Cruise Control Signal Active, to Engine Management System

For the engine to go down to basic charging pressure, the Trionic needs to know when cruise control is active. This information is sent to the Trionic via pin 9 (J).
For smoother control of the car's speed when cruise control is active, boost pressure is limited to basic charging pressure. The Trionic transmits about 10 V via a resistor. Pin 9 (J) is grounded when cruise control is active, causing the voltage on Trionic pin 36 to drop from 10 to 0 V.
Boost pressure will now be limited, which means that the engine will develop slightly less power, making it easier for the cruise control system to control the car's speed.
