DescriptionThe Cruise Control function - constant speed regulator - allows the car to be driven at a constant speed without pressing the accelerator pedal.The function is managed by the engine control unit which receives the commands from the special Cruise Control lever on the left of the steering wheel, under the steering column switch unit.The function is switched on by turning the ring nut (ON).When a speed is set (SET +, SET -) it remains memorized and can be recalled at any time (RCL).The function is automatically switched off:by pressing the brake pedal;by pressing the clutch pedal;by turning the ring nut to OFF;by turning off the engine;In these cases the last speed reached is memorized, and can be recalled by pressing the RCL button.The system also switches off at vehicle speeds below the permitted minimum (about 30 km/h)When the function is switched on, the relevant warning light on the instrument panel, connected via the CAN network to the engine management control unit, comes on.

Functional description The Cruise Control function is controlled by engine management unit M10 upon a command from the Cruise Control switch H7 located to the left of the steering wheel. The switch H7 is supplied when the ignition is switched on (INT) - pin 2 - from the line protected by the fuse F35 of the unit under the dashboard B2. Control H7 is connected to management unit M10:at pin 20 of connector A, with the ON/OFF signalat pin 22 of connector A, with the RESUME signalat pin 21 of connector A, with the SET + signalat pin 19 of connector A, with the SET- signal To manage the Cruise Control function, control unit M10 also uses 'pedal released' signals (N.C. contact) coming from the second contact for the brake lights switch I30 and the clutch presssed signal from switch I312399345SeeE5050DIESEL ENGINES ELECTRONIC MANAGEMENT . Via the CAN line, the engine control unit M10 is connected to the Body Computer M1 and the instrument panel E50 , to manage the 'Cruise Control on' warning light.
