5 V Reference	Regulated voltage supplied by the control module.
Serial Data	Digitally encoded information for communication between devices.
Low Reference	Grounded through the control module.

Component	Description
K20 Engine Control Module	The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly.
M103 Turbocharger Vane Position Actuator	The assembly has several functions: The component is actuated by a bidirectional DC motor. The component M103 contains a contactless inductive position sensor. A fixed transmitter coil excites a movable rotor, which in turn induces a current in a fixed receiver coil. The current varies with the angle of the rotor. Electronics inside the sensor convert the current into digital data which is transmitted via a serial data circuit to the control module K20.

K20 Engine Control Module

The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly.

M103 Turbocharger Vane Position Actuator

The assembly has several functions:

The component is actuated by a bidirectional DC motor.
The component M103 contains a contactless inductive position sensor. A fixed transmitter coil excites a movable rotor, which in turn induces a current in a fixed receiver coil. The current varies with the angle of the rotor. Electronics inside the sensor convert the current into digital data which is transmitted via a serial data circuit to the control module K20.

The engine control module performs the learn function for the turbocharger vane position automatically in certain intervals.
