASR III is determined by the control unit via the nominal value (accelerator pedal input) potentiometer in the electronic accelerator actuator
